Below are some of the errors that I have encountered while installing npm using Node.js on Windows 8.
Error: ENOENT, stat 'C:\Users\[CurrentUser]\AppData\Roaming\npm'
This error occurs because Node.js Windows Installer has a bug as it is not able to create ‘npm’
folder under the user’s roaming profile .
You can fix this by creating a folder “npm” under C:\Users\[CurrentUser]\AppData\Roaming\

This occurs because you dont have permissions to install npm and you are probably accessing
it behind a corporate web proxy.
Set the proxy config for Node.js.
npm config set proxy http://proxy.company.com:8080
npm config set https-proxy http://proxy.company.com:8080
If you are using network username and password for the proxy, then use the below configs
npm config set proxy http://user_name:firstname.lastname@example.org:8080
