npm Unable to Install angular-cli - angularjs

Question

I am trying to install angular-cli via npm. I have the recent version of Nodejs and git installed. I am not behind any proxy server(verified it through netsh winhttp show proxy as well as through Internet Explorer LAN settings) and there is no problem with my internet connection. When i try to run
npm install -g angular-cli then I get the following error
C:\Windows\system32>npm install -g angular-cli
npm ERR! Windows_NT 6.1.7601

I tried cleaning the cache through npm cache clean and also tried to change the registry to http:\ via
npm config set registry http://registry.npmjs.org/
I also tried uninstalling nodejs and reinstalling it again but it is not working. I am getting the same error. Any ideas.

Answer 1

Setp-1: open windows command prompt then type following command to get the IP address of your proxy server
ping your-proxy-name
For example:
ping myproxy.xyz.com
Step-2: open Node.js command prompt and type following command
npm config set http-proxy http://your-proxy-ip-retrieved-in-step-1:port
npm config set https-proxy http://your-proxy-ip-retrieved-in-step-1:port
For example:
npm config set http-proxy http://192.168.192.95:8080
npm config set https-proxy http://192.168.192.95:8080
Setp-3: on Node.js command prompt type following command to install angular
npm install -g #angular/cli
Hope it will work for you.

Answer 2

Yes, this can be caused either by a firewall or a proxy. Can you ping the npm registry host and fetch a simple file?
> ping registry.npmjs.org
> npm view npm version
If the ping is not successful, check your connection or disable your firewall.

Answer 3

Future viewers: Try below approach (it worked for me)
Go to nodejs installed location (path may be different in your case)
C:\Program Files\nodejs\node_modules\npm
Add below entry in the npmrc file then save it
strict-ssl=false
Then try installing angular cli
npm install -g #angular/cli

Answer 4

This kind of issues usually happen when you are behind a proxy or a firewall that blocks npm from fetching the requested packaged.
If you know your proxy address and port, open a console and set your HTTP_PROXY and HTTPS_PROXY variables before running npm, as follows:
set HTTP_PROXY = "http://<proxy server name or IP address>:<proxy port>"
set HTTPS_PROXY = ... ;same as above
npm install <package_name>

Answer 5

I faced similar issues and figured that we need to combine the proxy and the install command together like below and it worked for me. Hope it works for you people. Thanks!!
npm --proxy http://username:password#proxyURL:port install -g #angular/cli --without-ssl --insecure

Answer 6

You need to override your proxy settings to install angular CLI.
Try executing below command :
npm config set registry http://registry.npmjs.org/
This will override your proxy and you do not need to make any changes to your connections or firewall. Once this command executes successfully try installing angular CLI using below command:
npm install -g #angular/cli
Refer this link for more details on this.
This solved problems for me. Hope this helps!
