Can't install wxPython

Newbie Help
#1

Hello :slight_smile:
It’s my first time using python and downloading wxPython. I’m using Python 3.8 and pip3. When I type pip3 install wxPython, I get a really long error and I can’t figure out how to fix it. Anything help would be much appreciated, thank you so much!

Hi Anusha, this pip install tries to build wxPython from the sources.
This is not the recommended way to get started.
What is your platform? Maybe binaries are available, but PyPi does only supply them for Windows and MacOS.

#3

Ah, i see x86_64-apple-darwin21.
For Python 3.7 PyPI does not have current binaries any more: wxPython · PyPI

Can you live with the older revision 4.1.1?
This is available: wxPython · PyPI

#4

I’m confused: You’re writing that you’re on Python 3.8, but your log shows 3.7.

If you have a 3.8, then do something like this:
python3.8 -mpip install wxpython
At least on other platforms the executable pip or pip3 often points to another binary than what you expect. Calling python with -mpip should solve this.

#5

Hey, I checked the version and it said 3.8.8 for python.
I tried running the code you wrote above, and I apologize for the long text here -

python3.8 -mpip install wxpython

Python 3.8.8
#6

I don’t have 3.8 on my MacOS VM, so I can’t reproduce why pip wants to use the source instead of a binary. My installation pre-dates the universal wheels for x86 and ARM.

Could you please try to purge the cache first with python3.8 -mpip cache purge

If that still fails, maybe download the .whl file from https://files.pythonhosted.org/packages/52/1e/d95b693c2f123b7bf5f816e4d0a390d5d3cdb88672bfb899b3d1bbb6887a/wxPython-4.2.1-cp38-cp38-macosx_11_0_universal2.whl

Then install it from that:
python3.8 -mpip install wxPython-4.2.1-cp38-cp38-macosx_11_0_universal2.whl
If that still fails, I don’t know a solution…

Alternatively, it seems you’re using Anaconda. That should have a package manager. I don’t remember the command line for this as I don’t like it…

#7

Thank you for your help thus far! I tried clearing the cache, then running the script. Did not work.
I tried downloading the .whl file, but it gave me an error -

> ERROR: wxPython-4.2.1-cp38-cp38-macosx_11_0_universal2.whl is not a supported wheel on this platform.

#8

OK, that might be the root cause. I don’t have experience with the universal wheels. Maybe Python 3.8 does not support it at all or your pip is too old.
You can upgrade pip using python3.8 -m pip install --upgrade pip

If that still fails, for the time being, you may try to use wxPython revision 4.1.1.
That seems to have a ‘classic’ wheel: wxPython · PyPI
You can install a specific version using ==:
python3.8 -mpip install wxPython==4.1.1
Good luck.
