probably not mypy-tools related but can't fix it:

$ python3.6 /usr/local/bin/mypy_server.py

add PYTHONPATH

$ export PYTHONPATH=/usr/local/lib/python3.6/dist-packages/

different problem

Ah, the first error is because Python 3 doesn't have BaseHTTPServer any more. mypy_server.py doesn't quite support Python 3 yet. Not sure about the second error, but from some brief googling it looks like it might be caused by the fact you set your PYTHONPATH manually.

thx... it helped a bit... looks like python3 type hinting isn't supported

I think what's happening here is that the ast module in Python 2.7 doesn't know how to parse Python 3 code. Python 3 support for mypy_server.py (both for running and for parsing) are on the roadmap! The other tools in the package should support Python 3 however.

nice!
