Update your cross-env and see if it works?

It's now 5.0.0 while yours is still at 3.2.4

[lotestudio]

Nope :(

[msonowal]

same here just installed

npm run watch works fine but
npm run prod throws error

```
cross-env NODE_ENV=production node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js

95% emitting

ERROR Failed to compile with 4 errors

error

/js/_users.js from UglifyJs

Unexpected token: punc (() [/js/users.js:48382,11]
```

[msonowal]

@lotestudio
I fixed it by adding this to a newly created file .babelrc
{"presets": [ ["env", { "targets": { "uglify": false } }] ]}

[adiachenko]

Do you use Yarn or npm shrinkwrap by any chance?

It may be that some locked dependencies haven't updated properly. Try to delete node_modules folder and then do simple stupid npm install.

I had ELIFECYCLE error after upgrading to 0.12, Then if I recall correctly I performed the following sequence of actions:

yarn remove laravel-mix
yarn add laravel-mix
yarn remove cross-env
yarn add cross-env

Weirdly, the issue was gone after purging the old cross-env.

[lotestudio]

@adiachenko I use npm, but will try the sequence.
@msonowal same with with watch and production.

[lotestudio]

Hm...I've found that laravel notification in upper right corner produce warning: 'undefined/app.someversioncontrolnumber.js'.
Here is my webpack.mix.js:

const {mix} = require('laravel-mix');

mix.setPublicPath('public_html/');

mix.js('resources/assets/js/app.js', '/js')
    .sass('resources/assets/sass/app.scss', '/css')
    .sass('resources/assets/sass/pdf.scss', '/css');

mix.browserSync('jobs');

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

[lotestudio]

The vue-strap library caused the problem. There is some files that babel can't compile for some reason. I've complied them manually with babel online compiler and everything work now. Still don't understand the problem entirety. The errors in command line is not so clear, but notification panel from laravel mix show me the exact error. Is there some explanation why mix can't compile these files?

[LorrainInfinity]

Hi @lotestudio . Did you find any answer to your question "Is there some explanation why mix can't compile these files?" ? Because I ran into the very same problem (for another vue npm package but basically the same problem). I'm pretty sure that if I change the file by hand to make it readable in JS it'll work but I'd prefer not to touch to npm dependencies in my project and I can't figure out how to solve this O_O

@msonowal after spending hours and hours and hours with this issue, your solution fixed everything like a charm! Thanks a lot!
