npm install socket.io
You may receive the following error:
Error: ENOENT, stat 'C:\Users\...\AppData\Roaming\npm'
Mmmm, ambiguous error messages.
Apparently this is a bug in the currently current version of Node.js (v0.10.32) and/or NPM (v1.4.28). The solution is straightforward and just requires creating the above noted “npm” folder within AppData. I’m sure you can figure this out, but copy-pasting is much more fun:
That’s it. You should now be able to execute the NPM command to install Socket.io without any errors. Note you will probably need to run this command with administrative privileges. I didn’t need to run my command line as an Administrator, but I’ve read that you may have to (yes, you, specifically; the Google referred to you by name.)
