Desired functionality.

AOT build should be successful

Mention any other details that might be useful.

The project built fine with AOT enabled with CLI v1.4.9

[DavidDNA]

Same issue here with @angular/cli 1.5.0

Works without aot.

[Axure]

Same here, except that it does not work either without AOT. Without AOT, it takes over 140 seconds to build, and throws the following error when actually running:

[samalexander]

@Axure it builds successfully for me with ng build --prod --aot=false

[Axure]

I seem to have found out the problem. The problematic code there is:

        switch (node.kind) {
            case 229 /* ClassDeclaration */:
                // classes are valid targets
                return true;
            case 149 /* PropertyDeclaration */:
                // property declarations are valid if their parent is a class declaration.
                return node.parent.kind === 229 /* ClassDeclaration */;

It seems to fail to find the parent of the node when the node is a property declaration. I suddenly realized that it was the @select decorator from angular-redux, and I'm pretty sure the decorator is valid. So I tried adding the following line to bypass the check.
if (!node.parent) return true;
And it turns out to be working.

Facing this issue with Angular Cli 1.5.2
Works fine with 1.5.0

Angular Version: 1.5.2

[cerebroo]

@arsyed04 - Yup was getting error with Angular Cli 1.5.2 but worked fine when rolled back to 1.5.0
Thanks.

Not sure if it's really needed but my TypeScript version was 2.6.1

[arsyed04]

My typescript version is also same "typescript": "^2.6.1"

[elvisbegovic]

same error and my version is "typescript": "~2.4.2"

[billcheng]

Same error with cli 1.5.2. Downgraded to 1.5.0 and it worked.

Edit: I've also narrowed it down to a specific decorator I'm using throughout my app. Removing the instances of the @Throttle() decorator (from lodash-decorators) from my app "fixes" my issue.

[bvoisin]

In my case, the error was caused by arrow functions used as parameters of decorators.
IE : @someAnnotation(t=>!!t) someField; for example
To find them, use a Regexp search or add a console.log in the typescript.js file before re-compiling :

 case 149 /* PropertyDeclaration */:
              if (!node.parent) {    
                console.log("###### No Node parent on " + node.name.escapedText);
            }
                // property declarations are valid if their parent is a class declaration.
                return node.parent.kind === 229 /* ClassDeclaration */;

Then it was easy to replace those with named function

function someFn(t) {
   return !!t;
}
[...]
@someAnnotation(someFn) someField; 

[akartynnik]

Huge THANK YOU! You are save my time :)

[ericmarcos]

I'm having the same problem and found it's because of arrow functions in decorators, like:

@Type(() => Message)

When I change the above to:

function m() { return Message; }
@Type(m)

It compiles with AOT again =)

[niveo]

https://github.com/typestack/class-transformer/issues/108

@rmrevin

export function serializeType<T>(object: T) {
  return function () { return object; }
}

export class CatalogItem {

  id: string;

  @Type(serializeType(CatalogCategory))
  category?: CatalogCategory = null;

  @Type(serializeType(PackingVariant))
  packing: PackingVariant;

  price: string = null;

}

[seangwright]

Angular CLI: 1.5.4
Node: 8.9.1
OS: win32 x64
Angular: 5.0.3

I'm having an issue with a @Debounce decorator.

Using the above console.log() in typescript.ts I get ###### No Node parent on onWindowChange for case 151

export function Debounce(delay: number = 300): MethodDecorator {
  return function (
    _target: any,
    _propertyKey: string,
    descriptor: PropertyDescriptor
  ) {
    let timeout: any = null;

    const original = descriptor.value;

    descriptor.value = function (...args: any[]) {
      clearTimeout(timeout);
      timeout = setTimeout(() => original.apply(this, args), delay);
    };

    return descriptor;
  };
}
  ...
  // inside component class ...
  @HostListener('window:orientationChange', [])
  @HostListener('window:resize', [])
  @Debounce()
  onWindowChange() { ... }

Replacing the decorator with the timeout code in onWindowChange() fixes the issue.

