I use Spyder ide from Anaconda, I just play around with python and try to make the message encode/decode. I get many error from installing the library tkinter and base64. Eventually it runs but have to change to pip install tk/pybase64 instead. And after some trouble, there is new error that I completely don't know how to fix. Resources on the internet don't help me much.

ERROR: cannot import name 'messagebox' from 'tk'

CodePudding user response：

You don't need to install tkinter or base64 separately at all, they're both built-in. (If Tkinter support hasn't been built in to your Python installation, you will need to rebuild Python with Tkinter support, you can't just install it separately.)

• If you have indeed done pip install tk, then you will have installed this package that is unrelated to tkinter. You'll want to uninstall it.
• Similarly, you don't need pybase64 to do base64 operations. Best uninstall it too.
• Thirdly, make sure your script isn't called tk.py itself.
• Finally, as mentioned above, the module is tkinter, not tk. It's just common to do import tkinter as tk for brevity.
  • Also, using * imports is generally not a good idea; you'll find your namespace polluted with all sorts of symbols you won't need or know where they're from.

try to import tkinter, from tkinter import messagebox you can also do the same with the rest of the imports

from tkinter import * as tk
import pybase64
from tkinter import messagebox
