Modern edk2 uses an environment variable PACKAGES_PATH to specify a ';' delimited list of directories to search for packages (in priority order). This is how e.g. edk2, edk2-platforms, edk2-non-osi would be collated as 'candidate locations' to pick up things referenced in the edk2 build files. Perhaps if it is unset, the tools are unhappy.
Try setting it to your workspace location and retrying the build, e.g. ``` set PACKAGES_PATH=%cd% :: or set PACKAGES_PATH=C:\edk\edk2 ``` I wouldn't have expected it to be mandatory or fail if undefined, but from the Python traceback it looks to be the case. Hope that helps!
