Executable Made With Pyinstaller Experiences "fatal Python Error: Initfsencoding"

I am able to run my python (python 3.7) program on my pc from sublime text. The program uses tkinter and sqlite3. Does pyinstaller not support them? The error I'm getting when runn

Solution 1:

You are using python 3.7. As far as I have tested , modules like pyinstaller don't seem to be working in this version. Try uninstalling your python (don't forget to backup your files before), and installing python 3.6.3 or any other python 3 version except python 3.7. Same happened with me and I did this. It worked.
