Here's the error:

I already tried sudo gem install mongrel --pre and even the one that has --source

I don't know why it isn't working. Is it compatible with Ruby 1.9.1 and up?

回答1:

You are not alone. In the thread, however, there’s a link to a possible fix. I’ve not tried it so YMMV, but it seems like a plausible fix.

Given that Mongrel is no longer being updated, though, why not switch to something like Thin?

Edit: Sorry, I see that you're asking about 1.9.3. My understanding is that Mongrel is (supposed to be) compatible with up to 1.9.1, but broken in 1.9.2+. Yet another good reason to switch to something more modern and maintained.

回答2:

below command,

gem install mongrel --pre

works well.

ref: check this link for more details

回答3:

As John B stated, switch to Thin.

After not being able to get Mongrel to install with my current set up with Ruby 1.9.3, I commented out Mongrel from my Gemfile and added Thin. This let my app fully install and run great.

In my Gemfile

#gem 'mongrel', '1.2.0.pre2'
gem 'thin'

then run

bundle install