[MohammedYaseen]

@Axure

I use @select decorator from angular-redux, locally i can run the app without any problems, however when i try to build it in prod i get the same error above. I don't want to edit the typescript.js file manually to bypass the check. any suggestions ???

[Axure]

@MohammedYaseen I'm not sure, but probably using a custom github repo as registry for the dependency typescript in package.json would work. See this for example.

[MohammedYaseen]

@Axure, Ok, thanks

[hccampos]

We are having the same problem and have been stuck on 1.5.0 because of it. In our case it happens even without arrow functions being passed to decorators

The cause in our case is some decorators being applied to properties that also have Angular decorators (usually @Input) applied to them. Everything works in JIT mode but AOT fails. Stepping through in the debugger we can see that the node's parent is gone and there is no null check to prevent it exploding (as mentioned above by another commenter).

We will probably end up removing the custom decorators anyway (can't rely on decorators at all), but until then, we are stuck or will have to hack Typescript.

Any news on whether this is being looked at? Would a PR to Typescript or the CLI be acceptable?

[hccampos]

@filipesilva @SanderElias here is a repro for this bug https://github.com/hccampos/angular-cli-repro-8434

[el-davo]

In my case it turned out to be the fact that we were using 2 decorators on a function Our code was like this, which should work and is valid

@HostListener('document:keydown.escape', ['$event'])
@dispatch()
onKeydownHandler() {
      return this.actions.hideOverlay();
}

Changing to below got rid of the error

@HostListener('document:keydown.escape', ['$event'])
onKeydownHandler() {
    this.hideOverlay();
}

@dispatch()
hideOverlay() {
   return this.actions.hideOverlay();
}

[elvisbegovic]

@el-davo can't if i've class decorator an property decorator as @hccampos said

[kostia24]

Error fixed in typescript version 2.7.0-dev.20171201
https://github.com/Microsoft/TypeScript/pull/20314

[elvisbegovic]

@filipesilva can you please get a look here? actually blocking build process (aot)

[paulchill]

Have a similar issue
AOT build wont work, have to use --prod with --aot=fallse

at nodeCanBeDecorated (node_modulestypescriptlibtypescript.js:7811:36)

[arsyed04]

Downgrading angular-cli seems to be the only solution at the moment.

[gmavritsakis]

I had the same issue with:
Angular CLI 1.6.1
Typescript 2.4.2
Angular 5.0.2

Found a solution by changing typescript.js for now.
Replace all the function
function nodeCanBeDecorated(node)
with the following code
```
function nodeCanBeDecorated(node) {
switch (node.kind) {
case 229 /* ClassDeclaration /:
// classes are valid targets
return true;
case 149 / PropertyDeclaration /:
// property declarations are valid if their parent is a class declaration.
// return node.parent.kind === 229 / ClassDeclaration /;
return (node.parent && node.parent.kind === 229) || (node.original && node.original.parent && node.original.parent.kind === 229);
case 153 / GetAccessor /:
case 154 / SetAccessor /:
case 151 / MethodDeclaration /:
// if this method has a body and its parent is a class declaration, this is a valid target.
return node.body !== undefined &&
// && node.parent.kind === 229 / ClassDeclaration /;
(node.parent && node.parent.kind === 229) || (node.original && node.original.parent && node.original.parent.kind === 229);
case 146 / Parameter /:
// if the parameter's parent has a body and its grandparent is a class declaration, this is a valid target;
// return node.parent.body !== undefined
// && (node.parent.kind === 152 / Constructor /
// || node.parent.kind === 151 / MethodDeclaration /
// || node.parent.kind === 154 / SetAccessor /)
// && node.parent.parent.kind === 229 / ClassDeclaration */;

            var parent = node.parent || (node.original && node.original.parent);
            return parent && parent.body !== undefined &&
                  (parent.kind === 152
                     || parent.kind === 151
                     || parent.kind === 154) && parent.parent.kind === 229;
    }
    return false;
}

```
Which comes from here, if you compile typescript:
https://github.com/shlomiassaf/TypeScript/commit/7017fa2a0a8137279230f04b59a6ec89f6928331

[cjking-wang]

"@angular/cli": "^1.6.1"
Also throw this error

[arsyed04]

@gmavritsakis Is it angular-cli issue based on your deduction or typescript?
I have upgraded all my other libraries including angular and typescript, but issue arise only when I upgrade angular-cli.

