Hi Michael,

do you know that python3.7 is also available in Cygwin ?
All versions availabe are:

$ ls  /usr/bin/python3* | grep -v config
/usr/bin/python3
/usr/bin/python3.6
/usr/bin/python3.6m.exe
/usr/bin/python3.7
/usr/bin/python3.7m.exe
/usr/bin/python3.8.exe


Where have you installed the node-gyp v5.1.0 and how ?

Regards
Marco
