ruby - Install newer version of bundler with bundler

Question

If I change the version of bundler required in a Gemfile, and then type bundle, I get

Bundler could not find compatible versions for gem "bundler":
  In Gemfile:
    bundler (>= 1.10.2) ruby

  Current Bundler version:
    bundler (1.9.9)
This Gemfile requires a different version of Bundler.
Perhaps you need to update Bundler by running `gem install bundler`?
Could not find gem 'bundler (>= 1.10.2) ruby in any of the sources

Is it possible to ask bundler to install the new version of bundler, rather than typing in gem install bundler?

Answer 1

Seems like bundler can't bundle itself :)

So you have to run gem install bundler.
