I'm new to VS Code and Python. When I tried to use interactive window I failed to install IPykernel. I am using Mac system and have already installed Jupyter and Python in VS Code. I am using conda environment and looked for some solutions but they didn't work.

When I tried to run interactive window it showed:

Running cells with 'Python 3.13.3' requires the ipykernel package.
Create a Python Environment with the required packages.
Or install 'ipykernel' using the command: '/usr/local/bin/python3 -m pip install ipykernel -U --user --force-reinstall'

I then tried to install it but it seems that it was already installed:

python % pip install ipython ipykernel

I tried to run interactive window again but still failed

Running cells with 'Python 3.13.3' requires the ipykernel package.
Install 'ipykernel' into the Python environment. 
Command: '/usr/local/bin/python3 -m pip install ipykernel -U --user --force-reinstall'

  • What happened exactly when you tried /usr/local/bin/python3 -m pip install ipykernel -U --user --force-reinstall? Please show us that output instead of pip install ipython ipykernel (since that command is more ambiguous, i.e. it depends on your system, how you set up pip, where you're running it, etc).

  • Please don't post pictures of text. Instead, copy the text itself (as you did with other bits), edit it into your post, and use the formatting tools like code formatting. If you had gotten a message that your post was too much code and not enough other text, then I think you can filter out any lines that start with "downloading" or "using cached" and still preserve all the important details.

  • When you created a new environment (env for short), did you switch to that env? I don't think VSCode does it for you. Commented Jun 13 at 15:12
  • BTW, you have some errant text in the command: ' , and m pip install ipython ipykernel Commented Jun 13 at 15:14
  • BTW, welcome to Stack Overflow! Check out the tour, and see How to Ask if you want tips, like how to write a good title. A better title might be something like "Why can't Jupyter in VS Code find IPykernel even though I've installed it three different ways?" If you're not sure, I can suggest something else once you post the missing details. Commented Jun 13 at 15:18

It sounds like you didn't select the conda environment (env for short) in VSC, otherwise it would suggest using conda instead of pip, and wouldn't suggest creating a new env.

For help, see Select and activate an environment in the VSCode Python docs.
