Venv installation failure

[Datise]

Hi I was attempting to install the tool using venv but ran into this:

➜  aiven-db-migrate git:(master) ✗ python3 -m venv venv
➜  aiven-db-migrate git:(master) ✗ . venv/bin/activate
(venv) ➜  aiven-db-migrate git:(master) ✗ pip install .

Apologies if I'm missing something, I don't really have python experience.

@Datise Thanks for reporting this. Can you try to run the following commands?

$ python3 -m venv venv
$ . venv/bin/activate
$ ## Run make to automatically generate the version info from git-tag
$ make
$ pip install .

NOTE: In case the process fails at psycopg2 installation stage, please also run pip install psycopg2-binary==2.8.6

[Datise]

Thanks for the help @ansrivas . I have run into installing psycopg2 and the suggestion doesn't resolve it. I'll did into it when I have time next week.

The problem is still current.

setup.py tries to import aiven_db_migrate/migrate/version.pythat doesn't exist in the repository.

Make need to be run to generate it, maybe it would be interesting to add a warning when running setup.py with this file missing ?
