Laravel-mix: Npm run hot fails with copy ()

[skyronic]

Sample mix config:

This works with npm run hot

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

This doesn't work with npm run hot and fails with unspecified error

mix.js('resources/assets/js/app.js', 'public/js/app.js')
   .sass('resources/assets/sass/app.scss', 'public/css/app.css')
   .copy ('resources/tmp', 'public/tmp'); 

 ERROR  Failed to compile with 1 errors

 error

OS: Windows 10
Nodejs: v6.9.5
Yarn: yes
Npm: yes

I have this issue too.
@skyronic which OS are you using? It might be a Windows problem?!

Running npm run dev does work properly. I already tried to copy single files and directories.
Also when I try to both relative and absolute paths it simply does not work.

The error message is not descriptive at all.
Does anyone has a clue where the error is comming from?

@ArjanSchouten I am on Mac OS. Yeah, copying works great on npm run dev. Currently I'm using mix for hot reload and gulp for copying. HMR and Mix's speed is totally worth the temporary inconvenience though.

In my current project, also fails with npm run dev, like @skyronic

same problem

[TiBianMod]

OS: macOS Sierra 10.12.4
Nodejs: v7.9.0
Laravel-Mix: v0.10.0

same problem here with npm run hot.

Both methods mix.copy() & mix.copyDirectory() reproduce an error.

same issue over and over again :(

+1, same issue. Windows 10x64, node 6.9.5

Temporary solution disable mix.copy when you running npm run hot

if (! mix.config.options.hmr) {
    mix.copy('path/from', 'path/to');
}
