How can I set a proxy server for gem?

Question

I am unable to install SASS through command prompt.

I tried below steps

c:\gem install sass 

I am getting below error:

ERROR:  Could not find a valid gem 'sass' (>= 0), here is why:           Unable to download data from https://rubygems.org/ - Errno::ECONNREFUSED: No connection could be made because the target machine actively refused it. - connect(2) (https://rubygems.org/latest_specs.4.8.gz) 

Please help me,

Answer 1

For http/https proxy with or without authentication:

Run one of the following commands in cmd.exe

set http_proxy=http://your_proxy:your_port set http_proxy=http://username:password@your_proxy:your_port set https_proxy=https://your_proxy:your_port set https_proxy=https://username:password@your_proxy:your_port 

Answer 2

You need to write this in the command prompt:

set HTTP_PROXY=http://your_proxy:your_port
