Error during setup on OctoPrint 1.3

[Rus5]

I was not able to install plugin on updated OctoPrint v 1.3

Part of error log is the following

Thanks for the report. I'm just getting back in the swing of things debugging this and need some help understanding how this attempted installation was initiated. Most of the errors I see in this report are related to packages (cffi and cryptography) not explicitly required by this plugin. I presume they are indirect prerequisites of yagmail or keyring, but it's not clear.

Installing collected packages: cffi, cryptography, secretstorage, keyring, yagmail, keyrings.alt, OctoPrint-EmailNotifier

Can you provide a little more information about the kind of system you're working with (Raspbian?) and exactly how you tried installing it? My first step is to determine how the problematic packages are related to EmailNotifier and at what point in the installation process they were collected. Thanks for your help.

This does look like the same issue reported in #22:

Command "/home/pi/OctoPrint/venv/bin/python2 -u -c "import setuptools, tokenize;file='/tmp/pip-build-tnHXkv/cffi/setup.py';f=getattr(tokenize, 'open', open)(file);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, file, 'exec'))" install --record /tmp/pip-9eqCPh-record/install-record.txt --single-version-externally-managed --compile --install-headers /home/pi/OctoPrint/venv/include/site/python2.7/cffi" failed with error code 1 in /tmp/pip-build-tnHXkv/cffi/

This also looks like the issue reported in #20.

I'm guessing the problem may be related to differences between OctoPi systems (which is what I use) and OctoPrint systems installed by hand (as per this guide). Perhaps there are permissions or pre-installed package differences that account for difficulties in one case but not the other.

Can anyone corroborate this theory?
