Some gems seem to be missing from your vendor/cache directory.
Could not find rake-10.5.0 in any of the sources
The command "bundle install --local" failed and exited with 7 during .
Your build has been stopped.

I just want to remove this error, but am totally unfamiliar with Travis-ci. also i dont want to put any gems in vendor/cache because it will make repo so much bigger in size. any help on this?

Answer 1

by removing that line

install: bundle install --local

and putting cache: bundler and deleting those lines its worked!

  apt: true
  bundler: true
  directories:
  - vendor/cache
