Installing Redmine and Rails3

Clone Toshi MARUYAMA’s Redmine repo https://github.com/marutosi/redmine.git

Try to run redmine application:

   ./script/rails server

If you see the following error:

   config/boot.rb:1:in `require': no such file to load -- rubygems (LoadError)

install ruby1.9.1, delete any previous version.

   sudo apt-get install ruby1.9.1
    sudo apt-get remove ruby1.8

try again

   ./script/rails server

If you see the following error:

   config/boot.rb:14:in `rescue in <top (required)>': uninitialized constant        Object::Bundler (NameError)

You should install bundler

  sudo gem install bundler

Now you’ll end up with following error:

   Could not find gem 'rails (= 3.2.1) ruby' in any of the gem sources listed in your Gemfile.
    Try running `bundle install`.

Do like they said:

   bundle install

Now you have this error:

   Installing json (1.6.5) with native extensions 
    Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.
/usr/bin/ruby1.9.1 extconf.rb 
<internal:lib/rubygems/custom_require>:29:in `require': no such file to load -- mkmf (LoadError)
	from <internal:lib/rubygems/custom_require>:29:in `require'
	from extconf.rb:1:in `<main>'

Ok, gem was trying to build a native extension and failed. This is because ruby1.9.1-dev is not installed. Try now

   sudo apt-get install ruby1.9.1-dev

And again

   bundle install

Now we have another error:

Installing mysql (2.8.1) with native extensions 
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

This is fixable by installing sudo libmysqlclient-dev:

   sudo apt-get install libmysqlclient-dev

And again!

   bundle install

Error again:

   Installing pg (0.9.0) with native extensions 
    Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

We are losing patience now. Fix by installing  libpq-dev

   sudo apt-get install libpq-dev

At last!

   Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed.

Try running again:

   ./script/rails server

Complains about missing config/database.yml


Setup your database

    cp config/database.yml.example config/database.yml

My file looks like this:

   production:
      adapter: sqlite3
      database: db/redmine.sqlite3

Run server:

    ./script/rails server

<p>Now server runs but opening redmine in browser shows Could not find table &#8216;settings&#8216;<br />

This is because we didn’t initialize our database yet.

Initialize the database:

   rake db:migrate

Now when we start again

    ./script/rails server

we’ll see redmine index page.
