ruby-on-rails - 频繁出现 Gem RemoteFetcher::FetchError。任何解决方法？

Question

最近几天我每天都经常收到这个错误...

$ gem install rails -v 3.2.1
ERROR:  While executing gem ... (Gem::RemoteFetcher::FetchError)
    bad response Forbidden 403 (http://production.cf.rubygems.org/gems/rdoc-3.12.gem)

我的理解基于 previous question这是由于远程存储库出现问题，解决方案是稍等片刻，然后重试。事实上，有时当我等待几个小时或过夜时，安装命令会起作用。

但是，我希望获得更可靠的体验。

我想到了下载rails-3.2.1.gem等文件然后运行...

$ gem install --local ~/Desktop/rails-3.2.1.gem

但这给了我...

$ gem install --local ~/Desktop/rails-3.2.1.gem 
ERROR:  While executing gem ... (Gem::DependencyError)
    Unable to resolve dependencies: rails requires railties (= 3.2.1)

我可以尝试下载 railties。也许我会。但我感觉自己掉进了一个兔子洞，整天都在寻找一个又一个依赖。

安装 gems 的任何替代有效方法？我可以通过我的存储库规范做些什么来让 gem 安装更可靠吗？

确保您的 rvm ssl 证书是最新的。

检查他们的状态

$ rvm osx-ssl-certs status all

更新它们!

$ rvm osx-ssl-certs update all
