Travis reports odd message of corrupted Gemfile.lock

Question

Im using bundler to install stuff and since I have added Gemfile.lock, travis started to complain with:

Your Gemfile.lock is corrupt. The follow         


        

Answer 1

Firstly, remove the gem lock file:

rm -f Gemfile.lock

Then install the dependencies:

bundle install

You can update the dependencies to ensure that you won't get an error:

bundle update

Answer 2

We've seen a very similar issue today on Buildkite due to the recent release of a new bundler version https://rubygems.org/gems/bundler/versions/1.11.0

We got the build working by stipulating the version of bundler to install.

gem install -v 1.10.6 bundler --no-rdoc --no-ri

and forcing the use of that

bundle _1.10.6_ install
