Installing Ruby 2.5.0

I just installed Ruby 2.5.0, which was released this past Christmas (Dec 25 2017). All in all, it took about 13 minutes with no bumps in the road. Pretty great!

I only need it for the work repo, but I'm happy to have it, too. I also wasn't too sure how to go about it, and said, "Well here goes."

git pull upstream master
# pulled from repo with new Ruby version set
rbenv install 2.5.0
#=> ruby-build: definition not found: 2.5.0
# The following versions contain `2.5.0' in the name:
#  2.5.0-dev
#  rbx-2.5.0
# 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 && brew upgrade ruby-build
#=> completed with no errors
rbenv install 2.5.0
#=> Installed ruby-2.5.0
rbenv global 2.5.0
# set Ruby version for the whole machine
ruby -v
#=> ruby 2.5.0p0 (2017-12-25 revision 61468) [x86_64-darwin16]
bundle install
#=> rbenv: bundle install: command not found

# The `bundle install' command exists in these Ruby versions:
#  2.3.4
gem install bundler
# 1 gem installed
# install all gems to new Ruby version needed for repo

And that was it! Well, just for good measure, I migrated:

bin/rails db:migrate

Hope it's as easy for you!

Thank you. Your post help me to resolve a problem in ruby on rails course


By the way, I have another problems when trying to install older version of ruby. It turn out that older versions below 2.4.x need legacy openssl version 1.0.x.

I am running at opensuse tumbleweed which most packages need openssl 1.1.x. I have tried to do bleeding edge by put libopenssl-1.0.x.so directly in /usr/lib, but rbenv keeps complaining when i want to install ruby 2.2.x.

Can you help me resolve this problem?

Ah sorry, just seeing this now... Guessing you don't need help anymore right?
