Fix bundler error "can't find gem bundler (>= 0.a) with executable bundle"

can't find gem bundler (>= 0.a) with executable bundle

This error message seems to be related to network or Bundler issue, but it isn’t - newer version of Bundler requires new version of RubyGems, which is not updated by default.
To fix it, you’ll need to run:

gem update --system

This message should not bug you in the future :)


There is, or used to be a bug with rvm that installed newest bundler version for every ruby installed. It would install bundler v2, which requires ruby 2.3 or later. So if you're installing older ruby and keep getting similar errors, try deleting bundler and installing `~> 1.0` version
