The files in the fileconveyor directories are all owned and grouped by root (and I am logged in as root), they are 644 (although I also tried 755 just in case there was an executable issue with the subdirectories).

I don't understand why it isn't finding the transporter_sftp.py module. I've looked through other issues with this same error, but none of their fixes work for me.

I installed using:

pip install -e git+https://github.com/wimleers/fileconveyor@master#egg=fileconveyor

I was able to use the symlink_or_copy transporter, but still not able to use the sftp transporter.

I'm an experienced dev, but I know nothing about python, django, etc. However, it looks to me like the transporter_sftp simply doesn't work at all with the current version of SFTPStorage.

I was able to get the sftp transporter recognized after I yum installed python-paramiko, and then the next error message I received was that the SFTPStorage init method expects only 1 param, but 4 were given. I dug into the SFTPStorage code and it looks like it grabs all of its configuration variables from a class called django.conf.settings, but that's not at all how the sftp transporter expects to be sending those variables.
