Your Ruby installation is missing a header file /usr/lib/ruby/include/ruby.h and can't compile FFI. Strictly speaking, this is not a problem with travis.rb.

the-ashh commented 7 years ago

ok then. do you have any suggestion to be able to fix this

BanzaiMan commented 7 years ago

@cooler9711 You'll need to have a working Ruby environment. If it's Ubuntu, for example, we have https://github.com/travis-ci/travis.rb#ubuntu. For other distros, I suspect the issue is similar; find a package that provides the header file you need to compile FFI.

Not to necro this, but since it's still open and google sent me here for this error initially:

As BanzaiMan pointed out, this problem happens when the ruby header files are missing. These exist in a separate package from the base ruby install, making it possible to have a "working" Ruby environment, but not able to compile extension modules. These headers exist in a -dev package for Debian / Ubuntu, and can be installed with:

sudo apt-get install ruby-dev

This is mentioned (without the accompanying error) in the main readme under Troubleshooting > Ubuntu (https://github.com/travis-ci/travis.rb#ubuntu)

I confirmed installing the above package resolved the problem posted for me, and this issue is probably safe to be closed.
