频繁出现Gem RemoteFetcher :: FetchError.任何解决方法？

Question

过去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)

我之前基于前一个问题的理解是,这是由于远程存储库存在问题而解决方案是等待一段时间再试一次.实际上,有时当我等待几个小时或一夜之间安装命令有效.

但是,我希望获得更可靠的体验.

我想过下载等文件rails-3.2.1.gem,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了一整天的依赖之后寻找依赖.

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？

Answer 1

确保您的rvmssl证书是最新的.

检查他们的状态

$ rvm osx-ssl-certs status all

更新他们!

$ rvm osx-ssl-certs update all

Answer 2

你必须添加" http://rubygems.org ",

但在此之前删除https源,因为它将卡在证书错误并添加http.

所以步骤将是:

1. gem sources - 检查来源
2. gem sources -a http://rubygems.org/ - 将添加http源
3. gem sources --remove https://rubygems.org/ - 将删除https源

Answer 3

有没有在你的来源中使用RubyGems的原因？如果没有,请添加

gem sources -a http://rubygems.org

然后再试一次.

Answer 4

我最后做的是将 rdoc 3.12 gem 下载到我的桌​​面（基于原始错误），然后安装它......

$ gem install --local ~/Desktop/rdoc-3.12.gem

然后我$ gem install rails又跑了，终于成功了。
