npm Unable to Install angular-cli

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

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.

Solution 1

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.

Solution 2

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.

I am not able to ping registry.npmjs.org. The request timed out.

so you have a connection issue

[Badr Bellaj]

i've tried it now and its work on my machine so disable your firewall or check your connection is it okey

[Ram Chandran]

Running npm view npm version resulted in the same error as above. So this could be a firewall issue?

[Badr Bellaj]

possible, are you using a proxy? try to use tracert registry.npmjs.org to check the rooting process

[Ram Chandran]

Thanks. I think the problem was with the connection. I disabled the firewall but it didn't work. Used a different ISP to connect to the internet and now the installation was successful.

This worked for me as my corporate proxy was blocking the npm registry url.

I am happy to know that it worked for you. Thanks for your comment!
