Question

I’m first timer to Ruby on Rails, trying to set it up on RHEL 6. Since the package manager had very older version of Ruby. I compiled from source with Ruby 1.9.3 and installed rails using

$gem install rails

Created a new app using

$rails new /path/to/newapp

but now when I try to run

$rails server

it crashes with given log

    => Booting WEBrick
=> Rails 3.2.1 application starting in development on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server

I’ve tried to search about this error but did not find a working solution.

Apart from this I’d like to point me to some useful resource which explains best practices in Ruby on Rails.

Answer 1

I fixed the problem.

I went inside extracted source directory of Ruby then run these.

$cd /ext/openssl/
$ruby extconf.rb
$make
$make install

I hope other will get some help from this. 🙂
