Problems with SITL

So I’ve been trying for hours to get this simulator working. Not sure if it’s just very terrible instructions or I’m missing something.
I’m on windows 10 and with Cygwin I get:
$ ../Tools/autotest/ -v ArduPlane --console --osdmsp SIM_VEHICLE: Start SIM_VEHICLE: Killing tasks
So nothing. Not even an error message.
If I use WSL, I get much further:
$ python ../Tools/autotest/ -v ArduPlane --console --osdmsp SIM_VEHICLE: Start SIM_VEHICLE: Killing tasks SIM_VEHICLE: Starting up at SITL location SIM_VEHICLE: WAF build SIM_VEHICLE: Configure waf SIM_VEHICLE: "/mnt/c/Users/Corrupt/ardupilot/modules/waf/waf-light" "configure" "--board" "sitl" "--osd" Setting top to : /mnt/c/Users/Corrupt/ardupilot Setting out to : /mnt/c/Users/Corrupt/ardupilot/build Autoconfiguration : enabled Setting board to : sitl Using toolchain : native Checking for 'g++' (C++ compiler) : /usr/bin/g++ Checking for 'gcc' (C compiler) : /usr/bin/gcc Checking for c flags '-MMD' : yes Checking for cxx flags '-MMD' : yes CXX Compiler : g++ 7.5.0 Checking for need to link with librt : not necessary Checking for feenableexcept : yes Checking for HAVE_CMATH_ISFINITE : yes Checking for HAVE_CMATH_ISINF : yes Checking for HAVE_CMATH_ISNAN : yes Checking for NEED_CMATH_ISFINITE_STD_NAMESPACE : yes Checking for NEED_CMATH_ISINF_STD_NAMESPACE : yes Checking for NEED_CMATH_ISNAN_STD_NAMESPACE : yes Checking for header endian.h : yes Checking for header byteswap.h : yes Checking for HAVE_MEMRCHR : yes Checking for program 'python' : /usr/bin/python Checking for python version >= 2.7.0 : 3.6.9 Checking for program 'python' : /usr/bin/python Checking for python version >= 2.7.0 : 3.6.9 Source is git repository : yes Update submodules : yes Checking for program 'git' : /usr/bin/git Checking for program 'size' : /usr/bin/size Benchmarks : disabled Unit tests : enabled Scripting : enabled Scripting runtime checks : enabled Debug build : disabled Coverage build : disabled Checking for program 'rsync' : /usr/bin/rsync 'configure' finished successfully (4.800s) SIM_VEHICLE: Building SIM_VEHICLE: "/mnt/c/Users/Corrupt/ardupilot/modules/waf/waf-light" "build" "--target" "bin/arduplane" Waf: Entering directory /mnt/c/Users/Corrupt/ardupilot/build/sitl’

ModuleNotFoundError: No module named ‘uavcan’`

But if I “pip install uavcan” I get namespace errors.
Before you suggest that I’m missing dependencies, I have already done:
git submodule update --init
Any ideas?

The command is
git submodule update --init --recursive

Recursive is important as it updates all submodules like uavcan
