Cannot find module 'socket.io' windows 10

问题

I have windows 10 machine and when I try to run my script it's throw error Cannot find module 'socket.io'

server.listen(8089);
// use socket.io
var io = require('socket.io').listen(server);

回答1:

You'll want to use npm install (from your command prompt) to ensure the socket.io package is installed before use.

npm install --save socket.io

The --save flag will add the given dependency to your application's package.json for easier installation in the future
