Node js Error Cannot find module express

0 votes

I have written a code for my Nodejs app but when I run it, it's not able to find the express library.

C:\ChatServer\Server>node server.js

module.js:340
    throw err;
          ^
Error: Cannot find module 'express'
    at Function.Module._resolveFilename (module.js:338:15)

    at Function.Module._load (module.js:312:12)

I have already installed the library with -g key:
