Angular-cli: ng fails on Version.assertPostWebpackVersion() on 1.0.0-beta.14

[andrevmatos]

1. OS?
   Arch Linux with latest kernel and Node 6.5.0 through NVM
2. Versions:
   angular-cli: 1.0.0-beta.14
   node: 6.5.0
   os: linux x64
3. Repro steps.
   Local installation, empty folder:
   npm i angular-cli
   ./node_modules/.bin/ng init # fails
4. The log given by the failure.
   fs.js:640
   return binding.open(pathModule._makeLong(path), stringToFlags(flags), mode);
   ^

1. Mention any other details that might be useful.
   Commenting out the line 25 on angular-cli/bin/ng makes everything work again.
   This with the check Version.assertPostWebpackVersion(), was added on commit 21003b1dc359e5d32e493911ceb5b72966d4c0ad .

[andrevmatos]

@Aorewen Simplest workaround to continue working in your project is comment line 25 of node_modules/angular-cli/bin/ng :
// Version.assertPostWebpackVersion();
Until it is fixed properly.

[hopefullToo]

I just commented out line 25 on angular-cli/bin/ng .
but now ng hangs if I call ng --help
a new line is displayed and I can enter any text but n nothing happens.
I quit the call with ^C.

I do not know if this has to do anything with this nam error message I got after installing angular-cli:

peer dep missing: [email protected] || 2.x.x, required by [email protected]

In the meanwhile I installed web pack:
npm ls webpack -g
/usr/local/lib
└── [email protected]

But I still get this error:
npm ls angular-cli
[email protected] /usr/local/lib/node_modules/angular-cli
└── UNMET PEER DEPENDENCY [email protected]

Installed web [email protected] but now I get the "old" message:
npm ls angular-cli
....
npm ERR! peer dep missing: [email protected] || 2.x.x, required by [email protected]

[alexverdaguer]

Updated node to v6.6.0 and now it works !

[ValeryVS]

I fix this for node 6.5.0 with #2178

Persisted in v6.6.0 for me

[programmerinprogress]

Same issue for me on node 6.6.0, windows 10, I just get the upgrade warning and I'm asking for the latest version of angular-cli, I've done about 5 re-install cycles now.

[caseyhoward]

I'm on a linux machine and this happens in one directory but not in another. Weird.

Edit: The directory that worked was an existing project. The one that didn't work was an empty project (ng init hadn't been ran). I didn't some investigation and it's looking for the angular-cli.json file. That file doesn't exist until you run "ng init". This seems like a bug. It's impossible to create new projects.

I'm not sure how this would ever work for new projects. The ng bin script checks looks for an angular-cli.json first thing and blows up when it doesn't find it.

[caseyhoward]

Upon further review, I think I see the error:

https://github.com/angular/angular-cli/blob/master/packages/angular-cli/upgrade/version.ts#L79

That line should either check if the file exists or be moved into the try block below (line 82). It's trying to read in angular-cli.json. I'm not sure that's the best fix, but I changed it locally and it works.

[JelF]

@caseyhoward can you make a diff?

nevermind, solved by touch angular-cli.json

[ValeryVS]

@caseyhoward
No need for more try..catch
There is fix, wait for merging

https://github.com/angular/angular-cli/pull/2178/files

Workaround: create blank angular-cli.json

[filipesilva]

@hansl can you have a look?

error on node 6.6.0, npm 3.10.3, osx 10.10.5

[nlovett]

+1

[imho] this should work:

$ mkdir noglobal
$ cd noglobal
$ npm init -f
$ npm i -D angular-cli@latest
$ ./node_modules/.bin/ng init

[tobiasfi]

+1 👍

Same error here.

Windows 10
Node 6.6.0
npm 3.10.2

[GabrielDumbrava]

Same with
Linux
node 6.7.0
npm 3.10.3
angular-cli 1.0.0-beta.16

[tobiasfi]

Strange strange strange:
I get the error in some directories and not in others!!!
e.G. d:/tmp fails but d:/test/tmp works.
I can not find out what distinquishes them, it does not appear to be the name or emptyness ... òO

UPDATE:
After deleting what was inside d:/tmp , it works there too.
Maybe it was emptyness or certain files in that folder or .git ?

[PhilippSoehnlein]

To me it looks like it's a thing about installing the CLI globally or not. It works for me, when I install it via npm install --global angular-cli, but doing it locally (npm install angular-cli) and calling it from my local node_modules-folder doesn't.

[tobiasfi]

I did install it globally and it did not work for me.

[matt-erhart]

Same here. ng -v only worked with an angular-cli.json in the pwd.
angular-cli: 1.0.0-beta.16
node: 6.7.0 (and 6.6.0)
os: win32 x64

No other ng commands seem to be working. Everything was working fine before my vacation about a week ago. Not sure what changed, and why reinstalling everything didn't fix it.

[vadost]

Same on ubuntu 14.04, node v6.7.0, npm 3.10.3. Please help!

[NilsHolger]

angular-cli: 1.0.0 beta.16
ng build --prod
deploy to firebase dist folder
it was a mess, CSS and JS missing
now cli is broken
always get message

I can confirm that this is happening on Mac when trying to bump from .15 to .16

Not sure if this is the same issue, but I'm getting this error:

Path must be a string. Received { source: 'environments/environment.ts',
  dev: 'environments/environment.ts',
  prod: 'environments/environment.prod.ts' }

Newly installed ng-cli with these version:

angular-cli: 1.0.0-beta.25.5
node: 6.7.0
os: darwin x64
@angular/common: 2.4.3
@angular/compiler: 2.4.3
@angular/core: 2.4.3
@angular/forms: 2.4.3
@angular/http: 2.4.3
@angular/material: 2.0.0-beta.1
@angular/platform-browser: 2.4.3
@angular/platform-browser-dynamic: 2.4.3
@angular/router: 3.4.3
@angular/compiler-cli: 2.4.3

Barely did any coding. Added 4 components and one service, also angular/material and now this error is thrown when I run ng serve
