rbenv on macmini

instruction

- https://github.com/rbenv/rbenv#installation

install git

- https://sourceforge.net/projects/git-osx-installer/files/

Check out rbenv into ~/.rbenv.

- $ git clone https://github.com/rbenv/rbenv.git ~/.rbenv

Optionally, try to compile dynamic bash extension to speed up rbenv. Don't worry if it fails; rbenv will still work normally:

- $ cd ~/.rbenv && src/configure && make -C src

Add ~/.rbenv/bin to your $PATH for access to the rbenv command-line utility.

$ echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bash_profile

Run ~/.rbenv/bin/rbenv init for shell-specific instructions on how to
initialize rbenv to enable shims and autocompletion.

# Load rbenv automatically by appending
# the following to ~/.bash_profile:
eval "$(rbenv init -)"

Restart shell and test

$ type rbenv
#=> "rbenv is a function"
