Incompatible dependencies

[Samurai336]

There is a dependency conflict when trying to install grapmps-webapi dependencies.

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
flake8 5.0.4 requires importlib-metadata<4.3,>=1.1.0; python_version < "3.8", but you have importlib-metadata 4.13.0 which is incompatible.

Did the following to get this issue on Linux Mint:

Once repository is cloned

1. In grapmps-webapi project root setup a new virtual environment set to python 3.7 and activate environment. I used pyenv with pyenv-virtualenv plugin

2. Edit your virtual environments pyvenv.cfg file (for me it was in ~/.pyenv/versions//pyvenv.cfg) to set include-system-site-packages to True and save.

3. Install dev dependencies pip install -r requirements-dev.txt

4. Install gramps-webapi and dependencies pip3 install -e .

This should create the conflict error listed above. Not using --user on the editable dependency install because it in the virtual environment it would create a lack of sys.path precedence to gramps-webapi (see pypa/pip#573)

python3.8 does not have this dependency conflict so does the project need to up its python dependency requirement?

Can you try updating flake8? It's just a development dependency without version pin...

it installs but I get an error warning me

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
gramps-webapi 1.1.8 requires importlib-metadata==4.13.0, but you have importlib-metadata 4.2.0 which is incompatible.

Ok. The version pin was added because of this issue python/importlib_metadata#411 which caused builds to fail on 3.7. Can you please try what happens when you remove the version pin in Web API?

[Samurai336]

I don't get a dependency conflict when I remove the pin from the setup.py. pip says it now has 4.2.0 of importlib-metadata installed

[DavidMStraub]

Cool, perhaps the bug has been fixed. Do you want to submit a PR?

[Samurai336]

I am still having precommit issues. Trying to resolve that is how I ran into this. :)

[Samurai336]

You'll have to check me because I just did --no-verify

Fixed by #422.
