不同版本的python导入的不同tkinter版本

Question

我在macOS上安装了Tkinter version 8.6。 当我运行python3.7（键入python时的默认python版本）时，将成功加载tkinter 8.6版：

python3.7
Python 3.7.4 (default, Aug 13 2019, 15:17:50)
[Clang 4.0.1 (tags/RELEASE_401/final)] :: Anaconda, Inc. on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import tkinter as tk
>>> print(tk.Tcl().eval('info patchlevel'))
8.6.10

在python3.8上不是：

python3.8
Python 3.8.6 (default, Oct  8 2020, 14:06:32)
[Clang 12.0.0 (clang-1200.0.32.2)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import tkinter as tk
>>> print(tk.Tcl().eval('info patchlevel'))
8.5.9

我也需要8.6.10加载python3.8
