Any idea what could have cause the issue? Thanks!

This configuration worked for me :

method1 (command line):

npm config set proxy http://user:password@domain_proxy:port/
npm config set https-proxy http://user:password@domain_proxy:port

be careful the url should be encoded. for example this password 01xx!tr should be introduced as 01xx%21tr. use this site to encode your url https://www.url-encode-decode.com/

user/password => user1/01xx!tr
domain:port of the proxy => mydomain.org:8000
=> in that case :

npm config set proxy http://user1:01xx%21tr@mydomain.org:8000/
npm config set https-proxy http://user1:01xx%21tr@mydomain.org:8000

method2 (edit node conifugration file):

the method 2 is easier because we will not be botherd with encoding the urls

1- edit node configuration file (in windows it's located in %USERPROFILE%\.npmrc, example C:\Users\Jack\.npmrc)

2- add these lines
https-proxy=https-proxy http://user:passwor`enter code here`d@domain_proxy:port

example :
if the :
user/password => user1/01xx!tr
domain:port of the proxy => mydomain.org:8000

=> the configuration file should be look like this:

  • use this solution. it worked for me.
  • use this solution. it worked for me.
  • Can you put the log file here of the error that is shown after you change it to http ?
  • [reason: getaddrinfo EAI_AGAIN .:80] Indicates that there is a DNS resolution issue. Please check the proxy & port of your corporate proxy configuration. Many uses 8080 as port of proxy.
  • Have changed the port to 8080, the error i have gotten is the same as what I have previously. Thank you
  • Basically you need to check the proxy port configured for your corporate network. 8080 might not be the port of your corporate proxy. Any how, this is a DNS resolution issue of npm.
