How can I update Ruby version 2.0.0 to the latest version in Mac OS X v10.10 (Yosemite)?

Question

I need to update my Ruby version from 2.0.0 to the latest version. I can not use some gems because my version is not updated. I had used Homebrew to install Ruby some time ago. How can I update my Ruby version?

what happens when you type `which rvm` or `which rbenv` in your command line — MageeWorld, Jul 05 '16 at 01:36

Open your terminal and run

curl -sSL https://raw.githubusercontent.com/rvm/rvm/master/binscripts/rvm-installer | bash -s stable

For the rvm command to work, you need to run:

source ~/.rvm/scripts/rvm

Now, run rvm list known

This shows the list of versions of the Ruby interpreter.

Now, run rvm install ruby@latest to get the latest Ruby version.

If you type ruby -v in the terminal, you should see ruby X.X.X.

If it still shows you ruby 2.0., run rvm use ruby-X.X.X --default.

Prerequisites for Windows 10:

C compiler. You can use http://www.mingw.org/
make command available otherwise it will complain that "bash: make: command not found". You can install it by running mingw-get install msys-make
Add "C:\MinGW\msys\1.0\bin" and "C:\MinGW\bin" to your path environment variable

This isn't quite a good solution, because if you want to upgrade ruby version in future, you should do that through rvm. Clearer solution is to install and lead ruby latest version through the brew. Managing 1 tool is easier than 2. Answer below can help on that. – hamsternik Nov 02 '17 at 15:28

I had to add ` --auto-dotfiles` as suggested by the instructions, and run with `sudo`. – Ibrahim.H Oct 07 '22 at 18:12
After the installation you don't need to restart Terminal to start using `rvm`. You should only need to execute the indicated `source` command, which should work with: `source ~/.rvm/scripts/rvm`. – Ricardo Barroso Nov 21 '22 at 19:31

Brew only solution

A better solution

From the comments (kudos to Maksim Luzik), I haven't tested but seems like a more elegant solution:

After installing Ruby through brew, run the following command to update the links to the latest Ruby installation: brew link --overwrite ruby

A solution

Using brew is enough. It's not necessary to install rvm and for me it just complicated things.

By brew install ruby you're actually installing the latest (currently v2.4.0). However, your path finds 2.0.0 first. To avoid this just change precedence (source). I did this by changing ~/.profile and setting:

export PATH=/usr/local/bin:$PATH

After this, I found that the bundler gem was still using version 2.0.0. Just install it again: gem install bundler

I recommend rbenv* https://github.com/rbenv/rbenv

* If this meets your criteria: https://github.com/rbenv/rbenv/wiki/Why-rbenv?:

rbenv does…

Provide support for specifying application-specific Ruby versions.

Let you change the global Ruby version on a per-user basis.

Allow you to override the Ruby version with an environment variable.

In contrast with RVM, rbenv does not…

Need to be loaded into your shell. Instead, rbenv's shim approach works by adding a directory to your $PATH.

Override shell commands like cd or require prompt hacks. That's dangerous and error-prone.

Have a configuration file. There's nothing to configure except which version of Ruby you want to use.

Install Ruby. You can build and install Ruby yourself, or use ruby-build to automate the process.

Manage gemsets. Bundler is a better way to manage application dependencies. If you have projects that are not yet using Bundler you can install the rbenv-gemset plugin.

Require changes to Ruby libraries for compatibility. The simplicity of rbenv means as long as it's in your $PATH, nothing else needs to know about it.

INSTALLATION

Install Homebrew http://brew.sh

Then:

$ brew update
$ brew install rbenv ruby-build

# Add rbenv to bash so that it loads every time you open a terminal
echo 'if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi' >> ~/.bash_profile
source ~/.bash_profile

$ rbenv install --list
Available versions:
 1.8.5-p113
 1.8.5-p114
 […]
 2.3.1
 2.4.0-dev
 jruby-1.5.6
 […]
$ rbenv install 2.3.1
[…]

Set the global version:

$ rbenv global 2.3.1
$ ruby -v
ruby 2.3.1p112 (2016-04-26 revision 54768) [x86_64-darwin15]

If you are not showing the updated version then

$ rbenv rehash

Set the local version of your repository by adding .ruby-version to your repository's root directory:

$ cd ~/whatevs/projects/new_repo
$ echo "2.3.1" > .ruby-version

For OS X, visit this link.

@ChuchaC No prob. But before you do, this is from the rbenv readme: _"Compatibility note: rbenv is incompatible with RVM. Please make sure to fully uninstall RVM and remove any references to it from your shell initialization files before installing rbenv." — https://github.com/rbenv/rbenv#installation_ — SoAwesomeMan, Jul 06 '16 at 02:33
didn't helped. Still getting standard 2.0.0 version for `ruby -v` after `rbenv global ...` — tuxSlayer, Sep 08 '16 at 10:57
There's one additional step after `brew install rbenv` Run `rbenv init` and add one line to .bash_profile as it states. After that reopen your terminal window, do `rbenv install 2.3.1`, `rbenv global 2.3.1` and rbenv will do its work — SGI, Sep 30 '16 at 12:01
Probably late but for future references for people who encountered the same issue as @tuxSlayer , `rbenv rehash` after `rbenv global` worked for me — Sean, Feb 01 '17 at 03:01
After `rbenv init`, `ruby -v` outputs the correct version 2.1.2, but bundle runs encounters some error like this `paperclip-5.0.0.beta1 requires ruby version >= 2.1.0, which is incompatible with the current version, ruby 2.0.0p648`. Finally manage to get it work with a run of `rbenv rehash`. Thanks @Sean — James, Apr 14 '17 at 03:43

You can specify the latest version of Ruby by looking at Download Ruby.

Fetch the latest version:

curl -sSL https://get.rvm.io | bash -s stable --ruby

Install it:
```
rvm install 2.2
```
Use it as default:
```
rvm use 2.2 --default
```

Or run the latest command from ruby:

rvm install ruby --latest
rvm use 2.2 --default

Edit:

Set the $PATH environment variable. Add this at the end of your ~/.zshrc file. On Mac Intel:

if [ -d "/usr/local/opt/ruby/bin" ]; then
  export PATH=/usr/local/opt/ruby/bin:$PATH
  export PATH=`gem environment gemdir`/bin:$PATH

You can add the flag --no-document if you do not want to download the documentation. Here is sample output after running the command:
