Hi, I am trying to develop a web app using .net core angular 2 but I am having trouble running the app

Call to Node module failed with error: TypeError: Cannot read property 'publicPath' of undefined

Any Idea why this issue is popping up. By the way, i am using webpack 2

Are you using the latest generator here? What changes have you made since the original? Check your git history on the webpack.config file its something there causing it potentially.

WebpackDevMiddleware tries to read publicPath from the output section of your Webpack config. If you (somehow) don't have an output section, you'd get this error. I don't think your Webpack config is likely to work without an output section anyway, so you probably should compare your config with a working one.

If you think there are scenarios where you wouldn't have an output section but this should still work, please file a separate issue with details. Thanks!

@SteveSandersonMS @MarkPieszak Thank you. Actually i found the issue. It's because I have another node modules list were installed inside my user folder. I have removed that folder and it started working.
