I am trying to install redmine 2.3.x on my Debian vServer. I already managed to build ruby from source and installed gems, rails and the apache passenger module. It should work until that point. I used the turotial at domainfactory: http://www.df.eu/de/service/df-faq/cloudserver/anleitungen/ruby-on-rails-installieren-debian-ubuntu/ .
After that I downloaded and extracted the redmine application as described here: http://www.redmine.org/projects/redmine/wiki/RedmineInstall#Installation-procedure. I created a mysql account and database, made a copy of the config/database.yml.example -> config/database.yml and filled in the correct values.
After that I installed bundler with
gem install bundler
And did go on with preparing the environment:
bundle install --without development test
All these commands did succeed.
After that I wanted to generate the secret token with the fallowing command:
rake generate_secret_token
The execution was interrupted with the fallowing message:
# rake generate_secret_token --trace
rake aborted!
cannot load such file -- mysql2/mysql2

I was trying to resolve this by checking versions and installed gems.
Ruby: ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-linux]
Rails: Rails 3.2.13
Gems: 1.8.25
Redmine: 2.3.3
I verified with gem list --local that the gem "mysql2" is installed.
gem "mysql": mysql2 (0.3.13)
As the problem seems to rely on this, I tried reinstalling the package, but this did not help.
What did I wrong here?
Thanks in advance, Sebastian Büttner
I found this error happens if you don't have the following package installed in your system (at least on Debian 9). So run command:
apt-get install default-libmysqlclient-dev
