Compiling a .py file with tkinter via cx_Freeze: what's wrong?

Question

Python

Made a program with tkinter. Tried to use cx_freeze for compilation. setup.exe-

import sys
from cx_Freeze import setup, Executable

build_exe_options = {"packages": ["os"], "excludes": ["tkinter"]}

base = None
if sys.platform == "win32":  
    base = "Win32GUI"

setup(name = "English Teacher",
    version = "1.0",
    description = "My application!",
    options = {"build_exe": build_exe_options},
    executables = [Executable("main.pyw", base = base)])

When I run the resulting exe, I get: "ModuleNotFoundError: no module named tkinter".
What should I try to do to fix the error?
