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 21003b1 .

andrevmatos · 2016-09-16T14:14:57Z

@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 · 2016-09-16T14:15:07Z

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

alexverdaguer · 2016-09-16T17:51:41Z

Updated node to v6.6.0 and now it works !

ValeryVS · 2016-09-16T18:02:09Z

I fix this for node 6.5.0 with #2178

mikedsharp · 2016-09-20T19:49:15Z

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 · 2016-09-21T03:04:33Z

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 · 2016-09-21T03:27:47Z

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 · 2016-09-21T07:40:16Z

@caseyhoward can you make a diff?

nevermind, solved by touch angular-cli.json

ValeryVS · 2016-09-21T19:59:04Z

@caseyhoward
No need for more try..catch
There is fix, wait for merging
#2178
https://github.com/angular/angular-cli/pull/2178/files

Workaround: create blank angular-cli.json

filipesilva · 2016-09-22T02:20:14Z

[imho] this should work:

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

tobiasfi · 2016-09-29T10:02:47Z

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 · 2016-09-29T10:33:53Z

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 · 2016-09-29T10:36:18Z

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

jigfox · 2016-09-29T16:52:57Z

matt-erhart · 2016-09-29T21:32:29Z

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 · 2016-10-02T15:40:21Z
