Error when running npm start?

Question

Node.js

I try to start the server with npm start

npm ERR! not ok code 0
npm ERR! weird error 1
npm WARN This failure might be due to the use of legacy binary "node"
npm WARN For further explanations, please read
/usr/share/doc/nodejs/README.Debian

I found a way on the Internet:
sudo apt-get install nodejs-legacy
but I already have nodejs-legacy installed.

Answer 1

On the screen you can see that you have some kind of exception popping up. Unfortunately, it is not clear which one, so it is difficult to suggest something. BUT

This failure might be due to the use of legacy binary "node"

npm always shows when something called returned a non-null code.
