I had bundler 1.16 installed and rails was complaining that my bundle had previously been created with a higher version of bundler So I installed bundler 2.0.1 with the --default switch but that still left a default 1.16.6 as well I'm trying to uninstall 1.16.6 but I get error can't uninstall a default gem How can I remove it's default flag then? Also if I'm using rails 5.0.7 which ruby version should I use?

I am not sure if this is the right way to do this, but, in my case, its how i got the issue fixed. So, just in-case this helps.
Initially:
gem list bundler
*** LOCAL GEMS ***
bundler (default: 2.0.2, default: 1.17.3, default: 1.16.6)
bundler-unload (1.0.2)
rubygems-bundler (1.4.5)
After failing multiple uninstalls, I ran this,
gem update --system
Then,
bundle version
Bundler version 1.17.3 (2019-08-16 commit d7089abb6)
(which is the version i required in my application)
gem list bundler
*** LOCAL GEMS ***
bundler (default: 1.17.3)
bundler-unload (1.0.2)
rubygems-bundler (1.4.5)
If you really, really want to remove the default bundler, you can clobber it like I just did using something like this but adjusted for your ruby's versions and paths:
rm /usr/local/rbenv/versions/2.6.2/lib/ruby/2.6.0/bundler.rb
rm -r /usr/local/rbenv/versions/2.6.2/lib/ruby/2.6.0/bundler/
rm /usr/local/rbenv/versions/2.6.2/bin/bundle{,r}
rm /usr/local/rbenv/versions/2.6.2/lib/ruby/gems/2.6.0/specifications/default/bundler-1.17.3.gemspec
Or, living dangerously:
rm -rf "$(ruby -e 'print RbConfig::CONFIG["rubylibdir"]')"/bundler{.rb,/} \
"$(ruby -e 'print RbConfig::CONFIG["bindir"]')"/bundle{,r} \
"$(ruby -e 'print Gem.dir')"/specifications/default/bundler-*.gemspec
I ran into the same problem. None of the suggested answers worked for me. Then I tried to install bundler again -- issue solved.
gem install bundler
hope it works for you too.
Try
gem list -d
command to see the gems then use
gem uninstall bundler -v 1.16.6
or
gem uninstall bundler -v 1.16.6 --default
