Bundler / Passenger strange deployment Issue

Today I tried to deploy our Ruby on Rails application. Environment: Passenger with Ruby on Rails 1.9.3 (via system-wide-rvm) on FreeBSD. Deployment via a simple capistrano script.

After a successful capistano deploy I get the following error when trying to view it in the browser:

Web application could not be started

Could not find rake-10.1.0 in any of the sources (Bundler::GemNotFound)
  /usr/local/rvm/gems/ruby-1.9.3-p392@generalrails/gems/bundler-1.3.5/lib/bundler/spec_set.rb:92:in `block in materialize'

  /usr/local/rvm/gems/ruby-1.9.3-p392@generalrails/gems/bundler-1.3.5/lib/bundler/environment.rb:18:in `requested_specs'

When I run rake --version in the selected rvm-environment it just exists.
After searching for while I found the following problem:

Passenger gave the following GEM home:

GEM_HOME = /var/usr/local/www/https_www.webpathy.eu/shared/bundle/ruby/1.9.1

When I look in the directory "shared/bundle/ruby" I see everyting is deployed in a directory named: 1.9. The 1.9.1 directory is completely empty!

That's not going to work
WTF!

My quick work-around is the following: 

ln -s 1.9 1.9.1

Now it's running again...
Does anybody know why bundler first deploys it all in "bundle/ruby/1.9" and passenger tries to grab it from "bundle/ruby/1.9" ?!?!?

Installing Ruby on Rails with Mysql on Windows

No I don't like working on Windows, but unfortunately my co-workers haven't seen the light yet.

To make the rails setup a bit easier I needed to document the installation of Ruby on Rails on Windows with a Mysql database.
The description is about Ruby 1.9.?, Rails 3.0, Mysql 5.5 with the mysql2 gem.. and a lot of gems that got installed and compiled via "bundle install"

Here's a raw extract of the document I build:

1. Install MySQL

In our situation MySQL was installed. But you should install MySQL with development files. (C++ headers and Libraries).
Just download the Community Server at http://mysql.com/.

2. Install Ruby

Install the base Ruby version. Download the installer at http://rubyinstaller.org/
Run the installer and check the following items:

  • Add Ruby executables to your PATH
  • Associate .rb and .rbw files with this Ruby Installation

3. Install DevKit

Because a lot of Ruby plugins make use of Native extensions you need a compiler. For windows there's devkit to the rescue. Download it at rubyinstaller: http://rubyinstaller.org/.

Extract this to (for example) c:/devkit (this text assumes this location)
Open a command prompt: (cmd.exe) and enter the following commands.

cd c:/devkit 
ruby dk.rb init

DevKit wil probably find your ruby installation. But to make sure check the file c:/devkit/config.yml. It should contain the path of your Ruby installation:

--- 
- C:/Ruby192

This step installs (or updates) an operating_system.rb file into the relevant directory needed to implement a RubyGems pre_install hook and a devkit.rb helper library file into \lib\ruby\site_ruby. NOTE: you may need to use the –force option to update (with backup of the originals) the above mentioned files as discussed at the SFX DevKit upgrade FAQ entry.

Test the Devkit installation Confirm your Ruby environment is correctly using the DevKit by running.

gem install rdiscount --platform=ruby

RDiscount should install correctly and you should see:

Temporarily enhancing PATH to include DevKit... in the screen messages.

After this double check if it works by running:

ruby -rubygems -e "require 'rdiscount'; puts RDiscount.new('**Hello RubyInstaller**').to_html"

to confirm that the rdiscount gem is working. (This should generate HTML)
(More info: https://github.com/oneclick/rubyinstaller/wiki/Development-Kit )

4. Install Git

If you not already have installed git, please do it. You will like it!
Git is required for many plugins so you need it.

  • download git at http://code.google.com/p/msysgit/ (choose a version I don't know :P, the latest .exe ?? )
  • execute the installer, select the following options:
    • check “Run Git and included tools from the windows command prompt” (Select the option with the red letters that scream "don't pick me" :P )
    • checkout-as-is and commit-as-it.

5. Install Rails with the mysql2 plugin

Next install Ruby on Rails. (We don't install/generate the docs)

gem install rails --no-ri --no-rdoc

6. Install the mysql2 gem

To build mysql2 support do this: (Point the paths to your MySQL install directory!)

NOTE: When using a 64bit version of windows you probably run into issues. Thanks for mentioning Luis! (Read more about it: http://blog.mmediasys.com/2011/07/07/installing-mysql-on-windows-7-x64-and-using-ruby-with-it/ ).

gem install mysql2 -- '--with-mysql-lib="c:\Program Files\MySQL\MySQL Server 5.5\lib" --with-mysql-include="c:\Program Files\MySQL\MySQL Server 5.5\include"'

(Mysql5.1 seems to have the path: c:\Program Files\MySQL\MySQL Server 5.1\lib\opt)

Fix up Bundler (the gem management tool) to know what the mysql2 gem build settings need to be..
Else you're "bundle install" will fail when installing or updating the mysql2 gem!!

bundle config build.mysql2 '--with-mysql-lib="c:\Program Files\MySQL\MySQL Server 5.5\lib" --with-mysql-include="c:\Program Files\MySQL\MySQL Server 5.5\include"'

As soon as you start using this installation you could get errors like 'libmysql.dll not found.
To solve this copy this file from the mysql-installation/lib directory to the ruby/bin directory.

Slightly Unrelated, install the Rails app

Pull the rails app from git. (Or copy it). And run bundler install to install all gems..

cd /rails/app
bundle install

I've recieved the following error when doing this:

Resolving deltas: 100% (3434/3434), done.
Checking out files: 100% (85/85), done.
Fetching source index for http://rubygems.org/

Could not find devise-1.4.0 in any of the sources

I seems that devise was updated and the specific version in Gemfile.lock wasn't available anymore.
You can Force the installation of this updated package

bundle update devise

These were my steps to build a working rails environment under windows...
Enough of windows, Now back to my Mac :P
