In macOS, Ruby is installed to the not recommended folder by rbenv because of oh-my-zsh plugin file. about setup

[hidehiro98]

ohmyzsh/ohmyzsh#4998 , ohmyzsh/ohmyzsh#4384 and ohmyzsh/ohmyzsh#6168 look doing same thing.
So I'll try them.

The modification above did not work well, so I stop using rbenv plugin of zsh and use rbenv with itself.
It works well.

~/.zshrc
Deleted rbenv in this line
plugins=(gitfast brew rbenv last-working-dir common-aliases sublime zsh-syntax-highlighting history-substring-search)

Added this line
eval "$(rbenv init -)"

Restart terminal

which ruby #=> /Users/hidehiro/.rbenv/shims/ruby
