For http/https proxy with or without authentication:
对于带有或不带有身份验证的 http/https 代理：
Run one of the following commands in cmd.exe
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

In Addition to @Yifei answer. If you have special characterlike @, &, $
除了@Yifei 的回答。如果你有@、&、$ 等特殊字符
You have to go with percent-encode| encodethe special characters. E.g. instead of this:
你必须使用百分比编码| 对特殊字符进行编码。例如，而不是这样：
http://foo:B@[email protected]:80
you write this:
你这样写：
http://foo:B%[email protected]:80
So @gets replaced with %40.
所以@被替换为%40.

None of the answers here actually helped my case (proxy + password), instead I found a solution on a Github issue:
这里的所有答案实际上都没有帮助我的案例（代理 + 密码），相反，我在 Github 问题上找到了解决方案：

Basically I had to set three variables:
基本上我必须设置三个变量：
set http_proxy=proxy_ip:port
set http_proxy_user=user
set http_proxy_pass=password

You can try export http_proxy=http://your_proxy:your_port
你可以试试 export http_proxy=http://your_proxy:your_port

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
在设置 http_proxy 和 https_proxy 时，您可能还需要 no_proxy 用于代理同一侧的 URL。https://msdn.microsoft.com/en-us/library/hh272656(v=vs.120).aspx
