[chef] Re: Re: easy_install_package remote tarball installation

[James < >]

I had to use easy_install for a client who has eggs but not .tar.gz's for some dependencies. Apparently PIP doesn't support eggs. I simply wrote an execute resource to handle this, wasn't aware that there was an easy_install_provider.

It looks like your syntax may be wrong, but I can't definitively find the syntax you should be using. It's probably some variation of: 

easy_install_package "whisper" do

  action :install

  version "0.9.8"

  options "-f http://launchpad.net/graphite/1.0/0.9.8/+download/whisper-0.9.8.tar.gz"

end

I think there was some progress on the idempotence problem [1] that Joe Williams did for 0.9.14. If you're using something less than that version, you may want to upgrade. 

Please post back what you find.

There is no way to do an idempotence check on such a thing (at least not easily) since Chef can't know what version of that package is installed currently. It could potentially be improved with either a manual package name attr or an understanding of the #egg= tagging, but any such fixes would go in the pip install provider since no one should be using easy_install anymore :-D
