Sorry, I forget how I installed the old python 3.7.5, but I installed the new python 3.8.5 using the downloaded installer from Python.org. Besides, I checked the "Tcl" under the path: "/System/Library/Tcl", its version still is 8.5. I think my code used the library here, and this is the reason why the warning showed.
