@endel that command worked for me, thanks!

It happens when I run the command inside a node@10 docker container as root. In my machine, it works as expected without the extra -- options.

I'm trying to install colyseus.js client via npm: npm install --save colyseus.js, but it returns an error:

root@04196b313c5a:/usr/src/app/frontend# npm install --save colyseus.js

> colyseus.js@0.10.8 postinstall /usr/src/app/frontend/node_modules/colyseus.js
> npm run -s donate

The module gets never installed and I cannot import it.

Am I doing anything wrong?
