Before you install Rails, you should check to make sure that your system has the proper prerequisites installed. These include:

• Ruby 3.2.0+
• SQLite3 (Optional)
• Rails

Rails requires Ruby version 2.7.0 or later. It is preferred to use the latest Ruby version. If the version number returned is less than that number (such as 2.3.7, or 1.8.7), you'll need to install a fresh copy of Ruby.

Assets compile require the build tools. These libraries are required as below:

• Node.js 16.15.0+
• Yarn 1.12.18+

1. Get the latest version of Ruby at https://www.ruby-lang.org/en/downloads/. They have several tools on each major platform to install Ruby:
   • On Linux/UNIX, you can use the package management system of your distribution or third-party tools (rbenv and RVM).
   • On macOS machines, you can use third-party tools (rbenv and RVM).
   • On Windows machines, you can use RubyInstaller.
   See the Installation page for details on using package management systems or third-party tools.
2. Download the executable installer and run it.
3. Open up a command line prompt. On macOS open Terminal.app; on Windows choose "Run" from your Start menu and type cmd. Verify that you have a current version of Ruby installed:
   copy

   ruby --version

   Rails requires Ruby version 2.7.0 or later. It is preferred to use the latest Ruby version. If the version number returned is less than that number (such as 2.3.7, or 1.8.7), you'll need to install a fresh copy of Ruby.

1. To install Rails, use the gem install command provided by RubyGems:
   copy

   gem install rails

2. To verify that you have everything installed correctly, you should be able to run the following in a new terminal:
   copy

   rails --version

   If it says something like "Rails 7.0.0", you are ready to continue.

1. Start a command prompt window or terminal and change directory to starterkit/_keenthemes/tools
   copy

   cd starterkit/_keenthemes/tools

2. Install dependencies with either one, yarn or npm:
   copy

   yarn install

   You can use either one.
   copy

   npm install

   This command will fetch all dependencies listed in starterkit/_keenthemes/tools/package.json and place them into _keenthemes/tools/node_modules folder.
3. You can use Gulp  or Webpack  commands to bundle theme assets. The below command will compile all the assets(sass, js, media) to starterkit/assets folder:
   For gulp use command:
   copy

   gulp

   For webpack use command:
   copy

   npm run build

   Note on the package.json file. This step is very important for Webpack in Metronic template. The default package.json works for Gulp. To make it work for Webpack, you have to modify tools/package.json and remove "type": "module". Otherwise, it will cause compilation error when running the build command.
