Problem with plugin installation

[JanSykor]

Hello
I have problem with installation of this plugin. During installation I received next error.
There is no matter if installation starting from Octoprint or over SSH.
I think that problem is some rights adjustment, but I can´t find what is wrong.

Instalace pluginu "Email Notifier" z https://github.com/anoved/OctoPrint-EmailNotifier/archive/master.zip... /home/pi/OctoPrint/venv/bin/pip install

My installation is on RPi3 + Raspbian + Octoprint installed by this link:
https://github.com/foosel/OctoPrint/wiki/Setup-on-a-Raspberry-Pi-running-Raspbian

Other plugins was installed correctly.
Do you have somebody any ideas how to repair, please?

Thanks
Jan

Thanks for the report. I am quite behind in updating projects and will need to study the OctoPrint plugin system again before I can fix this. I'll post an update here when I do.

Consolidating in to issue #24. Thanks for the installation link. That may be helpful info as I use OctoPi (Raspbian + OctoPrint distributed as a prepared SD image). Perhaps OctoPi bundles some prerequisite packages that are problematic to install in ad hoc OctoPrint systems?
