zsh: command not found: bundle (after gem install bundle)

Question

Why zsh: command not found: bundle after gem install bundler?

I tried setting path=( /usr/local/lib/ruby/gems/2.2/gems/ ~/bin /bin /sbin /usr/bin /usr/sbin /usr/local/bin /usr/local/sbin ) in /etc/zshrc and source /etc/zshrc to no avail.

I had the same issue using zsh and this fixed it:

$ echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.zshenv
$ echo 'eval "$(rbenv init -)"' >> ~/.zshenv
$ echo 'source $HOME/.zshenv' >> ~/.zshrc
$ exec $SHELL
