问ModuleNotFound (tkinter)，但我已经尝试了我发现的一切，但都没有用

EN

Linux，pop_os，vs代码，python3

import tkinter as tk
win = tk.Tk()
win.title("Hello World")
win.mainloop()

python main.py -> ModuleNotFoundError: No module named 'tkinter'

python3-tk和python-tk已经安装了apt

python --version (在vs代码终端) -> Python 3.9.9

pip3 install tk (在vs代码终端) -> Requirement already satisfied: tk in /var/data/python/lib/python3.9/site-packages (0.1.0)

pip3 install tkinter (在vs代码终端) -> ERROR: Could not find a version that satisfies the requirement tkinter (from versions: none) ERROR: No matching distribution found for tkinter
