First of all apologies for a rails-ish post but i think this is a more general ruby gems problem. I'm trying to freeze the rubyzip gem into an app with rake, and get an error that it isn't installed. But it is installed: > gem list | grep zip rubyzip (0.9.1) I have this line in my config: config.gem "rubyzip", :version => '0.9.1' And now i try to do rake gems:install It bombs out with a big stack trace, which is included at the bottom of this post for reference, with final part being: Missing these required gems: rubyzip = 0.9.1 You're running: ruby 1.8.6.111 at /usr/bin/ruby1.8 rubygems 1.3.5 at /home/max/.gem/ruby/1.8, /var/lib/gems/1.8 Run `rake gems:install` to install the missing gems. Which is telling me to do what i just tried to do. Any ideas anyone? I have the exact same problem with the memcache-client gem as well. grateful for any advice - max -- Posted via http://www.ruby-forum.com/.
