Visit http://ember-cli.com/user-guide/#watchman for more info. angular-cli: 1.0.0-beta.11-webpack.8 node: 6.5.0 os: darwin x64
3. Repro steps. Was this an app that wasn't created using the CLI? What change did you do on your code? etc. Just ran npm install -g angular-cli@webpack
4. The log given by the failure. Normally this include a stack trace and some more information. see below
5. Mention any other details that might be useful. I also tried clearing the npm cache but the results were the same.

Dupe of https://github.com/angular/angular-cli/issues/1560#issuecomment-240913794. Other problems seem related to the upgrade of webpack betas, which is now has better instructions in https://github.com/angular/angular-cli#webpack-update.

@JohnMcGuinness solution fixed the issue for me.

[rfarina]

I struggled with this quite a bit as well. What seemed to work for me was to delete node_modules, and run ng init. I actually followed the following:

It worked for me with a similar solution to @M4ttsson.

Changed the typescript value in my package.json to "2.0.0" Completely removed node_modules folder ran ng init, skipped everything ng serve

[rfarina]

I take it back... back to ground zero...

[lcrespom]

Has anyone managed to install angular-cli as a local dependency? That is without the "-g". Maybe there should be a separate issue for that?

[rfarina]

Thought I'd put this out there... I was getting the same warnings as everyone described. In my code, I am getting 2 messages:

1. Promise name not found
2. Experimental Support for Decorators message

I felt this meant that Promises would not work. I also don't understand why I get the "Experimental Decorator" message.

However, Promises DO work, even though it claims that the name is not found.

Any ideas? Thanks

[lcrespom]

@rfarina, I think that is just a bug in Visual Studio Code, totally unrelated. I keep getting the same problems without angular-cli, I just restart Visual Studio and the problem disappears :-)

[M4ttsson]

I had this problem too. Vs code used an older version of typescript than my project. So it showed these errors but when compiled with the project version everything was fine. I changed vs code typescript version and the problem went away, add the setting typescript.tsdk and point it to the path of node_modules typescript location.

[rfarina]

@lcrespom, that's funny. I ONLY get it in the angular-cli versions :) As an update, I found that by commenting out the @Injectable() method, the squiggly lines go away and the code still runs. It's almost as if it's just not needed.

[rfarina]

@lcrespom @M4ttsson With both your help and the suggestion of @M4ttsson, I modified the vs code workspace settings for the typescript location. By default it is set to "null". I set it to the following, reloaded vs code, and all seems to be working as expected with both Decorators and Promise, etc.

"typescript.tsdk": "./node_modules/typescript/lib"

Installing angular material design but this issue

[Ehasaniceiu04]

I am facing this kind of issue

[jay12gore]

Issue : @angular/compiler-cli@5.0.2 requires a peer of @angular/compiler@5.0.2 but none was installed

Solution to Above issue is

1. Go to package.json file and change the version of compiler-cli from "@angular/compiler-cli": "^5.0.0",to "@angular/compiler-cli": "^5.0.2",

[vargalas]

Yeah, develop your in-house solution instead.
