To download and install Ruby gems into a Gemfile, you can use the "bundle" command in the command line.
1. First, navigate to your project directory in the command line.
2. Next, create a new file called "Gemfile" in the root of your project directory, if it doesn't already exist.
In the Gemfile, specify the gems you want to install by adding them to the file in the following format:
3. gem 'gem-name'
Once you have specified all the gems you want to install, in the command line, run the following command:
4. bundle install
This command will download and install all the gems specified in your Gemfile.
Alternatively, if you want to add a specific version of a gem, you can use the following format in the Gemfile:
gem 'gem-name', '~> version-number'
And then run the bundle install command.
Please note that you need to have an internet connection and the bundler gem installed in your system for the above steps to work.
