OpenSSL support for Ruby: "Cipher is not a module (TypeError)"

  • 772

The Problem

Our systems admin needed to upgrade the packages on our CentOS 5.4 dev server to match the packages on our production server. The upgrade affected ruby and/or openssl.

We run a Ruby on Rails issue tracking system called Redmine that is deployed with Passenger on Apache. Everything worked before the server update, but when trying to access the ticket system now, I get the following error:

Error message:

Cipher is not a module

Exception class:

TypeError

Application root:

/home/dev/rails/redmine-0.8.7

I've been trying so hard to fix this problem but I can't seem to beat it.

I have tried following this guide:
http://iamclovin.posterous.com/how-to-solve-the-cipher-is-not-a-module-error

When I try require 'openssl' in IRB, I do see a true return value. However, I'm still seeing the Cipher.rb is not a module TypeError when accessing the ticket system.

Possibly (probably) related:

I've tried updating Passenger, but when I try passenger-install-apache2-module I see:

Checking for required software...

* GNU C++ compiler... found at /usr/bin/g++
* Ruby development headers... found
* OpenSSL support for Ruby... /usr/lib/ruby/1.8/openssl/cipher.rb:22: Cipher is not a module (TypeError)

Any help?

    ruby 1.8.7 (2009-12-24 patchlevel 248) [x86_64-linux]

    in ruby source directory

    cd ext/openssl/
ruby extconf.rb 
make
sudo make install
sudo cp -R /usr/local/lib/ruby/site_ruby/1.8/openssl* /usr/lib/ruby/1.8/

    Finding a fix for this took a very long time...
