Below is the spec file I'm trying to execute using rspec
My setup
ruby 2.7.4p191
Rails 6.1.4
By the way I'm not having any problem running my spec using $ bundle exec rspec. I'm just curious how can I test my specs using the command $ rspec which most likely I will be using all throughout my career as a rails developer.

Answer 1

If you are working with bundler, most of the time you'll want to run gems under de bundled context; for rspec that is always true. You should either be using bundle exec (which you can alias to something shorter), or use the binstub with bin/rspec.
If you add ./bin to your PATH environment variable, you can run binstubs without needing to prefix with bin/; so you could do just rspec to call the binstub.

Answer 2

Prepending bundle exec tells the bundler to execute this command in context of the current bundle.
Try doing the following steps:-
gem install rubygems-bundler
gem regenerate_binstubs
Then try using rspec without bundle exec
