Hi, I’ve on [hostmonster.com](http://hostmonster.com) and i’ve run into a small problem that I  
just can’t get. When I push my application into my hosting environment  
and try to run rake db:migrate, I get an error message from rake  
telling me to install the missing gem my environment.rb file has:

config.gem “formtastic”  
config.gem “authlogic”

So I installed them but I still get the same error. I’ve no clue as to  
whether this is a hostmonster problem or something in a rails script  
or configuration file that I’m overlooking.

I also found a gem called gemsonrails. So I was thinking if I link my  
gems to my application, then push it onto my hosting providor, I won’t  
need to manually install gems then? Does anyone have any experience  
with gemsonrails?

Thanks

Most likely your application is looking for the gems at the server  
level rather than the user level. Here’s a KB article from  
[hostmonster.com](http://hostmonster.com) describing what you need to do:

Hey thanks for the heads up!

I couldn’t figure out what to put in the ENV[‘GEM\_PATH’], I tried  
ENV[‘GEM\_PATH’]  
= ‘$GEM\_HOME:/usr/lib/ruby/gems/1.8’ but I was still getting the error.

I used rake gems:unpack in my application and then pushed it onto the  
server  
and that seems to work fine. I’m a little annoyed that it wasn’t working  
more naturally with the paths and stuff though.

Cheers

You can get this error sometimes if there’s a dependency missing (for  
formtastic or authlogic). If possible, try running ‘rake gems’ and  
look for entries that aren’t installed.

Gemsonrails hasn’t been maintained for some time (late 2008) and is  
now incompatible with Rubygems 1.3.7 (gets an error when unpacking).
