"You must use Bundler 2 or greater..." Error
ruby 2.6.1p33 (2019-01-30 revision 66950) [x86_64-linux]
Bundler version 2.0.1
On creating a new app and trying
rake db:create i get:
You must use Bundler 2 or greater with this lockfile. even after deleting the lockfile and re-running
bundle install or
bundle update I get the same thing. The only way to make it work is to run
bundle exec rake db:create. But then, to run migrations it will just keep getting the same error message.
Try upgrading to Ruby 2.6.3 (it's the latest version anyways).
There was an issue in Ruby core that they mentioned here in this discussion about the issue. https://github.com/bundler/bundler/issues/6937
This Bundler 2 stuff has been an absolute mess.
