Control bundle config through pkgr?

[mdr]

I'm trying to package my Rails app that depends on nokogiri. Apparently Bundler needs special configuration to build on my Ubuntu 14.04 VM:

bundle config build.nokogiri "--use-system-libraries --with-xml2-include=/usr/include/libxml2"

Can I control that through pkgr? Otherwise it fails:

Hello,

I was able to do this using bundler's --local option. This option writes the config in the app directory so pkgr will have access to it.

Try this:

bundle config --local build.nokogiri "--use-system-libraries --with-xml2-include=/usr/include/libxml2"

[mdr]

Thanks, that works a treat!

Thanks for the tip @luizsignorelli !

Was there any way of controlling this through .pkgr.yml? The problem is that running that on my Debian build server doesn't make any difference - I get the same error. And if I set it in the repository, it'll affect my OS X development machine.

[andyjeffries]

Even leaving out the --local when running the bundle config command on the build machine doesn't work (I don't know if anyone would expect it to).

@andyjeffries I suppose you could run that command as a before step in the .pkgr.yml file, so that it gets run on the build machine?

before:
  - bundle config --local build.nokogiri "--use-system-libraries --with-xml2-include=/usr/include/libxml2"