If it is angular-cli issue, I strongly recommend you create a pull request with your fix above so that it can be merged into release.

[kevinphelps]

When I try using [email protected] (which contains the fix), I get this error from the Angular CLI:

Could not find local "typescript" package. The "@ngtools/webpack" package requires a local "typescript@^2.0.2" package to be installed.

The dev version string apparently fails this check: https://github.com/angular/angular-cli/blob/master/packages/@ngtools/webpack/src/index.ts#L9

[glebcha]

Can verify that it's angular-cli issue. Rollback to v1.6.0-beta.0 proved that.

[r-winkler]

I downgraded to angular-cli 1.5.0 and error is gone.

[artstar]

Is there any version of ngtools/webpack without this error?

[danielsogl]

Install the latest CLI release 1.6.3 and install typescript@next.

[petivagyok16]

@danielsogl Your tip solved the issue for me. Thank you!

[emilio-martinez]

Is there a fix path where an upgrade to typescript@next isn't required? I would think this is a angular-cli regression issue since downgrading avoids the error

[emilio-martinez]

Also @angular/compiler-cli as of v5.1.2 seems to require typescript@>=2.4.2 <2.5.0. Cross-linked issue above where, quote:

If you 2.5 or 2.6 with ngc version 5.0.3 it will silently produce bad output in certain cases

Given that's the case, I don't think it's necessarily secure to upgrade to TS 2.7-ish. See also from https://github.com/angular/angular/issues/21157#issuecomment-353767980:

We have no idea if 2.7-dev is compatible or not.
Typically every minor version of typescript changes the AST apis which break our compiler so we need to tweak things every time.

[emilio-martinez]

@filipesilva sorry to pressure, but is there any progress to report? For our teams, the CLI is currently frozen on v1.5.0.

[lexon0011]

I had the same issue. I could resolve it with installing dev version of angular/cli and typescript:

npm install @angular/cli@next
npm install typescript@next

[clydin]

The underlying cause is a defect in TypeScript which is fixed in newer versions of TypeScript. The CLI in more recent versions uses more capability of the TypeScript transformation subsystem. This in turn exposed the TypeScript defect to CLI users. As newer versions of TypeScript are not yet officially supported by Angular, the CLI will need to add a workaround for the underlying Typescript defect. The CLI already has a workaround in place for a different decorator related defect and this should be able to be augmented to support handling the defect here as well.

[lexon0011]

After installing the angular/cli dev version, I get the following problems: Stackoverflow - Angular CLI - After refreshing in browser the browser try to load files from a wrong location

[philjones88]

@Brocco @clydin I still get the issue in the 1.6.5 cli version, I undid a class-transformer workaround (show at the end of this comment) and I still get the same kind error:

Typescript: 2.6.2

Workaround used:

export function serializeType<T>(object: T) {
  return function () { return object; };
}

...
@Type(serializeType(Participant))
public participants: Participant[] = [];

[samalexander]

I am also seeing the same issue with angular-cli v1.6.5

[arsyed04]

@philjones88 where did you apply this workaround? Is it general fix?

[philjones88]

@arsyed04 I applied it to any usages of @Type(() => MyType) from the class-transformer library I had in my application

[felipefialho]

Same issue with "@angular/cli": "^1.6.8"

[sparvov]

issue with md-bootstrap is fixed with typescript 2.7.1

'Component' calls 'ɵmakeDecorator'

I changed it to: 2.7.0-rc
that fixed it.

