This is more likely an issue with yarn itself. Does it happen only when trying to add this plugin? If you try to install other webpack plugins, you don't see the same result?

If the issue is only with PurgeCSS plugin, could you provide a repository to reproduce this issue?

[teekenl]

@Ffloriel thanks for the quick response! It happened even when you installed it with npm. And yes, it only happened when trying to add this. This is my very basic repo https://github.com/teekenl/test-purge-css, so if you pulled down and run yarn install before trying to run yarn add purgecss-webpack-plugin you will get the error.

Hey @teekenl - did you ever find the solution?

Unsure if it's because of a new version of Yarn but the issue seems to not happen anymore in https://github.com/teekenl/test-purge-css
