Unable to npm install Angular-cli after proxy configuration

Question

I am trying to download Angular in Windows 10 using npm install. As I am on corporate proxy, I configured the proxy to username:password@server:port

However, I am facing this issue when running

npm ERR! code E407 npm ERR! 407 Proxy Authorization Required: @angular/cli@latest

The debug log as followed:

Any idea what could have cause the issue? Thanks!

Answer 1

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/

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

npm config set proxy http://user1:01xx%[email protected]:8000/
npm config set https-proxy http://user1:01xx%[email protected]: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
proxy=http://user:password@domain_proxy:port/
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:

proxy=http://user1:[email protected]:8000/
https-proxy=http://user1:[email protected]:8000
