Unable install Gulp using npm in Windows

Question

I am trying to install Gulp using npm in Windows 8 using following command in Command Prompt:

npm install gulp -g

And I am getting following error in the command prompt

C:\windows\system32>npm install gulp -g
npm ERR! Windows_NT 6.3.9600
npm ERR! argv "C:\\Program Files\\nodejs\\node.exe" "C:\\Program Files\\nodejs\\

npm ERR! code EAI_AGAIN
npm ERR! errno EAI_AGAIN
npm ERR! syscall getaddrinfo

npm ERR! getaddrinfo EAI_AGAIN registry.npmjs.org:443

npm ERR! Please include the following file with any support request:

I have set the nodeJs executable file path in the PATH environmental variable. What am I missing here?

Answer 1

I think you have a proxy issue too. Try doing this:

npm config set proxy http://<USERNAME>:<PASSWORD>@<SERVER>:<PORT>
npm config set https-proxy http://<USERNAME>:<PASSWORD>@<SERVER>:<PORT>

Change the values surrounded with <> with your proxy data (if you don't use a username to login just delete that part) and try it.

看起来像代理问题，尝试将其放在您的cmd中：

npm config set registry "http://registry.npmjs.org/"
