easy_install_package remote tarball installation


#1

On the command line I can do the following and it works!

sudo easy_install
http://launchpad.net/graphite/1.0/0.9.8/+download/whisper-0.9.8.tar.gz

The corresponding resource definition fails.

easy_install_package “
http://launchpad.net/graphite/1.0/0.9.8/+download/whisper-0.9.8.tar.gz” do
action :install
end

INFO: Processing easy_install_package[
http://launchpad.net/graphite/1.0/0.9.8/+download/whisper-0.9.8.tar.gz]
action install (graphite::default line 16)


FATAL: Chef::Exceptions::package: easy_install_package[

(graphite::default line 16) had an error: No version specified, and no
candidate version available for
http://launchpad.net/graphite/1.0/0.9.8/+download/whisper-0.9.8.tar.gz

Is this expected? Is there a way to install a python package this way? I
can’t seem to find one.

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 :smiley:

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.

Kevin, you can work around it by checking explicitly for the egg file.

It’s not very cross platform.

I got that from Darrin’s graphite cookbook btw.
