As you see, the version on the sublime is Python 2.7 we need to use Python 3. Then we can set the Sublime Text to use Python3 instead of Python2. Here?s the step:

First: Check where is your Python3 path using this command

UNIX STYLE

$ which python3/usr/local/bin/python3

WINDOWS STYLE

C:Users<users>pyPython 3.7.1 (v3.7.1:260ec2c36a, Oct 20 2018, 14:05:16) [MSC v.1915 32 bit (Intel)] on win32Type “help”, “copyright”, “credits” or “license” for more information.>>> import os>>> import sys>>> os.path.dirname(sys.executable)’C:\Users\<user>\AppData\Local\Programs\Python\Python37-32′

Second: Add new build system on your Sublime

Tools -> Build System -> New Build System and make sure that the new build system has this following command

UNIX STYLE

{ “cmd”: [“/usr/local/bin/python3”, “-u”, “$file”], “file_regex”: “^[ ]File “(…?)”, line ([0-9]*)”, “selector”: “source.python”}

WINDOWS STYLE

{ “cmd”:[“C:/Users/<user>/AppData/Local/Programs/Python/Python37-32/python.exe”, “-u”, “$file”], “file_regex”: “^[ ]File “(…?)”, line ([0-9]*)”, “selector”: “source.python”}

and save this file as newPython3.sublime-build

Third: Select your new system build newPython3 and re-run the checkversion.py and now it should be using Python 3
