How to change Bundler default version

问题

bundler (2.0.1, default: 1.17.2)

How could I change the default to 2.0.1

回答1:

What helped me is to delete the current default manually from the folder lib\ruby\gems\2.6.0\specifications\default\
and then install fresh bundler as usually
gem install bundler
or as default
gem install --default bundler

Following https://bundler.io/guides/bundler_2_upgrade.html#upgrading-applications-from-bundler-1-to-bundler-2, here's what worked for me:

gem install --default bundler
gem update --system
bundler update --bundler

回答3:

bundler config default 2.0.1

This should do it.
