Hi all,
I’m testing Nix with MacOs. I’m using nix-shell with mach-nix to create a python env with wxPython and other python libs. It’s building correctly the env but when I try to run a code using wxpython I see this error:
This program needs access to the screen. Please run with a Framework
build of python, and only when you are logged in on the main display
of your Mac.
Is there a way to fix this problem?
I think this problem is because Python in Nix doesn’t the Framework part. Is there a way to have it in Nix?
What is your script/Os info?
on Linux
the minimal example works:
nix-shell -p nixFlakes --run "nix run github:davhau/mach-nix#with.ipython.wxpython --show-trace "
import wx; a=wx.App(); wx.Frame(None, title="Hello World").Show(); a.MainLoop()
My OS is Mac OS X 10.13.6. If I run your python commands it shows this message:
This program needs access to the screen. Please run with a Framework
build of python, and only when you are logged in on the main display
of your Mac.
It’s because it needs a python compile with Framework enabled. I’m trying with this shell.nix where I’m overlaying python to enable framework:

It’s compiling python but it’s not compiling libxml2, maybe I need to change more things yet.
I did some progress, now it’s compiling much more things. Unfortunately, my Macbook is old (last Macbook white released), so it take a lot of time to compile the things.
