Rails + Travis CI: Bundler cache?

Question

Ruby on Rails

The problem is this: Every time you run tests on Travis CI , the system re-installs all the necessary gems, which greatly slows down the process.
The .travis.yml contains the following lines:

cache:
  bundler: true

However, this doesn't help.
How to be?

Answer 1

I don't know......it's just a guess.....but can bundler: false try?
