Error: EISDIR: illegal operation on a directory

Hello, I try to install purgecss-webpack-plugin on my stack but I get the following error :

/Volumes/APPLE SD Card/Projets/beapi/beapi-frontend-framework/themes/beapi-frontend-framework/node_modules/purgecss-webpack-plugin/node_modules/purgecss/lib/purgecss.js:674
                        throw _iteratorError5;
                        ^

Error: EISDIR: illegal operation on a directory, read

You can reproduce the issue by cloning the repo : https://github.com/BeAPI/beapi-frontend-framework/tree/experiment/purgecss

$ npm install
$ npm run build:test

Version of purgecss-webpack-plugin : 1.2.0

Hey, did you manage to fix the issue? I can't see purgecss-webpack-plugin in your repo

Hello @jsnanigans ! Nope, I didn't find a way to fix this issue. What do you mean by "I can't see purgecss-webpack-plugin in your repo" ? I installed the node package as devDependency : https://github.com/BeAPI/beapi-frontend-framework/blob/experiment/purgecss/package.json#L66

You likely need to pass {noDir: true} as an option to glob.sync() as glob.sync is matching a dir which the plugin can't operate on.

new PurgecssPlugin({
  paths: glob.sync(`${paths.appSrc}/**/*`)
}),
// becomes
new PurgecssPlugin({
  paths: glob.sync(`${paths.appSrc}/**/*`, { nodir: true })
}),

I ran into this issue as well. Passing nodir worked.
