Specify list of gems to install

Question

npm has the package.json file to specify which node modules to install. That will be automatically be used by this command:

npm install

pip has requirements.txt to specify python modules to install. It can be used like this:

pip install -r requirements.txt

Is there a similar command for gems? Is there a way of doing:

gem install -i my-gems.json

Or something similar?

Answer 1

There is Bundler that do this.
