   @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.

   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: webpack@1.x.x || 2.x.x, required by string-replace-loader@1.0.3

   In the meanwhile I installed web pack:
   npm ls webpack -g
   /usr/local/lib
   └── webpack@1.13.2

   But I still get this error:
   npm ls angular-cli
   angular-cli@1.0.0-beta.14 /usr/local/lib/node_modules/angular-cli
   └── UNMET PEER DEPENDENCY webpack@2.1.0-beta.22

   Installed web pack@2.1.0-beta.22 but now I get the "old" message:
   npm ls angular-cli
   ....
   npm ERR! peer dep missing: webpack@1.x.x || 2.x.x, required by string-replace-loader@1.0.3

    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.

    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.

    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.

    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/router: 3.4.3

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