pod install するとエラーが起きる時の対応

最終更新日:

環境

  • macOS Big Sur
  • zsh

pod install できない

下記エラーが出た。
macOS をアップデートする度に出る気がする。

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

$ pod --version
zsh: /usr/local/bin/pod: bad interpreter: /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/bin/ruby: no such file or directory

$ pod
zsh: /usr/local/bin/pod: bad interpreter: /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/bin/ruby: no such file or directory

解決方法

最後エラーがでるけど無視する。

$ sudo gem update --system -n /usr/local/bin
