-standalone : Creates a bundle that can work without depending on Bundler at runtime.

-path : The specific locations where gems are going to be installed.

-frozen: Gemfile.lock will not be updated after this install.

-force: Downloads every gem, even if the required versions are already available.

Activating deployment mode on development machines will cause an error when the Gemfile is modified.

-deployment: Runs bundle in the production environment.

We will cover the most commonly used ones. There are multiple options you can use to change the way bundle install works. This ensures that other developers on your Ruby application run the same third-party code on every machine. Once the installation is finished run bundle install, this will create Gemfile.lock in your repository.
