Hi there, as far as I know, gems can be stored in 2 folders: 1. /usr/lib/ruby/gems/1.8/gems 2. app/vendor/gems When I install a gem, it automatically goes into the 1st folder. My questions are: - What are the reasons one should store the gems in the 2nd folder (app/...)? - Does it have anything to do with deployment/"portability"? If yes, how? - How should gems be put in there? Any special command or is copy/paste OK? - Do apps automatically find the correct location of the gems? Any config to do? - How are gems in app/vendor/gems updated? Using the normal gem update command? Background info: - I''m pretty much a n00b - I plan to deploy my app to slicehost.com (unless you guys know better solutions) - At slicehost, I will have access to the entire OS (Ubuntu) Thanks for any help with this!

If you roll out some new code which means that for the first time your app requires gem blah you don''t need to remember to update/install that gem because it will just happen magically when your source code is checked out. It''s also handy if you don''t have the file system permissions to update the system gems. There are rake tasks supplied by rails for managing this stuff Fred> > Background info: > - I''m pretty much a n00b > - I plan to deploy my app to slicehost.com (unless you guys know better > solutions) > - At slicehost, I will have access to the entire OS (Ubuntu) > > Thanks for any help with this! > Tom > -- > Posted viahttp://www.ruby-forum.com/.
