I have no idea why is this happening, i am using vagrant and virtual box but this compiles on my machine not on the virtual one.I get this "Unknown error" on random files.
What i have tried:
Remove/Reinstall node_modules
Upgrade Node and NPM
Clear NPM cache
OS: Windows 7
Laravel: 5.4v
NPM: 5.5.1v

Answer 1

You can try removing node_modules folder and run again
npm install

Answer 2

In my case the output directory was corrupted and could not be opened anymore, so webpack could not access it.
Working around that by checking out the project in another location was the fastest solution, as deleting the directory was not easy and required repairing the drive with the windows repair tool (Right-Click in File Manager on Drive -> Properties -> Tools -> Disk Check).
