Repro steps.

Was this an app that wasn't created using the CLI? What change did you do on your code? etc.
Created a brand new app
Added latest @angular/material and added it to app.module
ng serve runs fine.
Ran ng eject to expose webpack.config
Now running npm start creates the error below

Same problem occured to me yesterday - haven't found any solution yet.

Possibly related: mozilla/source-map#247

[ScallyGames]

As a quick workaround setting "devtool": "eval" in webpack.config.js makes the build run again.

However a proper solution is needed.

[kamalkech]

@Aides359 : i can't find webpack.config.js in root folder of project

[thecameraguy]

@kamalkech 'ng eject' should have generated webpack.config.js at your root.

I am having this exact issue as well.. Trying to override the default url-loader for .cur and .ani files and I thought I found the solution with ng eject but alas.... hopefully this issue is the last hurdle..

[jackytse]

Don't write two or more classes in the same ts file. I think it's a bug of 'source-map'.

[ScallyGames]

I am 100% sure that I have no file with more than one class in it.
If anything it is a problem with import/export and not with class declarations.

[jackytse]

Maybe you can try this solution.

We have exactly the same problem but only with Windows 7. Under macOS 10.12 it's working fine. Is there a satisfying solutions yet?

CLI 1.0 prerelease versions are no longer supported. If this error still occurs on the latest version (6.1.4 currently). Please open a new issue describing the problem.
