Issue with `sass-loader` (this.getResolve is not a function)

[ngryman]

Hey folks,

I've facing the following issue with sass-loader:

Error Details

ERROR in ./app.scss (./node_modules/thread-loader/dist/cjs.js!./node_modules/css-loader/dist/cjs.js!./node_modules/sass-loader/dist/cjs.js!./app.scss)

When I remove thread-loader from the loaders chain, it works correctly. Here is a very simple repo to reproduce that issue: https://github.com/ngryman/thread-sass-loaders-bug.

I've also already surfaced that issue in the sass-loader repo as I'm not sure which package is buggy.

Yes, feel free to send a PR

Should be very easy to fix

[ngryman]

@evilebottnawi I'd be glad to open a PR but unfortunately I'm not very familiar with thread-loader or Webpack's internals. Could you provide me with some help so I can open that PR? Thanks.

https://github.com/webpack-contrib/thread-loader/blob/master/src/index.js#L23 just add getResolver: this.getResolver should be work

[rainke]

I use MiniCssExtractPlugin.loader still has the error

[rainke]

should add getResolve in here
https://github.com/webpack-contrib/thread-loader/blob/master/src/worker.js#L120

Encountered the same problem, maybe you can look at this issue:
webpack/sass-loader#761 (comment)

The same error occurs for less-loader 6.0.0.
