make: *** [dev] Error 1

I already tried to restart my computer. I have 12+ GB free in RAM, so should be OK.

Checked many related open issues in other projects, also stackoverflow. Nothing seems to help...

[GlenDC]

Tried deleting the node_modules folder, and re-run npm install. Still same error when doing yarn dev...

[GlenDC]

https://www.npmjs.com/package/increase-memory-limit also doesn't seem to be any good, pretty dumb tool that replaces way too much in the node_modules bin dir...

webpack/webpack#1914 (comment) was the comment that finally made it work again for me...
