rbenv installer & doctor scripts

rbenv-installer

The rbenv-installer script idempotently installs or updates rbenv on your system. If Homebrew is detected, installation will proceed using brew install/upgrade. Otherwise, rbenv is installed under ~/.rbenv.

Additionally, ruby-build is also installed if rbenv install is not already available.

# with curl
curl -fsSL https://github.com/rbenv/rbenv-installer/raw/master/bin/rbenv-installer | bash

# alternatively, with wget
wget -q https://github.com/rbenv/rbenv-installer/raw/master/bin/rbenv-installer -O- | bash

rbenv-doctor

After the installation, a separate rbenv-doctor script is run to verify the success of the installation and to detect common issues. You can run rbenv-doctor on your machine separately to verify the state of your install:

# with curl
curl -fsSL https://github.com/rbenv/rbenv-installer/raw/master/bin/rbenv-doctor | bash

# alternatively, with wget
wget -q https://github.com/rbenv/rbenv-installer/raw/master/bin/rbenv-doctor -O- | bash
