However online a lot about MacOS Installation Cocoapods tutorial, dazzling, find a few good comprehensive look at the same time, combined with their own success examples, recorded ...

First of all, the computer is newly bought, of course, is completely not installed Cocoapods, the system is the latest MacOS 10.12.1,xcode 8.1, due to cocoapods1.1.1 's pit dad, first check their gem version and Ruby version ... Otherwise, the install will fail even if you replace the ruby source.

After Ruby-v is executed, the initial ruby version is 2.0.0,gem version 2.0.14.1

2.0 version seems to be unable to install, at least I myself in the execution of the sudo gem install cocoapods is a failure, so, first upgrade it!

The terminal performs the following code upgrade gem

sudo gem update--system

Execute the following code to upgrade Ruby to 2.2. Version 2:

The first step:
