Ruby-build: Install Ruby 2.3.0

[solyarisoftware]

Hi
I'd like to install last Ruby version 2.3.0
( https://github.com/rbenv/ruby-build/releases/tag/v20151225 )

$ rbenv install --list | grep
2.3.0-dev
rbx-2.3.0

$ rbenv --version
rbenv 1.0.0-9-ga95ccd0

So I'd like to install the final 2.3.0 (and not previous 2.3.0-dev)
there is a way ?
thanks for your patience
giorgio

Could you perhaps try updating ruby-build plugin before trying again?

$ rbenv install 2.3.0
ruby-build: definition not found: 2.3.0

The following versions contain `2.3.0' in the name:
  2.3.0-dev
  rbx-2.3.0

See all available versions with `rbenv install --list'.

If the version you need is missing, try upgrading ruby-build:

  cd /Users/mislav/.rbenv/plugins/ruby-build && git pull && cd -

Thanks @mislav !
That's solved ! please close and sorry

just a note: maybe is my git-ignorance:
to update rbenv functionalities and related plugins (ruby-build)
I have to do periodically a git pull; that's correct ?

cheers

Upgrading ruby-build was not working for me.

$ rbenv install 2.3.0
ruby-build: definition not found: 2.3.0

The following versions contain `2.3.0' in the name:
  2.3.0-dev
  rbx-2.3.0

See all available versions with `rbenv install --list'.

If the version you need is missing, try upgrading ruby-build:

  brew update && brew upgrade ruby-build

$ brew update; and brew upgrade ruby-build
Already up-to-date.
Error: ruby-build HEAD already installed

Reinstalling from HEAD worked.

$ brew reinstall --HEAD ruby-build

@dideler I'm glad you solved it, but if you want to upgrade ruby-build in the future via Homebrew, you should do brew uninstall ruby-build; brew install ruby-build and not use --HEAD. This is because --HEAD installs can't be updated via brew upgrade.

@solyaris You could have closed the issue yourself as well :wink: Yes, to upgrade rbenv and ruby-build, if you installed via git clone, you'll periodically have to update via git pull, especially ruby-build which often has releases.

Thanks for the tip @mislav!

Hello, I'm having the same problem.
I already did rbenv install 2.3.0 and it was successfully installed. So i ran rbenv versions and the result are:
* system (set by /home/eduardo/.rbenv/versions/.ruby-version)
2.3.0
So, I ran rbenv local 2.3.0 and rbenv global 2.3.0 and the result, after the command versions, are:
system
* 2.3.0 (set by /home/eduardo/.rbenv/versions/.ruby-version)
But, when I ran the command ruby -v, the result are:
ruby 1.9.3p484 (2013-11-22 revision 43786) [x86_64-linux]

I want to use the latest version of ruby.

@Nigmatulin did you find a solution to this? My rbenv global 2.3.0 not working either

i had this happen to me, and what i found was the issue was at one time in the past i had installed rbenv with out brew and it was using that version vs the one that was installed by brew so you might want to do a 'which rbenv' and or --version and make sure you using the one you expected. also make sure your environment is adjusted to reflect that.

note: brew for me installed in /usr/local and brew cautions you that rbenv liked to install in ~/.rbenv which was where the old version was.

UPDATE: Debian's ruby-build is woefully out of date. Updating to the latest in github solved the issue.

I'm having trouble updating my ruby-build definitions in Debian. The output of rbenv install --list only goes as high as 2.2.0-dev. Still trying to figure out how to update this. Installed via apt-get.

@mislav ->

brew uninstall ruby-build; brew install ruby-build and not use --HEAD. This is because --HEAD installs can't be updated via brew upgrade.

^^ this was a fantastic call, I was getting the following error:

❯ brew reinstall --HEAD ruby-build

Uninstalling and reinstalling fixed it for me!
