Update Ruby to Latest Version on Mac OS X
I recently needed to do a small scripting job in Ruby, and to use the gems required I needed to be on the latest version of Ruby (2.4.1). My MacBook was on an older version, so I needed to run a quick update. Here is the process I followed:
1. Check the version of Ruby installed on your Mac
Open terminal and type:
2. Install the Ruby Version Manager rvm
curl -L https://get.rvm.io | bash -s stable
Once this command has finished running you may need to restart your terminal for rvm to be recognised.
3. Install the latest version of Ruby
rvm install ruby-[version]
In my case this was
rvm install ruby-2.4.1
This took a while to run as it had to install a lot of dependencies and asked for my permission a couple of times.
4. Set the latest version of Ruby as the one you want to use
You should now be running the latest version of Ruby. You can check as before with the ruby -v command as in step 1. If you’re find that you’re not, you can set this manually. In terminal type:
rvm use ruby-2.4.1
If you want to set this latest version of Ruby as the default version, in terminal type:
rvm --default use 2.4.1
Don’t forget to replace 2.4.1 with the version number of your latest Ruby.
Hope this is helpful for someone.
