This is a dupe of #29

% gem update --system
% gem uninstall ZenTest
% gem install ZenTest

Thanks!

Had the same with 4.9.0 - got fixed by this:

% gem update --system
% gem uninstall ZenTest
% gem install ZenTest

as reported by zenspider

For whatever reason, I couldn't uninstall ZenTest (maybe because I upgraded RubyGems first?) without getting the same error message about an illformed requirement. The solution was to manually edit the gemspec, and then (mostly to verify that RubyGems is working properly) uninstall and reinstall:

% vim $GEM_HOME/specifications/ZenTest-4.9.0.gemspec  # assumes you're using RVM
    # add ", " to line 7
% gem uninstall ZenTest --force
% gem install ZenTest

Same problem here with my Homebrew ruby, I fixed it by editing:

/usr/local/lib/ruby/gems/2.0.0/specifications/ZenTest-4.9.5.gemspec

and changing the string on line 7:

"<3, >=1.8"

to

">=1.8"

@charlesreid1 as stated multiple times, this is not the proper solution

[charlesreid1]

If your solution is to run

% gem update --system
% gem uninstall ZenTest
% gem install ZenTest

then your solution did not work. The error message is thrown by gem, it's always thrown by gem, no matter what command you run. Only way to fix it is using a non-gem command.

If you are using Ruby 1.9 kindly navigate to folder /var/lib/gems/1.9.1/specifications using command line with root login. then issue command gedit ZenTest-4.10.0.gemspec. Edit the line written as s.required_rubygems_version = Gem::Requirement.new("<3.0, >= 1.8") to s.required_rubygems_version = Gem::Requirement.new(">= 1.8") save it. then again issue command sudo gem install GenTest. it will install by displaying message as

"Invalid gemspec in [/var/lib/gems/1.9.1/specifications/ZenTest-4.10.0.gemspec]: Illformed requirement ["< 3.0, >= 1.8"] Successfully installed ZenTest-4.10.0 1 gem installed Invalid gemspec in [/var/lib/gems/1.9.1/specifications/ZenTest-4.10.0.gemspec]: Illformed requirement ["< 3.0, >= 1.8"] Installing ri documentation for ZenTest-4.10.0... Installing RDoc documentation for ZenTest-4.10.0..."

but will install and work. you can check it in your local gem list by using "gem list" command
