Python 脚本在 IDLE 中工作，但不能作为 .desktop 图标

Question

我正在尝试在 LX 桌面环境中单击图标 (.desktop) 时运行 python3 脚本。它以前工作过，但现在由于某种原因它没有打开，但仍在 IDLE3 中工作。因此，我在终端中输入“python3 oldtext.py”并收到以下错误：

Traceback (most recent call last):
  File "<frozen importlib._bootstrap>", line 2218, in _find_and_load_unlocked
AttributeError: 'module' object has no attribute '__path__'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "oldtext.py", line 3, in <module>
    from tkinter import *
  File "/home/pi/Desktop/tkinter.py", line 13, in <module>
    from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg
  File "/usr/lib/python3/dist-packages/matplotlib/backends/backend_tkagg.py", line 7, in <module>
    from six.moves import tkinter_filedialog as FileDialog
  File "/usr/lib/python3/dist-packages/six.py", line 89, in __get__
result = self._resolve()
  File "/usr/lib/python3/dist-packages/six.py", line 108, in _resolve
return _import_module(self.mod)
  File "/usr/lib/python3/dist-packages/six.py", line 79, in _import_module
__import__(name)
ImportError: No module named 'tkinter.filedialog'; 'tkinter' is not a package

但是当我尝试安装它时它（tkinter）已经安装了......

因为它说导入错误，这是我的导入：

#/usr/bin/env python3
#import necessary packages
from tkinter import *
try:
    import Tkinter as tk
except ImportError:
    import tkinter as tk
from PIL import ImageTk, Image
import time
import io
import os
import serial
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg
from matplotlib.figure import Figure
from matplotlib import pyplot as plt
import matplotlib.animation as animation
import numpy as np
import sys
import random

另外，这是 .desktop 文件。（我确实使脚本可执行）

[Desktop Entry]
Name=GUI DESKTOP
Exec=/home/pi/Desktop/oldtext.py
Icon=/usr/share/pixmaps/idle.xpm
Terminal=false
Type=Application
Categories=Application;Development;
StartupNotify=true

这里发生了什么？我假设这些错误是导致文件在单击图标时无法打开的原因。有人知道吗？

Answer 1

请注意，在您的错误中，它说：

  File "oldtext.py", line 3, in <module>
    from tkinter import *
  File "/home/pi/Desktop/tkinter.py", line 13, in <module>
    from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg

第二部分File "/home/pi/Desktop/tkinter.py"是重要的部分。它表明tkinter 模块已被另一个文件覆盖。而且，该文件的第 13 行是from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg，顺便说一下，这也是您粘贴在问题中的代码的第 13 行。我的猜测是你的文件被命名为tkinter.py，你需要重命名它才能让你的脚本工作。
