How To Upgrade Rubygems – Ruby

To upgrade RubyGems (the package manager for Ruby) to the latest version, follow these steps:

1. Check Your Current Version of RubyGems

You can check the current version of RubyGems installed on your system by running the following command:

gem -v

2. Upgrade RubyGems

To upgrade RubyGems, you can use the following command:

sudo gem update --system

• This command will update RubyGems to the latest version available.
• sudo is used to ensure that the command has the necessary permissions to update the RubyGems system-wide (this is particularly important on Unix-like systems such as Linux and macOS).

3. Verify the Upgrade

After upgrading, you can verify that RubyGems has been updated by running:

gem -v

This should now show the updated version of RubyGems.

Optional: Update Ruby (if necessary)

If you need to update Ruby itself, which may be required if you’re running an older version of Ruby that isn’t compatible with the latest version of RubyGems, follow these steps:

On macOS using Homebrew:

brew update
brew upgrade ruby

On Ubuntu/Debian:

sudo apt-get update
sudo apt-get install ruby-full

Once Ruby is updated, RubyGems should work seamlessly with the new version of Ruby.

Summary of Steps:

1. Check RubyGems version: gem -v.
2. Upgrade RubyGems: sudo gem update --system.
3. Verify the upgrade: gem -v.
4. (Optional) Update Ruby if needed.
