bug: No Entry found & argument error

[webpack-bot]

Bug report

What is the current behavior?
It fails to build and shows this:

cross-env NODE_ENV=production webpack --mode production --progress --hide-modules

[prerender-spa-plugin] You appear to be using the v2 argument-based configuration options. It's recommended that you migrate to the clearer object-based configuration system.
Check the documentation for more information.
                                                                          
Insufficient number of arguments or no entry found.
Alternatively, run 'webpack(-cli) --help' for usage info.

ERROR in Entry module not found: Error: Can't resolve './src' in '/home/maxie/Dropbox/Public/Learning/VueJS/vue-static'
Child html-webpack-plugin for "index.html":
     1 asset
    Entrypoint undefined = index.html

If the current behavior is a bug, please provide the steps to reproduce.

What is the expected behavior?
It should build the application successfully like how it was done here which worked until the warnings messages which got me to update the plugins and the config to what can be found in this repo.

Other relevant information:
webpack version: 4.16.5
Node.js version: 10.7.0
Operating System: ArchLinux x64 (Linux 4.17.11.a-1-hardened)
Additional tools: webpack-cli@3.1.0, webpack-dev-server@3.1.5

This issue was moved from webpack/webpack#7874 by @montogeek. Original issue was by @Berkmann18.

Hi @Berkmann18 . You'll need to do --entry=foo.bar

[Berkmann18]

@ev1stensberg Okay, so the entry property was removed. Thanks for letting me know.

[evenstensberg]

That might come of you using cross-env. First argument is your environment in cross env. Try without cross env just to test that it works. The entry property havent been removed.

I'm now getting this error:

NODE_ENV=production webpack --mode production --progress --hide-modules --entry=./src/main.js

          return context

      }),
      new VueLoaderPlugin()

}

I tried looking at how the VueLoaderPlugin was supposed to be used after getting an error related to webpack not finding that loader and I think I did that bit right but webpack seems to not like that.

[evenstensberg]

Could you post a repro in a seperate repository?

[Berkmann18]

Would that be better than committing what I have now without the old configuration?

[evenstensberg]

It would make it easier for us to debug

[Berkmann18]

Okay, I'll do that then.
I deleted the other one and made a new repo.

[evenstensberg]

Thanks! Will check it out during the week! Ping me friday if I haven't given you a response!

[Berkmann18]

Okay, I'll do.
