ruby-build: definition not found -> Missing How To Hint

[muescha]

there shout be a hint in the commandline and the README how to update the definitions.

i got this error:

i tried this and get the defintions updated (thanks to hathaway ):

brew unlink ruby-build
brew install ruby-build

[muescha]

i dont tried it, but this way without brew looks very cryptic :-(

http://squarism.com/2012/02/27/upgrading-rbenv/

i think it would be better if rbenv install looks directly in the github repository for the current definitions without reinstalling?

I had to do the unlink/install for ruby-build too. Is this a bug?

[geraldhiller]

same here

On OS X, I use Homebrew and an alias to do updates to rbenv and ruby-build:

alias rbu='brew upgrade rbenv; brew upgrade ruby-build'

If no updates are needed you see benign error messages, for example:

Error: rbenv-0.4.0 already installed
Error: ruby-build-20130227 already installed

[robblovell]

With ruby-build installed as a plugin to rbenv, the homebrew re-install doesn't load new definitions so that rbenv can find them. To get new definitions I had to delete ~/.rbenv/plugins then follow the instructions to install ruby-build as a plugin for rbenv:

rm -rf ~/.rbenv/plugins/ruby-build
git clone git://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-build

This is a great time waster. By the time I am getting around to installing another ruby, a few months have passed and I have forgotten the location and git incantation for updating the definitions (remembering to do brew uninstall brew install of ruby-build is not a better way).

Both rbenv and ruby-build need to coordinate a better way to update definitions, all of them, where ever they are located.

rbenv update definitions
rbenv which ruby-build
ruby-build update definitions

That would save everyone a lot of google time.

[jwfearn]

A useful techniques is to use brew upgrade ruby-build (note: _upgrade_ not
update.) I use utility functions for keeping up-to-date with brew, rbenv,
and ruby-build:
#.bashrc
function bud { brew update; brew doctor; }
function rbu { brew upgrade rbenv; brew upgrade ruby-build; }
function rbis { ruby-build --definitions; }
function rbs { rbenv -v; ruby-build --version; rbenv versions; ruby -v; }

Most days I'll run:

$ bud

Then I'll fix reported issues, if any. Then:

$ rbu

If I see that ruby-build was updated, then I'll run:

$ rbis

and eyeball it to see what changed. If I see a new definition that I want,
I'll install it.

Hope this helps.

This solution worked perfectly for me:

If people used a package manager to install ruby-build, they should upgrade using the same package manager. If they cloned it via git, they need to do a git pull. We might have better instructions for this in the future, but for now, this is what we've stuck with. There are upgrade instructions in the official wiki.
