Resources

• cygwin on Windows 10
• python 3 (installed via Cygwin installer)

Features Used

• python 3
• SQLAlchemy
• Flask with JWT Authentication
• SQLite

Installing Cygwin and Python3

• Re-run the cygwin install
• NOTE: if you haven't run Cygwin in a while, it upgrades lots/all packages
• Select mirror
• in the Package selector, select "Category" (much easier to read)
• Type "python3", and select the interpreter
• Type "pip3", and select the pip installer

Installation

Prep

• Within Cygwin
• pip3 install virtualenv

Creating virtualenv by hand (needs to be done once per installation)

• virtualenv venv --python=python3
• python -V (will likely show you version 2)
• source venv/bin/activate
• python venv/bin/pip install -r requirements.txt

Copy of requirements.txt

aniso8601==2.0.0
click==6.7
Flask==0.12.2
Flask-JWT==0.3.2
Flask-RESTful==0.3.6
Flask-SQLAlchemy==2.3.2
itsdangerous==0.24
Jinja2==2.10
MarkupSafe==1.0
PyJWT==1.4.2
pytz==2017.3
six==1.11.0
SQLAlchemy==1.2.0
Werkzeug==0.14.1

installing the (slightly) harder way: python venv/bin/pip install Flask-RESTful Flask-JWT Flask-SQLAlchemy (also installs Flask)

Starting the back-end server

• source venv/bin/activate
• python app.py

Running it

• (within Cygwin) python3 app.py
• Should say:

* Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)

Other commands and notes

• python venv/bin/pip freeze NOTE: you no longer need pip3 NOTE: turns out unix scripts cannot have a space in the shebang path, so "pip install Flask-RESTful" will fail
