Installing on OSX fails

[markstar]

I've been able to install juicer on Windows perfectly okay. However, it's not working on OSX. Even with the following command: sudo gem install juicer --include-dependencies

I get the following error:

INFO: gem install -y is now default and will be removed INFO: use --ignore-dependencies to install only the gems you list Building native extensions. This could take a while... ERROR: Error installing juicer: ERROR: Failed to build gem native extension.

Looks like the problem is with libxml, which Juicer depends on.

[markstar]

Thanks for getting back to me. So is this an issue with my version of libxml? Or is it a dependency that's missing? I used the --include-dependencies flag when installing so I would expect them all to be installed as part of the install process. Or is this not the case?

[cjohansen]

AFAICT, it's failing to build the libxml bindings because the development files (the header file listed in the error output) cannot be found. I have no idea how to solve it on a Mac. You can reproduce by simply trying gem install nokogiri

Same issue with Ubuntu. Installing Nokogiri helped. http://nokogiri.org/tutorials/installing_nokogiri.html
