async-each | code async parallel forEach / map function | Reactive Programming library

I have resolved this issue with below steps :

1. make sure you have internet connection: ping 8.8.8.8
2. make sure you have DNS resolver working: ping www.google.com
3. make sure you can access registry.npmjs.org: ping registry.npmjs.org
4. make sure you can connect via https.

Run below command in npm command prompt or Visual Studio Code terminal.

npm config rm proxy

npm config rm https-proxy

Try in your browser: https://registry.npmjs.org/

Make sure you are trying to connected to:

registry.npmjs.org

and not to:

"registry.npmjs.org registry.npmjs.org:443"

Use below command to set registry.

npm config set registry https://registry.npmjs.org/

If you are using a proxy to access the Web, then you also have to configure npm to use it. Use:

npm config set proxy http://username:password@proxyname:8080

npm config set https-proxy http://username:password@proxyname:8080

Points to remember here while setting above two values :

1. proxyname you need to check with your company network team. Enter that proxy URL in above 2 values.
2. If your password contains any special character then replace it with Encoded character. In this command you can’t provide a password with special character. Replace only special character not .(dot).

   Example: password is : Welcome@12# then it will be like Welcome%4012%23.

Then try to run your npm install command and it should work.
