尝试在 Jupyter 笔记本中运行“black”时找不到模块

Question

I've created a Jupyter notebook inside of a virtual environment.

These packages are installed:

black==22.12.0
jupyter~= 1.0.0
jupyter-black==0.3.3
jupyter-contrib-nbextensions~=0.5.1

In my notebook, there's a button with a little gavel to run black code formatting. However, when I click this, I get the error message:

localhost:8888 says 

[jupyter-black]
 Error:ModuleNotFoundError
No module named 'black'

I've made sure I'm using the kernel created inside this virtual environment.

Reading through the docs has not pointed out any obvious errors I'm making here. Any suggestions on getting black to run appropriately?

Answer 1

Run something like the answer here :

python -m ipykernel install --name=my-virtualenv-name
