Solution

  • This does not appear to be a problem with openproject, but rather one with the railsinstaller version you are using. It will go away when you make sure you're using a ruby version above 1.9.3

    The openproject installation guide lists ruby 2.1 as a minimal requirement. Unfortunately it seems that there is no railsinstaller that provides a ruby above 1.9, that would render openproject incompatible with railsinstaller on your machine.
