JavaScript heap out of memory

[Daniel4Digital]

Can't run "npm run dev" with .purgeCss({ enabled: true }) (if I put false it works perfectly)

I was using an older version of laravel-mix-purgecss (0.1.2 I guess) and older version of laravel-mix and postCCS etc, the problem happened back then too. I update all packages to last version, so now I'm using:
"laravel-mix": "^6.0.5",
"laravel-mix-merge-manifest": "^2.0.0-beta.2",
"laravel-mix-purgecss": "^6.0.0",

My project uses laravel + vue.

This is the error, any idea why (Not sure if the problem is from this plugin)?

I was using 6Gb, I've given the docker 8Gb and put node with 8gb aswell, and now it worked. We can close this.
