ruby-on-rails - 安装 ruby gem

Question

当我运行

这样的 Ruby 命令时

gem install heroku

或

gem update --system

我收到警告

ERROR:  Could not find a valid gem 'heroku' (>= 0) in any repository
ERROR:  While executing gem ... (Gem::RemoteFetcher::FetchError)
Errno::ECONNREFUSED: No connection could be made because the target machine
actively refused it. - connect(2) (http://rubygems.org/latest_specs.4.8.gz)

我浏览了几篇相关的帖子，其中大部分都提到了网络问题；我关闭了所有防病毒/防火墙软件，但没有成功。请注意，同一网络上的其他人不会面临这些问题。我对如何继续感到困惑。

旧帖子，但这可能对其他人有帮助。指定您的代理。即使已经设置了 http_proxy 环境变量，这似乎也有效:

gem install heroku --http-proxy http://yourproxyserver:port
