I'm running into trouble locating Python libraries in a polyglot document, i.e. one that contains both R and Python code chunks. This fails with Quarto 1.1.335 but works on another machine with Quarto 1.1.269 (both running Pop!OS 22.04). (No RStudio environment, running quarto from the command line)

Here's my .qmd file:

---
title: "polyglot"
---

```{python split}
import pandas as pd
```

```{r test}
print("hello world")
```

If I quarto render this I get

Quitting from lines 8-9 (test.qmd)
Error: ModuleNotFoundError: No module named 'pandas'
Execution halted

If I delete the R chunk rendering works: I get

Starting python3 kernel...Done ... Executing 'test.ipynb' ... Cell 1/1...Done

quarto check output:

[✓] Checking Quarto installation......OK
Version: 1.2.335
Path: /opt/quarto/bin

[✓] Checking basic markdown render....OK

[✓] Checking Python 3 installation....OK
Version: 3.10.6
Path: /usr/bin/python3
Jupyter: 5.2.0
Kernels: python3

[✓] Checking Jupyter engine render....OK

[✓] Checking R installation...........OK
Version: 4.3.0
Path: /usr/local/lib/R
LibPaths:
- /usr/local/lib/R/site-library
- /usr/local/lib/R/library
rmarkdown: 2.20

[✓] Checking Knitr engine render......OK

The other install (on which rendering works) is Jupyter 4.9.1 but otherwise the same (at least as far as quarto check is concerned)
