I’m trying to build Microsoft’s thermal soaring implementation (https://github.com/microsoft/Frigatebird) for SITL simulations on Ardupilot, and I’m following the build instructions from the Github repository’s BUILD.md
However, I’m getting this error when running “./waf distclean” in Cygwin on a Windows 10 machine with Python 3.7 installed:
$ ./waf distclean
Traceback (most recent call last):
File "/home/User/Frigatebird/modules/waf/waflib/Node.py", line 590, in ant_iter
raise StopIteration
StopIteration
The above exception was the direct cause of the following exception:

Is this an issue with one of the Python modules?
