"Uninitialized constant RSpec::Support"

[adamdullenty]

Hi,

We are having trouble using rspec_tap in a project.

It works fine in development but as soon as RAILS_ENV is set to test we get the following errors, e.g. when running rake tasks:

RAILS_ENV=test ./bin/rake db:drop
The Gemfile's dependencies are satisfied
rake aborted!
Bundler::GemRequireError: There was an error while trying to load the gem 'rspec_tap'.
Gem Load Error is: uninitialized constant RSpec::Support

My first thought was that the issue might be down to this line in the gemspec: https://github.com/appleton/rspec_tap/blob/master/rspec_tap.gemspec#L21 - is it requiring rspec under development environment but not under any others?

This also raises another question: should rspec_tap / rspec be loaded when we're not running specs?

I just ran into this. Adding require: false in the Gemfile fixed it.

@adamdullenty is rspec itself not in your Gemfile for the test environment?
