wiliot-testers 5.13.3

A library for interacting with Wiliot's Testers app

PyWiliot: wiliot-testers

wiliot-testers is a python library for accessing Wiliot's Testers scripts

Public Library

MAC Installation

Getting around SSL issue on Mac with Python 3.7 and later versions

Python version 3.7 on Mac OS has stopped using the OS's version of SSL and started using Python's implementation instead. As a result, the CA certificates included in the OS are no longer usable. To avoid getting SSL related errors from the code when running under this setup you need to execute Install Certificates.command Python script. Typically you will find it under

/Applications/Python\ 3.7/Install\ Certificates.command

Python 3 on Mac

The default Python version on mac is 2.x. Since Wiliot package requires Python 3.x you should download Python3 (e.g. Python3.7) and make python 3 your default. There are many ways how to do it such as add python3 to your PATH (one possible solution https://www.educative.io/edpresso/how-to-add-python-to-the-path-variable-in-mac)

Git is not working after Mac update
