OctoPi plugin

[Jeff Hennigar]

Hello! I'm an elementary school teacher here in Halifax, and I'm in over my head with OctoPrint. 

I recently received a grant for some Polar3D printers and access to Polar Cloud. I'd love to get my SeeMeCNC Orion Delta also working through the Polar Cloud for my students. I'm having some trouble installing the Polar Cloud Plugin for OctoPrint. I'm using a RPi 2, and I have OctoPrint installed and working correctly. I get the error on installation: "Could not parse the output from pip". I followed all the options that I could find on this thread without any luck. https://github.com/markwal/OctoPrint-PolarCloud/issues/10

Do you have any advice for me? I'm new to Raspberry Pi and python... Any help is appreciated!

[Patrick McGuire]

Can you start by running "'pip -V" in the terminal?

Thanks

Just tried, It asks for a password, and my password for the Pi doesn't work...

[Patrick McGuire]

Maybe try as root? "sudo -i" first

[Patrick McGuire]

if pip is not responding with a version maybe  "sudo apt install python-pip"

[Jeff Hennigar]

got it

pip 9.0.1 from /usr/local/lib/python2.7/dist-packages (python 2.7)

[Patrick McGuire]

Awesome, how about the output right before the error, maybe 10 to 20 lines of output?

[Patrick McGuire]

I think it wants Python 3 not 2, both can be installed at the same time so it is confusing.

http://docs.python-guide.org/en/latest/starting/install3/linux/

based on  "Invalid environment marker: python_version < '3'"

[Patrick McGuire]

Interesting.. maybe try 

" pip install pyopenssl"

http://pyopenssl.org/en/stable/install.html

[Jeff Hennigar]

Ok, So it does have both installed. 3.2.4 and 2.7.9

I'm not sure what to try from that doc. Does OctoPrint use Ubuntu?

[Patrick McGuire]

Python and Javascript

[Jeff Hennigar]

"Requirement already satisfied: pyopenssl in /usr/lib/python2.7/dist-packages"

[Patrick McGuire]

This may be close

https://github.com/ansible/ansible/issues/31741

[Patrick McGuire]

sudo pip install --upgrade setuptools
sudo apt-get install libffi-dev libssl-dev

[Patrick McGuire]

If that doesn't help what is the output from

sudo pip install pillow

[Jeff Hennigar]

The setuptools update did it! Thank you!
