Object is not missing constant Project!

Added by hywl51 Xu over 14 years ago

I was trying to install redmine 0.9.3 with ruby 1.8.7 on a centos pc, and got the following error:

Hi, did you figure this one out? There's someone trying to use the Arch Decisions plugin and is having the same problem:
http://www.redmine.org/boards/3/topics/11664#message-14251

If you have a solution, please post it here. Otherwise, we'll keep looking and let you know.

It might be a problem with your particular combination of gems, Redmine and Ruby. Have you tried upgrading to 0.9.4?

RE: Object is not missing constant Project! - Added by Brian DeVries over 14 years ago

I just ran into a very similar error with a plugin (in this case, the redmine-checkout one). In my case, the directory that the plugin was supposed to be in was actually the top of the Subversion repository, so it had the directories `tags` and `trunk`, rather than the information that Redmine / Rake was expecting for a plugin. Maybe you have a similar problem where you didn't link / copy / check out the actual plugin directory like you thought you did.

I don't know how much, if at all, this will help you, but thought I'd toss my thoughts in here real quick.
