Unable to find "@angular/cli" in devDependencies.

Please take the following steps to avoid issues:
"npm install --save-dev @angular/cli@latest"

Desired functionality.

ng command runs without issues.

Mention any other details that might be useful.

I am not sure this is related, but all new Angular apps I create using the CLI appear in the Home directory instead of the directory the command was run in.

[Ionaru]

It appears this was caused by having a node_modules folder and package.json file in the home directory, probably caused by doing an incorrect npm install command in the past.

I'm going to keep this open actually, we shouldn't check that root package.json really.

I have this same issue, how can I fix this?

[fbownz]

I got the same issue, this was after updating my angular cli on my project folder.

[AndrzejWroGM]

I got it, in my case I had to delete package.json which I create earlier in application folder.

I have the same issue. Please tell me whats is happening. I already run the commands suggested without success and I don't think than need to delete package.json.

[otonielguajardo]

This happens to me only if a package.json already exists in same directory where running "ng new app-name", in my case the package.json I use for my server side node app.

Hi,
I ran into the same problem when I tried to create a component in Angular2 quickstart project. This is what solved my problem.
First make sure you install angular cli as;
npm install -g @angular/cli
then cd to where you want to put your project.

ng new your_project_name
cd your_project_name
ng serve

To add a component, cd to your_project_name and run;
comp@debian:~/Desktop/your_project_name$ng generate component mycompo

This will create your componet under mycompo folder in src/app/mycompo

I changed the following line in _package.json_ from
"angular-cli": "1.0.0-beta.21",
to
"@angular/cli": "1.0.4",
and it worked. For my case that was the solution.

[gaikwad411]

I had the same issue following steps helped me to resolve it,

1. Update package json
   from
   "angular-cli": "anything"
   to
   "@angular/cli": "1.0.4"

2. Deleted node_modules and installed node modules again with
   npm install

3. Change angular-cli.json for
   from
   "environments": {
   "source": "environments/environment.ts"
   "dev": "environments/environment.ts",
   "prod": "environments/environment.prod.ts"
   }
   to
   "environmentSource": "environments/environment.ts",
   "environments": {
   "dev": "environments/environment.ts",
   "prod": "environments/environment.prod.ts"
   }

Closing as this doesn't seem to be an issue anymore.

As otonielguajardo mentioned, this happens when package.json exists in the directory where 'ng new-app-name' is run, as when creating a front-end for a server-side node app. To resolve this, I ran the command in a separate directory, then moved the created folder under my original app folder.

I have a monorepo with following structure:

root
|-packages
| |-angular-package1\
| |-angular-package2\
| ...
|-lerna.json
|-package.json

I am facing the following problem while ng new myapp --routing --directory packages/myapp. If I don't include "@angular/cli": "^1.7.3" in devDependencies it complaints about Unable to find "@angular/cli" in devDependencies., and when I do, it tells me You cannot use the new command inside an Angular CLI project.. 🙁
