I've installed a rails app (redmine) in my hosting provider. Bundle install completed successfully, but now I'm getting this error. Error message: There was an error while trying to load the gem 'mysql2'. (Bundler::GemRequireError) Exception class: PhusionPassenger::UnknownError Application root: /home1/deintem1/rails_apps/redmine3 Backtrace:

File Line Location:

Rails MySQL2 Error

Also tried 

gem install mysql2

and 

gem update mysql2

nothing worked.

Any ideas?

Environment:

rails -v

Rails 3.2.16

gem list | grep -i 'mysql2'

  • `gem install mysql2` worked without errors? You might want to check that the version you installed matches the version in the `Gemfile.lock`. You can get the version by `gem list | grep -i 'mysql2'`. – max Apr 16 '16 at 19:52
  • installed version of is mysql2 gem is 0.3.11, so version is different from Gemfile.lock, but how can I solve this, becasue "gem install mysql2" is correctly executed – Jack Casas Apr 16 '16 at 20:46
  • Have you tried `bundle update mysql2` yet? What (if any) version requirement do you have in your `Gemfile`? One plausible cause for this that comes to mind is if the MySQL client library is updated without rebuilding the gems C component. – Marcus Ilgner Apr 16 '16 at 23:04
  • bundle update mysql2 does execute without errors, but I still get the same error – Jack Casas Apr 17 '16 at 01:39
