Steps to reproduce

Init a project without installing webpack locally , and run global webpack in terminal

Error: Cannot find module 'webpack/lib/RuleSet'

Due to line 2 in node_modules/vue-loader/lib/plugin.js

const RuleSet = require('webpack/lib/RuleSet')

@935839596 webpack already added as a peer dependency in the latest version. Now there should be a warning if you didn’t manually install webpack alongside vue-loader.

I had to add the following to webpack.config.js to get around this error:

var webpack = require('webpack');

[BoyaZhang]

add webpack package to ur package.json, cause vue-loader is based on it

Any updates?

Adding webpack as a dev dependency resolved the issue for me.

This happens with the next version of Webpack (Webpack 5.0.0-rc.1)

It has to be webpack ^4.0.0 as the file was removed in v5.

"has to"... well, if we have packages that depends on webpack5, we can't really ask them to use a downgraded version though

[sodatea]

Both v15 & v16 have already added support for webpack 5. So if you still encounter this issue, please open a new issue with a minimal reproduction.

FYI, this was the only relevant search result when I also encountered the error you mentioned @hieutranminh in a Nuxt project. So in case anyone else out there is also trying to use Webpack 5 with Nuxt, it's a matter of @nuxt/components not yet supporting webpack5, and we can move that discussion over there: https://github.com/nuxt/components/issues/105

Oh yes, sorry, I only added my comment to help those getting dropped off from search engines.
