mac安装cocoapods新版本

卸载

AdministratordeMacBook-Air:~ administrator$ pod --version
1.7.5
AdministratordeMacBook-Air:~ administrator$ which pod
/usr/local/bin/pod
AdministratordeMacBook-Air:~ administrator$ sudo rm -rf /usr/local/bin/pod

安装

AdministratordeMacBook-Air:bin administrator$ sudo gem install cocoapods
Successfully installed cocoapods-1.9.3
Parsing documentation for cocoapods-1.9.3
Done installing documentation for cocoapods after 2 seconds
1 gem installed
AdministratordeMacBook-Air:bin administrator$ pod --version
-bash: pod: command not found
AdministratordeMacBook-Air:bin administrator$ 

但是，运行pod命令，并没有这个命令。

正确姿势：

AdministratordeMacBook-Air:bin administrator$ sudo gem install -n /usr/local/bin cocoapods
Successfully installed cocoapods-1.9.3
Parsing documentation for cocoapods-1.9.3
Done installing documentation for cocoapods after 2 seconds
