sudo gem install cocoapods
ERROR: Could not find a valid gem ‘cocoapods’ (>= 0), here is why:
Unable to download data from https://rubygems.org/ – Errno::ECONNRESET: Connection reset by peer – SSL_connect (https://rubygems.org/latest_specs.4.8.gz)
上面这个错误可能是由于GFW引起了， 所以把source rubygems.org改成baobao.com就可以了
$ gem sources --remove https://rubygems.org/ $ gem sources -a https://ruby.taobao.org/ $ gem sources -l *** CURRENT SOURCES *** https://ruby.taobao.org
