问题
When I try to install ZenTest:
gem install ZenTest
I get the following error:
Invalid gemspec in [C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/specifications/ZenTest-4.8.4.gemspec]: Illformed requirement ["< 2.1, >= 1.8"]
I tried cleaning up the gems and removing the ZenTest to no avail.
What's wrong?
回答1:
I've just spoken with Ryan Davis, the author of ZenTest. He tells me that this is due to a bug in RubyGems and they're preparing a release that fixes it.
In the meantime, downgrade to 4.8.3.
回答2:
Updating rubygems to 1.8.25 seems to fix the problem (https://github.com/seattlerb/zentest/issues/28)
回答3:
to cleanup the gem, move the gemspec file to some other location.
e.g: in ubuntu to cleanup the gem, do
sudo mv /var/lib/gems/1.8/specifications/ZenTest-4.8.4.gemspec /var/tmp/
