The recommended way to handle dependencies using setuptools is to specify them in the install_requires metadata in the setup() function call in your setup.py: # http://peak.telecommunity.com/DevCenter/setuptools#basic-use setup(name="foo", ... install_requires = [ 'some_package >= 1.0', 'another_package', ], ) However, if you have special needs that really do require downloading the dependency at runtime instead of install-time: # http://peak.telecommunity.com/DevCenter/PkgResources#workingset-methods-and-attributes import pkg_resources pkg_resources.resolve('some_package >= 1.0') pkg_resources.resolve('another_package') import some_package import another_package But, please be sure that that your needs are special. -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco -- http://mail.python.org/mailman/listinfo/python-list
