SyntaxError: invalid syntax running pyt on MacOS Sierra

[greg5678]

I'm trying to run pyt on MacOS Sierra and it seemed to install properly with sudo pip3 install python-taint. When I ran pyt against a python file it printed SyntaxError: invalid syntax. Looking at the errors printed I believe it has to do with the python version I have installed.

python --version
Python 2.7.15

python3 --version
Python 3.7.0

Traceback (most recent call last):

3.6

[greg5678]

How do I set the python version to 3.6? BTW does pty only work with python 2.7 code?

[KevinHock]

(Apologies for the brief response before, was on my phone.)

PyT only runs on Python 3 code and runs as Python 3. Here is how you can set up a virtualenv for Python3.6, it should work on 3.7 as well.

Cheers,
