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

Solved it. After I spent a bit of time on proxy issues, it turns out my mistake was setting 3 proxy variables: proxy, http-proxy and https-proxy.

(note: I read somewhere on stackoverflow that I was supposed to set http-proxy but this is wrong)

Removing http-proxy solved this for me.

Setting npm proxy and npm https_proxy is correct, as follows:

npm config set proxy http://user:password@proxy.companyname.com:port/
npm config set https-proxy http://user:password@proxy.companyname.com:port/

Answer 2

To config proxy in office,

npm config set proxy http://user:password@proxy.companyname.com:port/
npm config set https-proxy http://user:password@proxy.companyname.com:port/

Answer 3

The thing that worked for me as below, Issue: Registry defined at "C:\Users*user-name*.npmrc" was wrong. Need to update npm config registry.

Step 1 Solution: Removed registry entry from "C:\Users*user-name*.npmrc" file.

Step 2 After Step 1 I got below error

npm install -g @angular/cli npm WARN registry Unexpected warning for https://registry.npmjs.org/: Miscellaneous Warning SELF_SIGNED_CERT_IN_CHAIN: request to https://registry.npmjs.org/@angular%2fcli failed, reason: self signed certificate in certificate chain npm WARN registry Using stale package data from https://registry.npmjs.org/ due to a request error during revalidation.

Issue: The npm maintainers announced on February 27th that npm’s Self-Signed Certificate is No More: A bunch of users received a “SELFSIGNEDCERTINCHAIN” error during installing and publishing packages throughout the day today. npm no longer supports its self-signed certificates. However, the recommended fix failed for me.

Solution: Open command prompt, and run below commands. SETLOCAL SET npm_config_strict-ssl=false npm install npm -g --ca=null npm --version ENDLOCAL

Step 3 Now >npm install -g @angular/cli running all ok.

Answer 4

This steps worked for me

Edit .npmrc file add below lines

proxy=http://username:password@proxyaddress:portno
https-proxy=http://username:password@proxyaddress:portno

Answer 5

If you have configured Proxy and Still you are not able to install using npm command. You can try below command. It seemed you need to clear some stuff - and that will fix the issue.

npm cache verify

Answer 6

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%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
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://user1:01xx!tr@mydomain.org:8000/
https-proxy=http://user1:01xx!tr@mydomain.org:8000

Answer 7

Try making the URL of npm registry to http instead of https. You can take a look at this answer.
