Notes on how to develop guizero (on Windows).
python.exe -m pip install pip --upgrade
Install / upgrade pre-requisites:
pip install mkdocs wheel twine virtualenv pytest pillow --upgrade
Create a virtual environment (not essential, but a good idea!):
virtualenv guizero-[versionno] cd guizero-[versionno]
Activate your virtual environment:
Checkout and install guizero for development:
git clone https://github.com/lawsie/guizero cd guizero git checkout dev python setup.py develop
When you have finished your development, deactivate your virtual environment:
To run the automated tests:
cd guizero\test pytest -v
If running the tests inside a virtual environment you will need to install pytest in that virtual enviroment.
pip install pytest
Note - tkinter can error when running the tests usually when the interpreter doesn't start properly, it doesnt seem to like being initialised and destroyed hundreds of times, I suspect a file locking issue as you dont see the problem on Linux. So sometimes you might get a test fail with an error like
This probably means that tk wasn't installed properly.. Just re-run the last failed errors!
pytest --lf -v
Test documents by serving up MkDocs:
cd guizero\docs-src mkdocs serve
