Actual Results

Expected Results

No error.

Additional info

This error is showing up when executing “pio update”, so I think it is a pio core problem and commit issue here.

This is not an issue. PlatformIO Core 5.2.3 depends on the previous version of SCons where the 5.2.4 release introduces support for SCons 4.3.

But it is an issue. PlatformIO Core 5.2.3 wants to install the incompatible Scons 4.3 and not the previous SCons release that is compatible. Therefore anyone installing fresh or (in my case) automatic update of platform.io in VSCode are gonna get Platform.IO 5.2.3 with a broken SCons.

The automatic updates is how I ended up in my predicament and eventually found this ticket. Sure the force update to the dev version fixed the problem but it isn’t good that platform.io can “break” itself in this fashion.

So…platform.io “stable” is more-or-less broken is what you are tell us? I can’t build anything marlin as platformio/tools-scon won’t install because it is incompatible with the “stable” version of platform.io.

C:\users\credomane\.platformio\python3\python.exe: can't open file 'C:\users\credomane\.platformio\packages\tool-scons\scons.py': [Errno 2] No such file or directory

Platform.io should really install the newest compatible version of packages rather than just flat out refusing to install at all. I don’t mine updating to the dev version to resolve this but it was a frustrating weekend of finding years old issues that don’t apply anymore. Then today I find this closed github issue.
