NodeJS Error - errno EAI_AGAIN

In this post we are going to discuss about errno EAI_AGAIN. You can get this error when trying to install the latest version of npm or trying to install any module.

EAI_AGAIN actually means a temporary failure in name resolution or simply the name server returned a temporary failure indication. It will ask you to try again later. The error will look like :

-------------------------------------
npm ERR! Error: getaddrinfo EAI_AGAIN
-------------------------------------
npm ERR! code EAI_AGAIN
npm ERR! Errorno EAI_AGAIN
-------------------------------------

Accoding to MSDN, getaddrinfo function provides protocol-independent translation from an ANSI host name ti an address. When it is sucess it return zero. Failure retuns a nonzero Windows Sockets error code. The error code are as follows :

PC : https://msdn.microsoft.com/en-us/library/windows/desktop/ms738520%28v=vs.85%29.aspx

EAI_AGAIN is actually a DNS lookup timed out error means it is either a network connectivity error or some proxy related error. Try resolving your proxy settings and check you have a decent internet connection or not. It will resolve your problem, if not try upgrading npm to the latest version ( using npm install npm@latest ), as there might be scenario that you are using older version of npm.
