EISDIR: illegal operation on a directory, read

[val-bubbleflat]

Trying to use laravel-mix-purge-css, I have this error message running npm run prod :

this is my webpack.mix.js

mix.webpackConfig({
    plugins:
        [
            new WebpackShellPlugin({onBuildStart:['php artisan lang:js resources/assets/js/traduction/messages.js --no-lib'], onBuildEnd:[]}),
            new LiveReloadPlugin(),
        ],
});

mix.js('resources/assets/js/app.js','public/js')
    .sass('resources/assets/sass/app.scss', 'public/css')
    .options({ processCssUrls: false })
    .purgeCss();

if (mix.inProduction()) {
    mix.version();
}

as in #2, I just upgrade from laravel-mix fom 0.* to 2.0.0 to use this package

Hope somebody can help :) Val

Please do a fresh install of all of your dependencies (including global).

[mboisvertdupras]

Doing a fresh install of project & global packages hasn't helped me personally. I've tested with both npm & yarn and Node v8.11.1 through v10.1.0.

The problem seems to be project specific. The same setup works in another directory for me.

[cjmaxik]

What is your exact environment? I am pretty much sure this is a directory rights problem, not a bug.

require('laravel-mix-purgecss')

mix.webpackConfig(webpack => {
  return {
    plugins: [
      new LodashModuleReplacementPlugin()

mix.js('resources/assets/js/app.js', 'public/js')

    .version()
    .browserSync('eternity.test')

I had the exact same error, but after some digging the problem in my case was because of a folder ending in '.js'.

I suspect that purgecss or laravel-mix-purgecss searches for everything ending with the extensions defined in the config, including css, js, etc. In my case that also returned a folder -- purgecss only works on files and throws this error.

To see the folder that throws an error you can temporarily add a console log in node_modules/purgecss/lib/purgecss.js on line 645, change:

var file = _step6.value;

var content = fs.readFileSync(file, 'utf8');

to:

var file = _step6.value;

if (fs.lstatSync(file).isDirectory()) {
  console.log(file);
}

var content = fs.readFileSync(file, 'utf8');

Rename the folder(s) that gives problems, and rename it.

Not the best solution, but it solves the problem for now. I'll see if there's a possibility for changing the glob matching to only match files, and not folders.

36 should have fixed this. Feel free to reopen if anyone still has issues.

I still have this problem when trying to use laravel-mix-purgecss in production builds. Here is my error message:

Here is my webpack.mix.js:

const mix = require('laravel-mix')
require('laravel-mix-purgecss')
require('mix-tailwindcss')

mix.ts('resources/js/app.ts', 'public/js')
   .sass('resources/sass/app.scss', 'public/css')
   .tailwind()

if (mix.inProduction()) {
  mix.purgeCss()
     .version()
}

Nevertheless, laravel-mix-purgecss works correctly in my development builds, and my production builds work correctly if I remove mix.purgeCss() from webpack.mix.js.

UPDATE: It seems this problem affects version 5.0.0-rc.1 only. I've downgraded laravel-mix-purgecss to version 4.2.0 and it seems working correctly now.
