Redmine requires Bundler 1.5.0 or higher (you’re using 1.3.5)
sudo gem install bundler
bundle install –without development test
sudo gem update
$ sudo gem install bundler
To upgrade to RubyGems 1.5.0, run:
gem update –system
Solution which worked
I had the same problem today, and it was solved by removing the debian bundler package: apt-get remove bundler
After that “ruby bin/rails server -e production” complained about a missing gem “yard”, but after the suggested “bundle install” it worked.
It seems that calling bundle from within ruby uses a different bundler ?!
HTH Beat
