CocoaPods-升级到macOS Catalina报错 -b

问题描述

$ pod install
-bash: /usr/local/bin/pod: 
/System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/bin/ruby: 
bad interpreter: No such file or directory

解决方案一

重新升级安装Cocoapods。参考：https://guides.cocoapods.org/using/getting-started.html#getting-started

$ [sudo] gem install cocoapods

··· 省略 ···

$ pod install
/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/lib/ruby/2.6.0/universal-darwin19/rbconfig.rb:229: warning: Insecure world writable dir /usr/local/Cellar in PATH, mode 040777

Pod installation complete! There are 16 dependencies from the Podfile and 17 total pods installed.

解决方案二

如果是使用HomeBrew的方式安装CocoaPods，则可以按照以下顺序操作。参考：iOS-解决MacPod报错 -bash: /usr/local/bin/pod: /System/Library/Frameworks/Ruby.framework/Versions/2.0/...

1. 执行如下命令

$ brew link --overwrite cocoapods

2. 尝试Pod命令是否已经恢复，若报错则继续执行如下命令

$ brew reinstall cocoapods
 
$ brew install ruby
 
$ brew link --overwrite cocoapods

3. 尝试Pod命令是否已经恢复
