如何为gem设置代理服务器？

Question

我无法通过命令提示符安装SASS.

我试过以下步骤

c:\gem install sass

我收到以下错误:

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)

请帮我,

Answer 1

对于带或不带身份验证的http/https代理:

在cmd.exe中运行以下命令之一

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

您需要在命令提示符下写入此内容:

set HTTP_PROXY=http://your_proxy:your_port

Answer 3

您需要添加http_proxy和https_proxy所描述的环境变量这里.
