• this is a screenshot : this question may be duplicated . but I tried most of answers and not works for me

Answer 1

use

c:>npm cache clean

c:>npm delete proxy

and try again

Answer 2

The screenshot is not the same as what you wrote in your question.

In the question you quote:

npm ERR! network getaddrinfo ENOTFOUND ex-proxy.com ex-proxy.com:8080

What's vsible in the screenshot is:

npm ERR! network getaddrinfo ENOTFOUND registry.npms.org registry.npms.org:80

It should be registry.npmjs.org and not registry.npms.org.

Compare:

• http://registry.npms.org/
• http://registry.npmjs.org/

If you're using a proxy then you should configure it properly. If you can access https://registry.npmjs.org/ from your computer directly and you can ping registry.npmjs.org then you should not need a proxy.

Answer 3

I managed to solve it

this problem happened because

1. Visual Studio not installed
2. Some issues with internet connection
