3.2 Drag and Drop

Drag the RailsInstaller icon into the Applications folder to install.

3.3 Launch RailsInstaller

Navigate to the Applications folder and double-click the RailsInstaller to launch it.

Step 4: Setting Up Your Environment

After installing RailsInstaller, you need to configure your environment.

4.1 Open a Command Prompt/Terminal

For Windows: Press Windows + R, type cmd, and hit Enter.
For macOS: Press Command + Space, type Terminal, and hit Enter.

4.2 Verify Ruby Installation

Type the following command to check if Ruby is installed successfully:

ruby -v

You should see the Ruby version displayed on the screen.

4.3 Install Rails

Run the following command to install Rails:

gem install rails

This command installs the Rails framework. You can check the Rails installation by typing:

rails -v

Again, it should display the version of Rails that is installed.

Step 5: Creating Your First Rails Application

Now that your environment is set up, let’s create your first Rails application.

5.1 Create a New Rails Project

Use the following command to create a new Rails project:

rails new myapp

Replace myapp with your desired application name.

5.2 Navigate to Your Application Directory

Change into your application directory by typing:

cd myapp

5.3 Start the Rails Server

Start the Rails server with this command:

rails server

This will start your Rails application. Open a web browser and go to http://localhost:3000 to see your new application in action.

Step 6: Additional Configurations

6.1 Database Setup

Rails uses SQLite by default. However, if you prefer using PostgreSQL or MySQL, you’ll need to modify the Gemfile and configure database.yml. Make sure to install the necessary database server and client libraries as well.

6.2 Version Control

Consider installing Git to manage your code versions. Install Git by downloading it from git-scm.com, and after installation, verify it using:

git --version

Troubleshooting Common Issues

Path Errors: If you encounter path-related errors, ensure that Ruby and Rails are correctly installed and added to your system’s PATH variable.
Installation Failures: Check your internet connection and ensure all required components are selected during the installation process.
