Installation on existing raspbian
Installation from source
see the five steps described in the "Installing from source" section of
Installing Python3 including pip and virtual env
python3 --version
Python 3.7.3
pip3 install virtualenv
...
Collecting virtualenv
...
Successfully installed distlib-0.3.1 filelock-3.0.12 virtualenv-20.2.1
virtualenv will not be available via command line at this point so the instructions from the forum article will provide virtualenv.
sudo apt install python3-pip python3-dev python-setuptools python-virtualenv git libyaml-dev build-essential
Obtaining the octoprint source
git clone https://github.com/foosel/OctoPrint.git
Creating a virtual environment
wf@pito:~/source/python/OctoPrint $ virtualenv venv
Running virtualenv with interpreter /usr/bin/python2
New python executable in /home/wf/source/python/OctoPrint/venv/bin/python2
Also creating executable in /home/wf/source/python/OctoPrint/venv/bin/python
Installing setuptools, pkg_resources, pip, wheel...done.
Installing OctoPrint into that virtual environment
wf@pito:~/source/python/OctoPrint $ ./venv/bin/python setup.py install
...
Using /home/wf/OctoPrint/venv/lib/python3.7/site-packages
Finished processing dependencies for OctoPrint==1.5.1
Start OctoPrint Server
./venv/bin/octoprint serve
Finish Install via Webbrowser
Octoprint listens on port 5000 by default:
http://<octoprintserver>:5000/
