Hello all,  
I’m have a problem starting Mongrel.

I get the following…

user-fc0e6f:ProjectDB johnmcleod$ script/server mongrel  
^C/Library/Ruby/Gems/1.8/gems/mongrel-1.1.5/lib/mongrel/gems.rb:11:in

`gem_original_require' from /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in`require’  
from script/server:3

I’m not sure where to go from here. I’ve uninstalled and reinstalled via  
“sudo gem install mongrel”

I have  
rack-1.0.0  
rack-1.0.1  
rack-1.1.0  
installed.

if that helps.

Thank you for any help with this.

Interrupt usually means that you killed it (eg control-C). DId you ?

Nothing?

You’re going to have to help us to help you:  
How are you trying to start it? (command line? in an IDE? in a script?)  
What gets displayed? (\*\* Starting Mongrel listening at 0.0.0.0:3000,  
etc)  
What OS are you on?!

Thank you for the reply.

Sorry about that.

OS: Mac

At the rails project root directory, using the Terminal, “script/server  
mongrel”.

When I say “nothing” I mean a blank screen. The cursor goes to the next  
line and that’s it.

I’ve also used “ruby script/server mongrel -debug” with the same  
results.

When I interrupt the process (CTRL+C), I’ve been getting this…

user-fc0e6f:ProjectDB johnmcleod$ ruby script/server mongrel -debug

Thank you for everyone’s reply.

I finally made it work.

Here’s the steps I did.

sudo gem uninstall mongrel  
sudo gem uninstall fastthread  
sudo gem install mongrel  
sudo gem install fastthread

As I’m not that experienced with this, I’ll assume that one or the other  
installation was bad.

I found the solution here:

Thanks again.
