Usually I can install a library using npm but today when installing yeoman I encountered this errors. Please help to figure out what's root cause.
D:\Works\phonegap\ionic\todo>npm install -g yo
module.js:340
throw err;

Error: Cannot find module 'C:\Program Files\nodejs\node_modules\npm\bin\node_modules\npm\bin\npm-cli.js'
at Function.Module._resolveFilename (module.js:338:15)
at Function.Module._load (module.js:280:25)

I looked into the folder:
C:\Program Files\nodejs\node_modules\npm\bin\
but don't see node_modules folder as the error described.
I also try to find npm-cli.js and see it's actually in C:\Program Files\nodejs\node_modules\npm\bin\
It turns out the issue is due to wrong path of node in system variable. The path is currently point to (I really don't know when I modified it)
C:\Program Files\nodejs\node_modules\npm\bin
so I change to
C:\Program Files\nodejs
and it works like a charm.
You may also have this problem if in your path you have C:\Program Files\nodejs and C:\Program Files\nodejs\node_modules\npm\bin. Remove the latter from the path
On a Mac:
I was running this out of the Maven com.github.eirslett Frontend Plugin when I had the same error.
Eventually I had to:
Install Node.js via the installer download here: http://nodejs.org/
Delete all the node/ and node_modules/ folders from within my maven build structure.
