So you have finally decided to dive into the Ruby world and create your own awesome projects! Congratulations 🎉. But wait, you've encountered an issue - you need to install a specific version of a Ruby gem. Don't worry, I've got your back! In this blog post, I'll guide you through the process of installing a specific version of a Ruby gem with ease.

The Problem: Installing a Specific Version of a Ruby Gem ❔

Imagine this scenario: you are using a gem in your project, and suddenly, you come across bugs or compatibility issues. You might have received a suggestion from a helpful developer to use a specific version of that gem, but you're unsure how to go about it. Well, worry no more! I'll walk you through the solution step by step.

Solution 1: Specify the Version in Gemfile 📝

The first solution is to add the specific version of the gem to your project's Gemfile. The Gemfile is a powerful tool using which you can manage your project's dependencies. Let's walk through the process:

1. Open your project's Gemfile in your favorite text editor.

2. Locate the line where you define the gem you want to install. It will look something like this:

   gem 'gem-name'

3. To install a specific version of the gem, modify the line as follows:

   gem 'gem-name', '1.2.3'

   Replace '1.2.3' with the actual version you want to install.

4. Save the Gemfile and exit.

5. Run the following command to install the gem using the specified version:

   bundle install

And voila! You have successfully installed a specific version of the gem using your project's Gemfile.

Solution 2: Installing Directly from the Command Line ⌨️

If you prefer to install the specific gem version directly from the command line, you can use the handy gem tool. Follow these steps:

1. Open your terminal or command prompt.

2. Execute the following command, replacing gem-name with the name of the gem you want to install and 1.2.3 with the specific version:

   gem install gem-name -v 1.2.3

   For example, to install version 1.2.3 of the rails gem, the command would be:

   gem install rails -v 1.2.3

3. Hit enter and let the magic happen ✨

You're all set! You've successfully installed the specific version of the gem using the gem tool without any hassle.
