今天把mac升级了一下系统，升级到了10.15.1，结果pod报错
-bash: /usr/local/bin/pod: /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/bin/ruby: bad interpreter: No such file or directory
在网上找的解决办法：
1、更新gem：
sudo gem update --system
2、查看gem源
gem sources -l
如果显示的不是https://gems.ruby-china.com/，则需要更改源
gem sources -a https://gems.ruby-china.org
- 升级cocoapods：
sudo gem install -n /usr/local/bin cocoapods --pre
- 查看升级后的cocoapods版本：
pod --version
这时候我的终端还是显示报错

需要去git官网重新下载git
https://git-scm.com/download/mac
重新下载安装完成后就可以了。
