Redmine requires Bundler 1.5.0 or higher (you re using 1.3.5) Blog

July 15, 2021 . 1 MIN READ

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
