Download statistics for package registered on Pypi can be obtained, in RSS format, by subscribing your favorite RSS reader (e.g. GoogleReader) with the following:
Q: I tried http://www.jldupont.com/services/pypirss/rss/lockfile but got an error. Does something need to be set up for each package?
A: There is no downloads available for this package, hence no statistics on downloads.
- ERROR: Error accessing "downloads" attribute from package[lockfile]
Q: You mean no downloads since you implemented this feature, or no downloads at all?
A: Sorry for the confusion: the XMLRPC interface to Pypi returns that an error code to the effect that no 'package_data' is available. If I look at the page on Pypi [http://pypi.python.org/pypi/lockfile], I don't see one either.
