rbenv install --list does not list version 2.1.2
Both rbenv and ruby-build are generally installed from Github by cloning; That's how the authors recommend we install it.
git clone https://github.com/sstephenson/rbenv.git ~/.rbenvgit clone https://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-buildIf you didn't do it that way I'd recommend that method. Then, you can simply do:
cd ~/.rbenvgit pullcd plugins/ruby-buildgit pullIf you have several plugins use:
cd pluginsfor i in *do cd $i git pull cd -doneI update every couple weeks just to pull in the latest fixes/changes.
I faced the same issue. I got the latest by running the following command:
brew upgrade --HEAD ruby-build
I had this issue on OS X 10.8.5 (so don't think OS related). I had tried updating rbenv & ruby-build via brew. 2.1.0-dev was still latest build available.
I had to force uninstall and re-install ruby-build via brew to fix the issue.
brew uninstall ruby-build --forcebrew install ruby-build
