Unable to install 'cocoapods' gem from rubygems.org (bad response backend read error)
提问by depthfirstdesigner
I'm getting an error when I run 'gem install cocoapods' on OSX Mavericks.
在 OSX Mavericks 上运行“gem install cocoapods”时出现错误。
$ gem install cocoapods
ERROR: Could not find a valid gem 'cocoapods' (>= 0), here is why:
Unable to download data from https://rubygems.org/ - bad response backend read error 503 (https://rubygems.global.ssl.fastly.net/quick/Marshal.4.8/cocoapods-0.27.1.gemspec.rz)
ERROR: Possible alternatives: cocoapods
Please note that I can download the cocoapods-0.27.1.gemspec.rz directly. I am running the latest version of XCode (5.0.1) and the latest version of its CLI tools. RVM is also configured to run the latest Ruby version (2.0.0p247)
请注意，我可以直接下载 cocoapods-0.27.1.gemspec.rz。我正在运行最新版本的 XCode (5.0.1) 及其 CLI 工具的最新版本。RVM 还配置为运行最新的 Ruby 版本 (2.0.0p247)

Though I'm not sure what caused read error 503I was able to work around the problem fairly easily by manually installing the cocoapods.gem.
虽然我不确定是什么原因导致 read error 503我能够通过手动安装 cocoapods.gem 很容易地解决这个问题。
If anyone else experiences similar problems (with cocoapods or any other gem), download the appropriate gem file (cocoapods-0.27.1.gem in my case) directly from RubyGems.org. Then run the gem install cocoapods-0.27.1.gem. The install command will scan the working directory first, thus detecting and installing the local gem package, cutting out the broken repository.
如果其他人遇到类似问题（使用 cocoapods 或任何其他 gem），请直接从 RubyGems.org 下载适当的 gem 文件（在我的例子中为 cocoapods-0.27.1.gem）。然后运行gem install cocoapods-0.27.1.gem. install 命令会首先扫描工作目录，从而检测并安装本地 gem 包，切出损坏的存储库。

Sometimes ,the default source for gem, https://rubygems.org/, can't be accessed.

And then new source should be added:

I found that just removing and re-adding rubygems seemed to work for me ( using the High Sierra on Mac) I prefer to use the official Rubygems repos
我发现只是删除和重新添加 rubygems 似乎对我有用（在 Mac 上使用 High Sierra）我更喜欢使用官方的 Rubygems 存储库
gem sources -r https://rubygems.org/
gem sources -a https://rubygems.org/
gem sources -u
sudo gem install cocoapods
I assume it must have been a glitch..
我想这一定是一个小故障..