Then i run ng build --prod:
Now it cries:
ERROR in Cannot read property 'kind' of undefined
searched all day to fix that error: but never found a solution has anybody ever found a solution this this error?

2) anyone knows what version of node is recommended for Angular 5.2.10?
my nvm lists has:
8.9.4, 8.9.0, 7.6.0 & 7.10.1

So this fix worked for me:
I was using nvm (node version manager) and switching between node versions to find the solutions,
you have to select the right version of node, I have 64bit version and node-sass was asking for 32bit version.

I had to do: npm rebuild node-sass
but then after a build I had that error, during node-sass rebuild I noticed it was saying it could not find python 2.

So I ran the command from powershell as administrator:
npm --add-python-to-path='true' --debug install --global windows-build-tools
npm install --global node-gyp

then I switch to a 32 bit node version:
nvm use 7.x.x 32

you can check your nvm version with the command:
nvm list
7.6.0 (Currently using 32-bit executable)

So that fixed that, then I ran:
npm rebuild node-sass

then tried to find a compatible typescript version that would not torment my production build:
"typescript": "^2.6.2"

that fixed my issues.

so the only error I am seeing now is:
Function calls are not supported in decorators but 'ɵmakeDecorator' was called in 'Component'
'Component' calls 'ɵmakeDecorator'

but this is manageable.

I had same problem today.

TypeError: Cannot read property 'kind' of undefined (...)

...and I fix it just upgrading my Typescript for 2.6.2.

These steps worked for me:
1)Clear package.json with the importat packages for example I have delete my package and insert one by one here is my

{
  "name": "test-app",
  "version": "0.0.0",
  "scripts": {
    "ng": "ng",
    "start": "ng serve",
    "build": "ng build",
    "test": "ng test",
    "lint": "ng lint",
    "e2e": "ng e2e"
  },
  "private": true,
  "dependencies": {
    "@angular/animations": "^6.1.0",
    "@angular/cdk": "^6.4.2",
    "@angular/common": "^6.1.0",
    "@angular/compiler": "^6.1.0",
    "@angular/core": "^6.1.0",
    "@angular/flex-layout": "^6.0.0-beta.17",

    "jquery": "^3.3.1",
    "rxjs": "^6.0.0",
    "rxjs-compat": "^6.2.2",
    "webpack": "^4.16.3",
    "zone.js": "~0.8.26"
  },
  "devDependencies": {
    "@angular-devkit/build-angular": "~0.7.0",
    "@angular/cli": "^6.1.2",
    "@angular/compiler-cli": "^6.1.0",
    "@angular/language-service": "^6.1.0",
    "@types/jasmine": "~2.8.6",
    "@types/jasminewd2": "~2.0.3",
    "@types/node": "~8.9.4",
    "codelyzer": "~4.2.1",
    "jasmine-core": "~2.99.1",
    "jasmine-spec-reporter": "~4.2.1",
    "karma": "~1.7.1",
    "karma-chrome-launcher": "~2.2.0",
    "karma-coverage-istanbul-reporter": "~2.0.0",
    "karma-jasmine": "~1.1.1",
    "karma-jasmine-html-reporter": "^0.2.2",
    "npm-install-webpack-plugin": "^4.0.5",
    "protractor": "~5.3.0",
    "ts-node": "~5.0.1",
    "tslint": "~5.9.1",
    "typescript": "^2.7.2",
    "webpack-cli": "^3.1.0",
    "webpack-dev-server": "^3.1.5"
  }
}

2) delete package_locked.json
3) delete node_modules folder
4) npm install
5) Then ng build --prod was successful.

The problem might be in the ^ of the packages. IN my case the problem was typescript version I had
"typescript": "^3.1.3", and npm installed version 3.2.2.

Changed to "typescript": "3.1.3", ran npm install and the problem got fixed.

[EssieShey]

I believe you missed type of chartist package.
Try below:
npm install chartist
