How do eliminate/remove a gem that is throwing errors

Question

When I run the rails console command, I'm getting the following error messages:

Invalid gemspec in [/Users/MI1/torquebox-2.0.0.beta1/jruby/lib/ruby/gems/1.8/specifications/ZenTest-4.9.0.gemspec]: Illformed requirement ["< 2.1, >= 1.8"]

When I ran gem uninstall zentest, the system said zentest was not installed.

Does anyone know how can remove this gem and annoying error message.

Answer 1

Try this to make sure you don't have multiple versions of the gem

gem cleanup

then

sudo gem uninstall zentest

Answer 2

I tried gem cleanup followed by sudo gem uninstall zentest but unfortunately that did not fix my problem.

Ultimately, I simply deleted the file and the error message was eliminated.

Thanks for the input.
