ruby - 无法在代理后面安装 ruby​​ gem

Question

我已经配置了我的 http_proxy 变量，并且能够使用 curl 和 apt-get 等。但是，当尝试运行诸如 gem install bundler 之类的命令时，我收到代理错误。为了让 Ruby 像所有其他工具一样尊重代理，我需要做一些不同的事情吗？

$ gem install --debug -V bundler

Answer 1

只是更精确一些。
您的 407 Proxy Authentication Required 错误意味着您必须为您的代理使用登录名和密码。

您可以使用 --http-proxy 选项添加它，模式如下:

gem install --http-proxy http://login:password@proxyServer:proxyPort yourGem

但是，如果您的密码包含一些特殊字符，这将不起作用。
实际上，由于选项值必须与 URL 匹配，一些字符是被禁止的。

如果您不确定，您可以在执行命令之前在 shell 中执行以下操作，而不是在 gem install 命令中指定代理:

set HTTP_PROXY=http://proxyServer:proxyPort
set HTTP_PROXY_USER=login
set HTTP_PROXY_PASS=password
set HTTPS_PROXY=http://proxyServer:proxyPort
set HTTPS_PROXY_USER=login
set HTTPS_PROXY_PASS=password
