1 、执行pod update 报错如下
[!] /bin/bash -c
set -e
sh build.sh cocoapods-setup
./scripts/swift-version.sh: line 59: [: =: unary operator expected
No version of Xcode found that supports Swift 2.2
2、检查pod 版本 和ruby 版本
✗ pod --version
1.2.1.beta.1
✗ ruby --version
ruby 2.0.0p648 (2015-12-16 revision 53162) [universal.x86_64-darwin15]
3 、升级ruby
先参考ruby升级链接ruby升级链接
安装ruby版本管理器rvm
#1、 RVM安装
$ curl -L get.rvm.io | bash -s stable
# 2、 之后就是等待一段时间之后，就可以安装成功了，使用以下命令来验证
$ source ~/.bashrc
$ source ~/.bash_profile
# 3、 测试是否安装正常
$ rvm -v
#1、查看当前ruby版本
$ ruby -v
这一步会显示出来当前ruby的版本
#2、列出已知ruby的版本
$ rvm list known
稍等一下，会出现很多平台不同的ruby的版本，我因为是需要2.2.2以上的版本，所以直接安装2.2.4版本
#3、安装ruby 2.2.4
$ rvm install 2.2.4
解释安装总是没有一帆风顺的
1、$ rvm install 2.2.4 会出现报错
✗ rvm install 2.2.4

2、根据提示需要更新brew
✗ brew update
Error: /usr/local must be writable!
更新brew依然报错
可参考链接：http://securityer.lofter.com/post/1d0f3ee7_bcf5f05
大致过程是 执行✗ brew doctor 命令 会显示如下
Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry and just ignore them. Thanks!
Warning: /usr/local is not writable.
You should probably change the ownership and permissions of /usr/local
back to your user account.
sudo chown -R $(whoami) /usr/local
Warning: /usr/local is not writable.
Even if this directory was writable when you installed Homebrew, other
software may change permissions on this directory. For example, upgrading
to OS X El Capitan has been known to do this. Some versions of the
"InstantOn" component of Airfoil or running Cocktail cleanup/optimizations
are known to do this as well.
You should probably change the ownership and permissions of /usr/local
back to your user account.
sudo chown -R $(whoami) /usr/local
Warning: Your Homebrew is outdated.
You haven't updated for at least 24 hours. This is a long time in brewland!
To update Homebrew, run `brew update`.
接着
✗ sudo chown -R $(whoami) /usr/local
Password:

依然报错 再执行一遍brew update
✗ brew update
执行结果类似如下
