The command "bundle install" is used in Ruby on Rails applications to install all the gems (libraries or plugins) specified in the Gemfile.
When you start a new Ruby on Rails project, you usually define the required gems in a file called "Gemfile". Each gem has a specified version or a range of compatible versions.
The "bundle install" command reads the Gemfile and downloads and installs the exact versions of the gems specified. It checks for dependencies among the gems and also ensures that all required gems are downloaded and installed correctly.
By running "bundle install", you make sure that all the necessary gems are installed and ready for use in your Rails application. It fetches the gems from the default RubyGems repository or other specified sources and installs them in your project's directory.
Once the bundler completes the installation, the gems are available for your application to use, allowing you to include them in your code and take advantage of their functionality.
