How to install guard-test with docker?

I am using rails, docker.

In my old application, there are some old methods and gems.

In my Gemfile, I added group :development, :test do gem 'guard-test', github: 'guard/guard-test' end

Then run docker-compose build and docker-compose up, the error message is:

What's meaning about that?

You need to run bundle install in your Docker container.
