Question

I’ve recently started looking at Merb, for use with some small projects around the office. I’m trying to set up my first project following the docs, and am encountering an exception such as:

foo:beta user$ merb
Merb root at: /Users/user/code/merb/beta
Loading init file from ./config/init.rb
Loading ./config/environments/development.rb
 ~ Connecting to database...
 ~ Loaded slice 'MerbAuthSlicePassword' ...
 ~ Parent pid: 39794
 ~ Compiling routes...
 ~ Activating slice 'MerbAuthSlicePassword' ...
 ~ 
 ~ FATAL: Mongrel is not installed, but you are trying to use it. You need to either install mongrel or a different Ruby web server, like thin.

I have installed Mongrel from gem as well as from MacPorts, and am confused by this exception.

Significant stats:

ruby 1.8.7 (2010-01-10 patchlevel 249) [i686-darwin10]

From my installed gems:

merb (1.1.0)
merb-action-args (1.1.0)
merb-assets (1.1.0)
merb-auth (1.1.0)
merb-auth-core (1.1.0)
merb-auth-more (1.1.0)
merb-auth-slice-password (1.1.0)
merb-cache (1.1.0)
merb-core (1.1.0)
merb-exceptions (1.1.0)
merb-gen (1.1.0)
merb-haml (1.1.0)
merb-helpers (1.1.0)
merb-mailer (1.1.0)
merb-param-protection (1.1.0)
merb-slices (1.1.0)
merb_datamapper (1.1.0)
mongrel (1.1.5)

Merb documentation is non-existent, so I find myself stuck.

Thanks in advance.

mongrel is quite outdated and doesn’t always work with newer rubys. If thin doesn’t work either try using webrick (merb -a webrick). That’s the default server on ruby, and should work fine (albeit it’s the slowest of all)
