Run Capybara-Webkit tests in Travis-CI

what is the rest of your .travis,yml?

/usr/bin/xvfb-run: 182: /usr/bin/xvfb-run: rspec: not found
The command "xvfb-run rspec" exited with 127.

it should be something like this script:- xvfb-run bundle exec rspec spec/features/*.rb

same error for me
/usr/bin/xvfb-run: rspec: not found

This post and @ahmedattyah's suggestion helped fix my issue in Travis-CI. Thanks for sharing!

What worked for me (snippet of my travis.yml):

env:
  - TEST_DIRECTORY=spec/models
    SPEC_OPTS="--color --profile"
  - TEST_DIRECTORY=spec/classes
    SPEC_OPTS="--color --profile"
...
script: xvfb-run bundle exec rspec $TEST_DIRECTORY
