Error running a nodejs server on a Mac, 'no suitable image found'
Nevermind. Facepalm. The node_modules folder I had was the same that I used/installed in Linux, so I believe that some parts were compiled specifically for Linux, or whatever.
Solved by erasing the node_modules folder and reinstalling.
I hope it helps to anyone with the same doubt!
Follow David Da Silva ContÃn's answer is great!
$ sudo rm -rf node_modules/$ npm install
