I can't install gulp-sass module in my gulp project

Question

I do it one month ago, but now I come across with next problem. I tried to reinstall nodeJs. I installed gulp-scss extension, but it didn't install to. And now all extensions installing longer than usually. 1 package installing during for 20 minutes, internet connection is good..

Hint: If github.com is not accessible in your location
      try setting a proxy via HTTP_PROXY, e.g.

      export HTTP_PROXY=http://example.com:1234

or configure npm proxy via

      npm config set proxy http://example.com:8080
