"no such file to load -- dispatcher (LoadError)" on starting mongrel process

#1

After I updated to Rails 3.0, I encountered the following error on
booting mongrel process.
Can anyone advise? Thank you.

Hej Ryo,

have you added mongrel to your gems?

If not simply add “gem mongrel” to your Gemfile.

“rails server” will then automatically use mongrel.

Best,

Sebastian
