How to resolve code ERR_INVALID_URL in Angular-cli installation

Question

In my windows-10, I installed:

nodejs-v16.13.0

npm -v8.1.0

When I tried to run npm install -g @angular/cli

I got this error:

npm ERR! code ERR_INVALID_URL

npm ERR! Invalid URL

How do I get this resolve?

Thanks

Answer 1

I just reconfigure proxy using this command:

npm config set proxy http://username:password@host:port 

and it worked!

Answer 2

Generally there is a log file associated with this message :

npm ERR! code ERR_INVALID_URL
npm ERR! Invalid URL

npm ERR! A complete log of this run can be found in:
npm ERR!     C:\Users\....\AppData\Local\npm-cache\_logs\2021-11-04T09_13_08_065Z-debug.log

You can see more details in this file. I had the same problem, in my case I simply omitted the "http://" when I initially set up the proxy :

npm config set proxy "http://127.0.0.1:3128/"
             here !!! ^^^^^^^

For reference, it failed with this trace :
