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像其他工具一样尊重代理,我还需要做些什么吗？

Answer 1

只是更精确一些.
您的407 Proxy Authentication Required错误意味着您必须使用代理的登录名和密码.

您可以使用该--http-proxy选项添加它,使用以下模式:

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,则无法使用.
实际上,由于选项值必须与URL匹配,因此禁止某些字符.

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

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
