Hi guys, I made a quick app for a family member to be deployed on Dreamhost (low budget). It’s my first time deploying on DH so I’m not familiar with the restrictions. I’m having an issue where I’ve been able to get git on both systems and used capistrano to deploy the app. However migrations fail. I also tried exporting my local staging mysql schema and importing it on the DH mysql database for production (same schema) and the site still fails to load. The only thing I can think of at the moment is that it is a gem issue. I haven’t used any gems knowingly, I’ve only used plugins (authlogic, enum-column, paperclip, searchlogic, and will\_paginate). However, some of these may use plugins (may) use gems. Anyone know of a way to get this info easily? OR… maybe it has nothing to do with gems?? Here is the passenger error page just in case, Any help is appreciated!!: A source file that the application requires, is missing. It is possible that you didn’t upload your application files correctly. Please check whether all your application files are uploaded. A required library may not installed. Please install all libraries that this application requires. Further information about the error may have been written to the application’s log file. Please check it in order to analyse the problem.

Have you tried to run rake gems:install on the server to install all required gems? ---

Now I’m trying to see my log files but having zero log (their freaking empty). Thanks. ---

for migrations, have you tried running rake db:migrate RAILS\_ENV=production ? That may or may not work. As far as the plugins go, you shouldnt need gems to make them work, or if you did you would only get an error when trying to use them. I believe paperclip does require ImageMagick though. You can see your gems if you type gem list –local in your terminal. If you contact Dreamhost they’ll probably be able to tell you more too. ---

Tried it with no luck. Waiting on DH to get back to me. Thanks again!
