Describe the bug

I got this error after trying to install a package using the Marimo tool for installing packages. Related but not the same as:

Environment

  },
  "Dependencies": {

}

Code to reproduce

cd /tmp
mkdir marimo-venv
cd marimo-venv
python -m venv venv
source venv/bin/activate
pip install marimo
marimo new

Then:

import llm

And ask it to install that package.

AttributeError: module 'pkgutil' has no attribute 'ImpImporter'. Did you mean: 'zipimporter'?
akshayka commented 4 weeks ago

I googled AttributeError: module 'pkgutil' has no attribute 'ImpImporter'. Did you mean: 'zipimporter'? and found a lot of hits.

So it seems like the version of pip that is being used is incompatible with Python 3.12.

Why that would happen, I am currently unsure.

I noticed you marimo env lists Python 3.12, but your venv appears to be using Python 3.10, which is perplexing but could explain the issue.

Is it at all possible that marimo is installed globally? Does which marimo return something inside the venv or outside it?

I'm definitely suffering from https://xkcd.com/1987/ - I've lost track of which Python environment and which Marimo installations I have lying around I'm afraid.

I think you're right, the root cause here is definitely that I somehow had a Python 3.12 running against a 3.10 virtual environment. No idea at all how that happened though!

Looking forward to the day when uv is totally feature complete and universally adopted and never have to think about virtual environments again 😅 One can dream ...!
