你能帮我完成它吗？

谁能帮我说说为什么会这样？

删除标签：这不是 Nokogiri、Mechanize 或 Selenium 问题。

标签： ruby windows-xp

【解决方案1】：

您的错误似乎是代理问题，试试下面的命令

gem install --http-proxy <your proxy host:port> <your gem name>

例如。

gem install --http-proxy http://localhost:8888 selenium-webdriver

你也可以这样做

SET HTTP_PROXY=http://%USER%:%PASSWORD%@%SERVER%:%PORT%

然后执行你的gem install

【讨论】：

+1 给你！它的工作。我在C:\Ruby193>gem install --http-proxy 3.209.30.25:80 nokogiri 下尝试并且所有下载都已开始。
