Running pythontex in a virtual environment

[sehHeiden]

Type of JetBrains IDE (IntelliJ, PyCharm, etc.) and version

PyCharm

Operating System

Linux

TeXiFy IDEA version

0.9.9

What I did (steps to reproduce)

Added pythontex as external tool in before launch.

So my before lauch looks like:

1. run the old automatic created steps
2. run pythontex

Minimal example to reproduce the problem

\documentclass{article}
\usepackage{pythontex}

\begin{document}
\begin{pycode}
"""Show Graphs for Statistic of MaStR."""
print("Hallo")
\end{pycode}
\end{document}

Expected behavior

This behaviour works from the PyCharm terminal. Here the python version is: Python 3.12.6

1. pdflatex
2. pythontex
3. pdflatex

Actual behavior

Get the error below.
Altough I have a .venv that works, has the correct python version as in the .python-version file.
Looks for me, that not the correct python python is used?

(if applicable) The full stacktrace of the exception thrown

  pyenv: version `3.12.6' is not installed (set by /home/.../.python-version)

[sehHeiden]

I added an init.py file to the out folder and the folder of the latex files.

Not changing the error.

Do I have to activate the .venv for the external tools (not needed in the terminal).

I tried:

uv run pythontex

Not changing the error.

Thanks for the question, indeed in the current External LaTeX tool run configuration the command is hardcoded and will be run outside the virtual environment. Could you try with a regular external tool, and then activate the virtual environment there? For example, source .venv/Scripts/activate && pythontex main

(I think this functionality did not exist at the time I created the external tool run config, maybe it is obsolete now)

[sehHeiden]

What I tried is to write a bash script, that that sources the environment first and then executed pythontex.
That did work, but need to be handled slightly differently on win.

I just realised that just using a 'before launch' tool may not quite fix it, because you need to run LaTeX - pythontex - LaTeX. I think the best solution is to add environment variables to the External Tool run configuration, then you would be able to edit PATH so that pythontex will pick up the correct python executable.
Until then, I don't see an easier workaround than indeed such a bash script.
