ipython import error

[lennart-scale]

Hi, I have nbqa version 1.85 installed and would like to use it as a pre-commit hook. I am using python 3.8 and manually installed ipython 8.12.0. this is my .pre-commit-config.yaml file

repos:
  - repo: https://github.com/psf/black
    rev: 22.12.0
    hooks:
      - id: black
        name: "python:black"
        entry: black --config .black.toml
        additional_dependencies: ['click<=8.0.4'] 
  - repo: https://github.com/PyCQA/flake8
    rev: 6.0.0
    hooks:
      - id: flake8
        name: "python:flake8"
  - repo: https://github.com/pycqa/isort
    rev: 5.12.0
    hooks:
      - id: isort
        args: ["--settings-path", ".isort.cfg"]
        name: "python:isort"
  - repo: https://github.com/nbQA-dev/nbQA
    rev: 1.8.5
    hooks:
      - id: nbqa-black
        name: "ipynb:black"
        entry: black --config .black.toml
        additional_dependencies: [black==22.12.0]
      - id: nbqa-flake8
        name: "ipynb:flake8"
        additional_dependencies: [flake8==6.0.0]
      - id: nbqa-isort
        name: "ipynb:isort"
        args: ["--settings-path", ".isort.cfg"]
        additional_dependencies: [isort==5.12.0]

When running the hook on a specific ipynb file, pre-commit run --file X.ipynb, I keep getting the following error trace:

- hook id: nbqa-black
- exit code: 1

Python 3.3 and 3.4 were supported up to IPython 6.x.
Python 3.5 was supported with IPython 7.0 to 7.9.
Python 3.6 was supported with IPython up to 7.16.
Python 3.7 was still supported with the 7.x branch.

See IPython `README.rst` file for more information:

    https://github.com/ipython/ipython/blob/main/README.rst

And the same error appears for ipynb:flake8, ipynb:isort. The error message indicates that the ipython version is not compatible with python 3.8. However, the ipython I installed, 8.12.0, is explicitly compatbile. Does something else happen under the hood or does nbqa require a specific ipython/min python version?

thanks for the report

no idea, sorry, looks like an issue with your python environment

closing then as this doesn't seem actionable, but will reopen if further details are provided
