}

ng build -prod was working fine, however all of a sudden the same configuration gives the following error

ERROR in ./src/styles.css
Module build failed: Error: Cannot find module '/Volumes/DATA/new-    clone-test/nbw/node_modules/css-loader/index.js?sourcemap&minimize'
at Function.Module._resolveFilename (module.js:440:15)
at Function.Module._load (module.js:388:25)

at require (internal/module.js:20:19)
at loadLoader (/Volumes/DATA/new-clone-test/nbw/node_modules/loader-runner/lib/loadLoader.js:13:17)

I am not sure what causes this issue. Any help will be much appreciated.

Answer 1

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'.

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",
       ...
   }
}
