At the hackathon earlier this month [ see: Legal Hacking 2018 ] I found several "areas for improvement" in the code underlying the developing BPD Watch . As I said I'd contribute, it made sense to set up a similar environment at home. After all, it's "just a database and some glue code" right?

> OpenOversight is released as free and open source software so others can launch similar police accountability projects in their own cities. The software is available for download on GitHub.
It sounded easy:
Developer Quickstart
Make sure you have Docker installed and then:
- git clone https://github.com/lucyparsons/OpenOversight.git
- cd OpenOversight
- make dev
- And open http://localhost:3000 in your favorite browser!
Only 4 steps. Oh, and a prerequisite. Which I didn't meet. Off to docker.org.
=
Note: If your system does not meet the requirements to run Docker for Windows, you can install Docker Toolbox, which uses Oracle Virtual Box instead of Hyper-V.
=
Ah, right, need to have Windows Professional
=
Requires Microsoft Windows 10 Professional or Enterprise 64-bit. For previous versions get Docker Toolbox.
=
So, fine, Docker Toolbox sounds good. Searching...

Hello from Docker!
This message shows that your installation appears to be working correctly.

Too easy, obviously. Trying out the first step (cloning with git),

$ git clone https://github.com/lucyparsons/OpenOversight.git
Cloning into 'OpenOversight'...
Erp.

MINGW64 /c/mingw64/[]/OpenOversight (develop)
$ make dev
bash: make: command not found
So, a running Linux flavor inside a Windows app, which doesn't have the bells and whistles of a full "tool chain" that needs must include make. Having read comments on hooking the Docker environment up to a CygWin install (which I already had) I diverted into a short cul de sac with apt-get (: command not found) then tried a cross-compile using the make from cygwin.

postgres uses an image, skipping

Pulling postgres

Postgres is up
## Creating database
= =
Sidebar - I had already looked at postgres for Cygwin, installed it on NetBSD, then decided the Windows version should be native, per some web hints. But I guess Docker doesn't know that database is running.
Next hurdle - building and populating the DB:
=
File "../create_db.py", line 2, in
from OpenOversight.app import create_app
ImportError: No module named OpenOversight.app
=
I had already installed Python with CygWin, and a native Windows version (and, as I later found, another python distro is bundled with LibreOffice).
=
$ ./create_db.py
bash: ./create_db.py: /usr/bin/python^M: bad interpreter: No such file or directory
CRLF conflict, can be overcome with an outer shell instead of running directly:
$ /c/cygwin64/bin/python3.6 create_db.py
$ pip3.6 install flask
ModuleNotFoundError: No module named 'flask_bootstrap'
ImportError: cannot import name 'config'
That last was due to Python 2/3 differences, I think, again "easily" fixed with a short edit
Back to the drawing board, and the bootstrap tools for Python and friends.
=
/cygdrive/c/mingw64/[]/OpenOversight
$ pip3.6 install -U pip setuptools
$ pip3.6 install python-dotenv
Collecting python-dotenv

More errors.

ERROR:

Well, no, I'm not sure I'm in the right directory. I got the database processes running, the build code, and everything else I can think of.
Versions of Python, at the moment:
CygWin
$ python --version
Python 2.7.14
Python 3.6.4
Windows
C:\Users\Owner\AppData\Local\Programs\Python\Python37>.\python.exe --version
Python 3.7.1
c:\Program Files\LibreOffice\program> python --version
Python 3.5.5
wait, found one more:
/cygdrive/c/emacs/emacs-26.1/bin
$ ./python.exe --version
Python 2.7.14
MingW64
[]@ MINGW64 /c/Program Files/Docker Toolbox
$ python --version
Python 3.7.1
LibreOffice
APSO python console [LibreOffice 6.1]
3.5.5 (default, Oct 30 2018, 00:49:44) [MSC v.1900 64 bit (AMD64)]
3.5.5 (default, Oct 30 2018, 00:49:44) [MSC v.1900 64 bit (AMD64)]
My next attempt will be to pull the python build chain into the Docker shell terminal, which I found out how to do when I noted the LibreOffice Python drop was also bereft of any tools.
