Update project in venv on each build

[lordmauve]

Description

When running thx test I noticed had a test failure. When I fixed the test failure in my project source, thx test still shows the failure.

This is because the project itself is installed into the virtualenv with pip install -U . and pip only replaces it when the version number increases. I'm using flit_scm so version numbers will increase with commits, but uncommitted staged/unstaged changes are not causing a reinstall.

This could be fixed by passing --force-reinstall or --editable to pip install.

Details

• OS: Linux
• Python version: 3.10 to 3.12
• thx version: 0.6.0
• Can you repro on main? Haven't tried but analysis says yes
• Can you repro in a clean virtualenv? Haven't tried but analysis says yes
