How: followed installation instructions (apt reported successful installation) What: I get the following error when i type in cassandra-snapshotter --help ubuntu@vsk01:~$ cassandra-snapshotter --help Traceback (most recent call last): File "/usr/local/bin/cassandra-snapshotter", line 5, in from pkg_resources import load_entry_point File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 2749, in working_set = WorkingSet._build_master() File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 444, in _build_master ws.require(requires) File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 725, in require needed = self.resolve(parse_requirements(requirements)) File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 628, in resolve raise DistributionNotFound(req) pkg_resources.DistributionNotFound: ecdsa>=0.11

What is ecdsa and why is this dependency not met ? Thanks!

I fixed it. Turns out some old version was installed by distutils (I think this should be made aware) Fix was to (a) uninstall cassandra-snapshotter (sudo pip uninstall cassandra-snapshotter)

and reinstall.. pulled the right dependencies.

Running setup.py install for cassandra-snapshotter Found existing installation: ecdsa 0.10 DEPRECATION: Uninstalling a distutils installed project (ecdsa) has been deprecated and will be removed in a future version. This is due to the fact that uninstalling a distutils project will only partially uninstall the project. Uninstalling ecdsa-0.10: Successfully uninstalled ecdsa-0.10 Running setup.py install for pycrypto
