What is the expected behaviour?

pip upgrade should not fail and should install with pre-build wheels without the need to install additional ms toolchains

Do you have any other information from investigating this?

No

Hi @Franky1. I see that you've reported this issue for the reedsolo package as well (tomerfiliba-org/reedsolomon#32). This is very weird and I think something is wrong with your Python. We are using Python 3.8.7 as the default one for ESP-IDF where this package is installed and used by many customers. I have no information beside yours that Visual C++ would be required. I don't have it neither and have it with 3.8.7.

Do you have some special distribution of Python? Could you please try one 3.8.x from python.org? 3.9.x is the newest one but lets keep trying to debug 3.8.x.

[Franky1]

I am usually using WinPython distributions for all of my windows machines:
https://winpython.github.io/

I suspect something is broken with this particular WinPython version.
I just tried it on another computer with 3.7.7, there pip install --upgrade esptool worked without errors.

[dobairoland]

Great! I'm happy that you've found a workaround which works for you.

I think we can close this because we don't handle Python selection at the Esptool level.

Still after switching from WinPython 3.8.6.0 to WinPython 3.8.8.0 on this machine, i had no success to install esptool respectively reedsolo.

Only after installing the latest Microsoft Visual C++ 14.2 Build Tools on this machine I was able to install esptool respectively reedsolo without any error messages.

I still wondered why a ready-made wheel is not taken instead.
It could be because for reedsolo currently only one wheel is provided for Python 3.7

https://pypi.org/project/reedsolo/#files

That's why my attempts under 3.8.x.x all failed?
