Is there a way to make npm install (the command) to work behind proxy?

Question

Read about a proxy variable in a .npmrc file but it does not work. Trying to avoid manually downloading all require packages and installing.

Answer 1

I solved this problem this way:

1. I run this command:

   npm config set strict-ssl false
   

2. Then set npm to run with http, instead of https:

   npm config set registry "http://registry.npmjs.org/"
   

3. Then I install packages using this syntax:

   npm --proxy http://username:password@cacheaddress.com.br:80 install packagename
   

Skip the username:password part if proxy doesn't require you to authenticate

EDIT: A friend of mine just pointed out that you may get NPM to work behind a proxy by setting BOTH HTTP_PROXY and HTTPS_PROXY environment variables, then issuing normally the command npm install express (for example)

EDIT2: As @BStruthers commented, keep in mind that passwords containing "@" wont be parsed correctly, if contains @ put the entire password in quotes
