Setup docs - Install bundler with specific version
Previously gem install bundler
would install bundler version 2.x (at
time of writing), resulting in this error during gdk install
(specifically the step cd path/to/gitlab && bundle install --jobs 4 --without production --without mysql
):
can't find gem bundler (>= 0.a) with executable bundle (Gem::GemNotFoundException)
This fix asks the user to install the same version of bundler that is in
Gemfile.lock
.
