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,

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

    How do I then remove these settings? – theonlygusti Feb 06 '16 at 11:19

    @theonlygusti You don't need to remove them as these settings are only active within a command prompt window. If you close your command prompt window and reopen it you'll find out that you need to reenter the commands for it to work. – Anwuna Feb 09 '16 at 13:22

    If want to clear the settings and don't want to close command prompt, use the following commands "set http_proxy=" and "set https_proxy=" – Aron Curzon Feb 10 '16 at 20:57

  • ok and how do I display the currently set proxy? echo %HTTP_PROXY% does nothing – McVitas May 09 '17 at 18:56
  • Also you can see actual environment proxy vars with: set http_proxy . If isn't setted it'll appear "Environment var http_proxy not defined. – albertoiNET Jul 12 '17 at 13:47
  • If also fetching from an internal location It's sometimes necessary to also set `no_proxy` to bypass the proxy for those subdomains / IP addresses. Note that parsing/behaviour around the `no_proxy` list is application-dependent and frequently inconsistent. – Ed Randall Oct 13 '21 at 08:52

You need to write this in the command prompt:

set HTTP_PROXY=http://your_proxy:your_port

You need to add http_proxy and https_proxy environment variables as described here.

  • Thanks, @TylerH. I checked on my personal laptop, and there was probably something about the fancy formatting that couldn't render in our enterprise – Ion Freeman Dec 24 '18 at 02:12

When setting http_proxy and https_proxy, you are also probably going to need no_proxy for URLs on the same side of the proxy. https://msdn.microsoft.com/en-us/library/hh272656(v=vs.120).aspx

In Addition to @Yifei answer. If you have special character like @, &, $

You have to go with percent-encode | encode the special characters. E.g. instead of this:

http://foo:B@r@http-gateway.domain.org:80

you write this:

http://foo:B%40r@http-gateway.domain.org:80

So @ gets replaced with %40.

You can try export http_proxy=http://your_proxy:your_port

None of the answers here actually helped my case (proxy + password), instead I found a solution on a Github issue:

https://github.com/rubygems/rubygems/issues/1068

Basically I had to set three variables:

set http_proxy=proxy_ip:port
set http_proxy_user=user
set http_proxy_pass=password
