I'd like to do something like this: http://python.pastebin.com/m283c0376 Basically, I'm invoking the easy_install command from a script. Where I specify a number ofn arguments to the --find-links option, some of which will be web-servers and at least one will be a local filesystem path, or possibly a network path un UNC format. It seems to work just fine when I do not provide a --find-links option (in this case it just picks up the defaults from distutils.cfg), when I use the option all I get is: Traceback (most recent call last): File "D:\workspace\pythonscripts_trunk\javapy_egg\Scripts\test_javapy.py", line 20, in ? result = pyproxy.requireEgg( eggspec , True, hosts ) File "d:\workspace\pythonscripts_trunk\javapy_egg\src\calyon\javapy\pyproxy.p y", line 141, in requireEgg pkg_resources.require(eggname) File "d:\python24\lib\site-packages\setuptools-0.6c9-py2.4.egg\pkg_resources. py", line 626, in require needed = self.resolve(parse_requirements(requirements)) File "d:\python24\lib\site-packages\setuptools-0.6c9-py2.4.egg\pkg_resources. py", line 524, in resolve raise DistributionNotFound(req) # XXX put more info here pkg_resources.DistributionNotFound: myproject==trunk-99 Can somebody confirm the correct way to do this? For example do I use Windows or UNIX slashes? What character must be used to seperate multiple URLs? I'm using setuptools 0.6c9 on Windows32 This email does not create a legal relationship between any member of the Crédit Agricole group and the recipient or constitute investment advice.
