升级系统导致cocoapods无法正常使用。
运行搜索开源库
liangchengnandeMacBook-Pro:YDChartsDemo ken$ pod search ios-charts
-bash: /usr/local/bin/pod: /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/bin/ruby: bad interpreter: No such file or directory
这是什么鬼，一脸懵逼啊。
百度啊。谷歌啊，都说是要更新pods ，说干就干
liangchengnandeMacBook-Pro:YDChartsDemo ken$ sudo gem install -n /usr/local/bin/ cocoapods

一路小激动，这速度，杠杠的，眼看就要到黎明，最后这是什么鬼。继续百度，谷歌了一番，要更新 gem 那就别闲着了，时间就是就是金钱啊。。。

中间省略几万字。。。。
RubyGems installed the following executables:
/System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/bin/gem
Ruby Interactive (ri) documentation was installed. ri is kind of like man
pages for ruby libraries. You may access it like this:
ri Classname
ri Classname.class_method
ri Classname#instance_method
If you do not wish to install this documentation in the future, use the
--no-document flag, or set it as the default in your ~/.gemrc file. See
'gem help env' for details.
RubyGems system software updated
完成更新，继续之前操作，更新pods
liangchengnandeMacBook-Pro:YDChartsDemo ken$ sudo gem install -n /usr/local/bin/ cocoapods --pre
一路顺利
liangchengnandeMacBook-Pro:YDChartsDemo ken$ pod setup
省略几万字
看到熟悉的Setup completed 完成
看下可不可执行
iangchengnandeMacBook-Pro:YDChartsDemo ken$ pod search ios-charts
。。。。。
完美
