Hi,
I work with M/EEG data and would like to check out some things in Julia. To load data etc I would need PyMNE:
> **[GitHub - beacon-biosignals/PyMNE.jl: Julia interface to MNE-Python via PythonCall](https://github.com/beacon-biosignals/PyMNE.jl)**
>
> Julia interface to MNE-Python via PythonCall
“using PyMNE“ seems to install some Python packages however crashes Julia at some point. See message below. I would appreciate any pointers.
Thanks & best,
Nathan

Thanks. So I did:

That took a little longer.
However then I get the crash again:

Can you also show `pkg> status` ?

Hmmm, I’m unable to replicate in a clean environment. Can you try restarting Julia (in your `mnetest` environment – thanks for using a small environment!) and then re-running `using PyMNE`? I’m wondering if you were still loading the released version because of the way package updates work on already loaded packages.

It behaves differently now, but in the end still crashed. See below.
Anyhow, thanks a lot. I was just messing around. When doing analysis with MNE I would likely still stick with Python environment. But interested in doing more in Julia in future.

A more knowledgable colleague had a look today. Turns out that my XCode command line tools were quite outdated. Installing the newest version (from [Xcode 15 - Apple Developer](https://developer.apple.com/xcode/)) solved the problem.
Now PyMNE installs fine.
Thanks for taking your time!
