I believe the issue stems from this command run by node-gyp:

C:\Program Files\Anaconda3\python.EXE -c import sys; print "%s.%s.%s" % sys.version_info[:3];

I suspect the -c argument needs to be wrapped in quotes, but isn't.

A quick perusal of node-gyp issues suggest that python3 isn't supported, and that using 2.7 is recommended. python3 requires the print statement to be in parenthesis. Other issues suggest using Powershell vs. command prompt.

Unfortunately, I'm not well versed in Windows development intricacies, so I'm not able to help much.

I will close this issue as it is not strictly related to headless-gl, but to node-gyp. Please re-open if you think this is not the case, and also please post your eventual solution.
