ImportError: No module named version

I have installed python beaver package and wanted to install elasticsearch-curator. That's when I encountered this error:

File "/usr/lib64/python2.6/distutils/dist.py", line 975, in run_commands

        self.run_command(cmd)

      File "/usr/lib64/python2.6/distutils/dist.py", line 995, in run_command

        cmd_obj.run()

      File "<string>", line 12, in replacement_run

      File "/usr/lib/python2.6/site-packages/pkg_resources/__init__.py", line 2310, in load

        return self.resolve()

      File "/usr/lib/python2.6/site-packages/pkg_resources/__init__.py", line 2316, in resolve

        module = __import__(self.module_name, fromlist=['__name__'], level=0)

    ImportError: No module named version

It turned out that python-daemon package with the culprit!

To get rid of, do the following:
    # pip uninstall python-daemon
    # pip install python-daemon
  
    If you wish, you may install specific version also, say
    # pip install python-daemon==1.6.1
    # pip install beaver --upgrade
    # pip install elasticsearch-curator
