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

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?

This works for me.

sudo gem update --system

If above command give error of ruby version then follow below steps.

Note I have choose ruby 3.3.6 version from list

 brew install rbenv  
 rbenv init  
 rbenv install --list 
 rbenv install 3.2.6 
 ruby -v

If not showing version please close terminal and open again and hit ruby -v - if still not showing then hit below global command

rbenv global 3.2.6
rbenv rehash

If not showing version please close terminal and open again and hit

ruby -v

Then you can install particular cocoa pod version

sudo gem install cocoapods -v 1.15.2

Homebrew-only solution

A better solution

From the comments (kudos to Maksim Luzik), what 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 --force

Reopen a terminal to reset zshrc. Check the installlation with ruby --version and gem --version, then run gem install bundler.

Earlier 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

✅ Working 2023 method:

Upgrade using Homebrew:

brew upgrade ruby
echo 'export PATH="/opt/homebrew/opt/ruby/bin:$PATH"' >> ~/.zshrc
brew link --overwrite ruby

Then restart the Terminal (make sure you terminate all instances, quit and open again)

Then ruby -v to check if it linked correctly.

💡Recommended Followup:

It's not required, but you can run the following after upgrading Ruby to update gem files:

gem update --system 3.4.2

⚠️ The above version may be changed when you have upgraded your Ruby installation. Please use the correct version as reported after the installation of Ruby.

You can use the steps mentioned in How to install Ruby in a macOS for local development.

It worked great for me on macOS v13.3.1 (Ventura) (a) (22E772610a).

I ended up using the steps below due to React Native 0.70 and macOS v12 (Monterey).

brew install ruby

Edit .zshrc:

open -e ~/.zshrc

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
  eval "$(rbenv init -)"
fi

Apple silicon

if [ -d "/opt/homebrew/opt/ruby/bin" ]; then
      export PATH=/opt/homebrew/opt/ruby/bin:$PATH
      export PATH=`gem environment gemdir`/bin:$PATH
      eval "$(rbenv init -)"
    fi

Don't want Homebrew to update your version? Then:

brew pin ruby

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

Output:

Available versions:
 1.8.5-p113
 1.8.5-p114
 […]
 2.3.1
 2.4.0-dev
 jruby-1.5.6
 […]

And:

rbenv install 2.3.1

Set the global version:

rbenv global 2.3.1
ruby -v

Output:

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

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

The simplest way is definitely to enter the following command in the terminal:

sudo gem update --system

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

sudo gem update --system
Password:
Updating rubygems-update
Fetching: rubygems-update-2.6.8.gem (100%)
Successfully installed rubygems-update-2.6.8
Parsing documentation for rubygems-update-2.6.8
Installing ri documentation for rubygems-update-2.6.8
Installing darkfish documentation for rubygems-update-2.6.8
Installing RubyGems 2.6.8
RubyGems 2.6.8 installed
Parsing documentation for rubygems-2.6.8
Installing ri documentation for rubygems-2.6.8

------------------------------------------------------------------------------

RubyGems installed the following executables:
    /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/bin/gem

Ruby Interactive (ri) documentation was installed. ri is kind of like man
pages for ruby libraries. You may access it like this:
  ri Classname
  ri Classname.class_method
  ri Classname#instance_method

Use:

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

Install Ruby

rbenv install 2.6.5

rbenv global 2.6.5

ruby -v

In case of the error “Requirements installation failed with status: 1.”, here's what to do:

Install Homebrew (for some reason it might not work automatically) with this command:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Then proceed to install rvm again using

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

Quit, reopen Terminal, and then:

rvm install 2.2
rvm use 2.2 --default

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

  1. Fetch the latest version:

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

  2. Install it:

    rvm install 2.2

  3. 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
