No, I'm only mounting the project / source files. The Docker build step creates a virtualenv for use inside the image, which is in a location different from the synced directory. I'm not syncing site-packages as I'm not installing the requirements on my Mac (and in particular the "downloadable" requirements). I'm only installing them inside the Docker image at Docker build time (and it's not clear to me whether packages pip-installed on my Mac would even be compatible with a different OS on the Docker image). It would be nice if pip-installing a project directory in editable mode didn't require writing to the project directory. Is there a fundamental reason it needs to?
