Too high Pydantic version

[thevops]

My virtual environment, after pip install grafana_dashboard:

> pip freeze
annotated-types==0.5.0
click==8.1.4
grafana-dashboard==0.1.1
markdown-it-py==3.0.0
mdurl==0.1.2
pydantic==2.0.2
pydantic_core==2.1.2
Pygments==2.15.1
rich==13.4.2
typer==0.9.0
typing_extensions==4.7.1

Error:

Temporary solution (downgrade pydantic):

pip install pydantic==1.10.2

I think that something has changed in pydantic library.

By the way, nice tool :) thanks

You are welcome! Oops, pydantic v2 seems incompatible with v1. Feel free to PR to change it (should be a good first issue), e.g. fixing version to 1.x

Sorry to revive this old issue, but still the same problem occur when I create a virtualenv with pyenv, using python 3.10 like this:

pyenv local 3.10
pyenv virtualenv 3.10 grafanalib
pyenv activate grafanalib
pip install grafana_dashboard
...
grafana_dashboard json-to-python --json-path ~/workspace/ionos/helm-charts/charts/base-cluster-service/dashboards/container-image-versions-overview.json --python-path .

Seems like the upper version limit for Pydantic defined in #3 is not taking effect:

pip list
Package           Version
----------------- -------
annotated-types   0.7.0
click             8.1.7
grafana-dashboard 0.1.1
markdown-it-py    3.0.0
mdurl             0.1.2
pip               24.0
pydantic          2.7.4
pydantic_core     2.18.4
Pygments          2.18.0
rich              13.7.1
setuptools        70.0.0
shellingham       1.5.4
typer             0.12.3
typing_extensions 4.12.2
wheel             0.43.0

If I downgrade to the Pydantic version as defined in setup.py with pip install 'pydantic>=1.10.2,<2', I get the dashboard defined in Python code.

Hmm, what about using the code on master branch, does it work for you?
