Express JS install

I was trying to install expressjs.

I keep getting this error here :

 node.js:201
        throw e; // process.nextTick error, or 'error' event on first tick
              ^
Error: No such module
    at Object.<anonymous> (/usr/share/npm/lib/utils/output.js:8:21)
    at Module._compile (module.js:432:26)
    at Object..js (module.js:450:10)
    at Module.load (module.js:351:31)
    at Function._load (module.js:310:12)

    at Module._compile (module.js:432:26)
    at Object..js (module.js:450:10)

any idea why that error is occurring. I installed npm there doesnt seem to be any problem with that.

this is the command I try to use for installing express js :

sudo npm install express -g

I tried with the guide on the expressjs website as well. Sorry, my bad. dint install latest version of nodejs
