Some worker preinstalled ffi gem, CAUSE: RubyPython::PyObject::FFI (NameError)

[saberma]

Here is the error report from my test app

http://travis-ci.org/#!/saberma/test-travis-ci-xvfb/jobs/1390501/L121

Only happen in this workers:

• ruby1.worker.travis-ci.org:travis-ruby-1
• ruby1.worker.travis-ci.org:travis-ruby-3
• ruby1.worker.travis-ci.org:travis-ruby-6

Pygments.rb requires pygments to be installed. Try adding this to your .travis.yml file:

before_install:
  - sudo apt-get update
  - sudo apt-get install python-pygments

[saberma]

@dvyjones Thanks for your reply, I have added the before install script, but error is the same.

[sarahhodne]

Oh, duh. You need libpython too. Sorry about that:

before_install:
  - sudo apt-get update
  - sudo apt-get install libpython2.7 python-pygments

[saberma]

Does all the ruby workers use the same configurations?
What I saw is the same rails app run in different workers, but the result is also difference.

Please take a look at build result(6 pass, 3 fail):

@dvyjones I'm try to install libpython, but indicating its already installed.

libpython2.7 is already the newest version.

[sarahhodne]

They should be exactly the same. @michaelklishin, can you take a look at this? (granted I remember who works on what)

[michaelklishin]

Ruby MVs are not all upgraded all at once. What you are seeing is 2 machines already upgraded and 2 are not.

[michaelklishin]

Uninstall whatever version of the ffi gem does not work with your project in a before_install and install the one you need.

[michaelklishin]

New images will be deployed within 24 hours.
