问题
I'm getting an error when I run 'gem install cocoapods' on OSX Mavericks.
$ 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)

Sometimes ,the default source for gem, https://rubygems.org/, can't be accessed.
It should be removed by command:
gem sources -r https://rubygems.org/
And then new source should be added:
gem sources -a https://ruby.taobao.org/
Update the cache:
gem sources -u
You can check sources with:
gem sources
Finally , you can install cocoapods:
sudo gem install cocoapods

It work for me:
Remove https source by command:
gem sources -r https://rubygems.org/
And then new http source should be added:
gem sources -a http://rubygems.org/
Update the cache:
gem sources -u

Though I'm not sure what caused read error 503 I was able to work around the problem fairly easily by manually installing the cocoapods.gem.
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.

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
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..
回答6:
This worked for me. Make sure to include sudo with install command.
gem sources -a http://rubygems.org/
gem sources -u
sudo gem install cocoapods

Let all http replace https,because the right cocoa pods's sources is https://ruby.taobao.org/
