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
bundle update --bundler

I had this same concern when trying to setup Bundler gem 2.2.11 as the default gem on my machine.

Here's how I achieved it:

First, I listed and uninstalled all other versions of the Bundler gem because I did not need them:

gem list bundler
gem uninstall bundler

If you encounter an error like this

Gem bundler-2.1.4 cannot be uninstalled because it is a default gem

Simply run the command below to get your ruby installation directory:

gem environment | grep "INSTALLATION DIRECTORY"

This should display an output like this. In my case my ruby version was 2.7.2:

- INSTALLATION DIRECTORY: /home/mycomputer/.rbenv/versions/2.7.2/lib/ruby/gems/2.7.0

Next, navigate to the specifications/default directory of the INSTALLATION PATH:

cd /home/mycomputer/.rbenv/versions/2.7.2/lib/ruby/gems/2.7.0/specifications/default

Remove/delete the bundler.gemspec file that you have there. In my case it was bundler-2.1.4.gemspec, so I ran the command:

rm bundler-2.1.4.gemspec

Next, I installed the Bundler gem 2.2.11 and made it the default gem:

gem install --default bundler -v 2.2.11

Next, I listed my Bundler versions:

gem list bundler

Finally, I updated my gems to use the newly installed Bundler:

gem update --system

That's all.

I hope this helps

You need to know where the default specs are, so use gem environment to find out.

the steps I used were:

gem environment
# note INSTALLATION DIRECTORY
cd <installation_dir>
cd specifications/default
rm bundler-2.1.4.gemspec
gem install --default bundler -v 2.2.11

You need to remove .spec file to remove the gem.

Steps:

  1. gem env – try to search in provided list under GEM PATHS, in specifications/default
  2. remove there bundler-VERSION.gemspec
  3. install bundler, if you don't have specific: gem install bundler:VERSION --default

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
