cannot find module css-loader while doing ng build -prod with angular-cli@1.0.0-beta.21

Question

I have following package.json configuration

\"dependencies\": {
\"@angular/common\": \"2.2.1\",
\"@angular/compiler\": \"2.2.1\",
\"@angular/core\": \"2.2.1\",
\         


        

Answer 1

had the same issue starting today.

The solution I found was to change the angular-cli dependency in package.json file to "1.0.0-beta.19-3" and reinstall the npm packages.

{
  "devDependencies": {
       ...
       "angular-cli": "1.0.0-beta.19-3",
       ...
       }
}

Hope this helps!

Answer 2

mkishorem is right.

I also got same error and fix with adding override code at package.json like below

"devDependencies": {
 "extract-text-webpack-plugin": "2.0.0-beta.5" 
 }

no need to downgrading to angular-cli all.

Answer 3

Update to @angular/* 2.3.1 version

Answer 4

Thanks to Florinache!

Downgrading to angular-cli "1.0.0-beta.19-3" works for me. I had the same issue from today on in all my projects...

{
  "devDependencies": {
       ...
       "angular-cli": "1.0.0-beta.19-3",
       ...
   }
}

Answer 5

I have got the same issue as you. As a temporary solution I changed to 'ng build --dev'. Using this command the loader uses webpack-build-development.js instead of webpack-build-production.js and gets 'css-loader?sourcemap' instead of 'css-loader?sourcemap&minimize'.

Answer 6

It looks like extract-text-webpack-plugin is upgraded to RC, Try overriding the extract-text-webpack-plugin version to "2.0.0-beta.4" in your package.json.
