Thanks! We'll be in touch soon.

The fix was reported to be using webpack beta.22. Guess there's your answer.

[richavyas]

According to official doc, I run npm install -g angular-cli@webpack and it installs
"angular-cli": "^1.0.0-beta.11-webpack.8", doesn't matter what version of webpack it's using. Not sure if we should install a specific version of webpack first and then install angular-cli

[ShadowManu]

For now you must. The fix for it is only available on master (yet to be released on npm)

[richavyas]

So I tried this:

• updated local package.json
• uninstalled Webpack
• reinstalled webpack beta 22
• updated complete Node Modules

But, when I run ng serve, it eventually shows Webpack version as Version: webpack 2.1.0-beta.21, doesn't matter my local package.json and even npm list include "webpack": "2.1.0-beta.22".

Absolutely clueless what to do.

[richavyas]

Finally got the ng serve working by doing this:

• go to node_modules/angular-cli
• npm install [email protected] --save

this will update webpack installation in angular-cli and angular-cli will stop picking beta 21 internally.

Hence, closing the issue.

[jtsom]

Why is it insisting on installing beta.21?? The package.json file in the angular-cli folder specifies beta.22? Why should I have to fix their code?
