I don't think this message is due to Python versions. What OS are you working on, and how did you install Python?
I ran into the same error message on Windows 10 and using the Windows Store version of Python. This doesn't seem to work. My theory is that the build script looks for python.exe
in AppData\Local\Microsoft\WindowsApps
and there is only a link there, not a regular file.
Installing the 3.8.1 "proper release" from the Python site worked for me.
@johanster This is Debian 11 (bullseye/testing) and my python installation is straight from the Debian repos:
$ apt-cache policy python3
python3:
Installed: 3.7.5-3
Candidate: 3.7.5-3
Version table:
3.8.0-3 1

The issue seems to be that the python
binary is invoked, even though it should be python3
on most, if not all, Linux distributions.
I think it makes sense to search and invoke python3
explicitly. But I'm not so familiar with Windows; it would be nice to get @rukai's opinion here given that he did the windows setup steps initially.
Same issue as nbraud here, though I'm on Ubuntu 20.04. Installing python-is-python3
resolve the issue for me.
I can't use this library at all because of the Python requirement -- really wish people would eliminate their dependencies on fluff like that.
https://github.com/google/shaderc-rs/commit/21bb994197b536acabd1ddfd3ca82f27d1150645 was landed a while ago to try to search Python3 first. Not sure that's sufficient to address the issue. If not, please open new issues.
The build instructions only mentions Python 3.x, yet attempting to build without Python 2.x installed results in a build failure:
Given that Python2 reached its end-of-life on January 1st, and that many distributions (including Debian) are removing it from their future releases, I would strongly recommend getting rid of the dependency.
