Invalid gemspec error in ZenTest. Invalid requirements

Question

After installing some testing tools, I keep getting an Invalid gemspec error anytime I type a command. The following error:

Invalid gemspec in [/var/lib/gems/1.9.1/specifications/ZenTest-4.10.1.gemspec]: Illformed requirement ["< 3.0, >= 1.8"]

I have tried updating to the latest ZenTest gemfile of 4.11.0 and downgrading to earlier versions with no luck. I have tried uninstalling them gemfiles and re-installing them using the following procedure:

$ gem uninstall ZenTest

$ sudo gem update --system

$ gem install ZenTest

The warning still comes up.

Why is ["< 3.0, >= 1.8"] an Illformed requirement? When I have updated to the latest gem files for my program? What am I doing wrong?

Answer 1

According to this thread on Github, it suggests changing the gemspec line from:

["< X.X,>= X.X"] to ["< X.X",">= X.X"]

I tested it and it has worked so far. It makes sense to me that maybe it's a syntax error. But again, I am learning and am not an expert nor do I have a full grasp on terminology yet. I don't take credit for this fix as it was the gentleman in the thread I found on GitHub. Just wanted to share.
