homebrewをupgradeかけたら、gitの補完ができなくなった $ git _git:.:26: no such file or directory: /usr/local/share/zsh/site-functions/git-completion.bash (anon):6: command not found: __git_main なので、こうする $ ln -s /usr/local/etc/bash_completion.d/git-completion.bash /usr/local/share/zsh/site-functions/git-completion.bash もしも、site-functionsに_gitがある場合は消したほうがいいらしい。 ref: git completion in zsh doesn't work after #16961
