There is no python3 exe file  that is why it fails   Try      py   instead   py is just a launcher for python exe  If you have more than one python versions installed on your machine  2 x  3 x  you can specify what version of python to launch by     py -2 or    py -3

In my case I have a git hook on commit  specified by admin  So it was not very convenient for me to change the script  with python3 calls    And the simplest workaround was just to copy python exe to python3 exe   Now I could launch both python and python3

You can also try this  Go to the path where Python is installed in your system  For me it was something like C  Users  Local Settings Application Data Programs Python Python37 In this folder  you ll find a python executable  Just create a duplicate and rename it to python3  Works every time

Yes  I think for Windows users you need to change all the python3 calls to python to solve your original error  This change will run the Python version set in your current environment  If you need to keep this call as it is  aka python3  because you are working in cross-platform or for any other reason  then a work around is to create a soft link  To create it  go to the folder that contains the Python executable and create the link  For example  this worked in my case in Windows 10 using mklink   cd C  Python3 mklink python3 exe python exe   Use a  soft  symbolic link in Linux   cd  usr bin python3 ln -s python exe python3 exe
