pytest fails to resolve version when built but not installed

[jonassmedegaard]

For packaging Radicale for Debian, my build routines include running the testsuite after building the package, by running this command:

mkdir -p debian/python-module-stampdir
HOME="/build/radicale-2.1.10" py.test-3

..but at some point after 2.1.8 (probably commit 062e853) above fails like this:

_________________ ERROR collecting radicale/tests/test_auth.py _________________

I'm encountering the same exception with 3.0.3. When I clone the repository and try to run Radicale, I get:

[user@comms Radicale]$ python3 radicale.py --config ../config/g42_config

Installing Radicale via PIP is not an option, as I'm running 1.1.4 alongside while I attempt to upgrade.

Metadata for the Radicale package must be installed. This means that Radicale*.dist-info or Radicale*.egg-info must exist in Python's site-packages directory. The metadata is used to query our own version.
