ruby-on-rails – 频繁出现Gem RemoteFetcher :: FetchError.有

$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)

我基于previous question的理解是,这是由于远程存储库的问题,解决方案是等待一会儿再试一次.实际上,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.

我想到下载rails-3.2.1.gem等文件,然后运行……

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

但那给了我……

$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)

我可以尝试下载铁路.也许我会.但是我感觉到一个兔子洞陷入困境,在整天依赖之后寻找依赖.

任何其他有效的安装宝石的方法？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？
