Python Flask Restful SQLite, based on the Python Flask Framework, is mainly focusing on demonstrating the implementation of an application using a Restful Api to access an SQL database (SQLite). It is also demonstrating the use of Ionic Stencil Web components into Jinja2 templates.

You can make sure that pip is up-to-date by running:
pip install --upgrade pip
Then check for virtualenv installed on Python
python -m virtualenv --version
If not
py -m pip install --user virtualenv
Then execute setenv to set-up the environment and the application requirements.
setenvor
./setenvA virtual environment appenv should have been created.
activateenvor
./activateenvThe virtualenv appenv is now activated
An (appenv) prompt should have been added to your working path.
You should get the response: "workingpath"/appenv/bin/python
Then check that Flask has been installed in the ``àppenv```environment
