GDB：ModuleNotFoundError：沒有名為“_tkinter”的模塊

Question

So I'm trying to debug my C code ran in Python ctypes: gdb: break in shared library loaded by python . 但是，每當我運行 gdb 時，我都會收到以下錯誤： ModuleNotFoundError: No module named '_tkinter' 。 我知道關於這個錯誤有很多問題： matplotlib error - no module named tkinter和ImportError: No module named 'Tkinter' 。 我嘗試了以下方法：

sudo apt-get install python-tk

和

sudo apt-get install python3-tk

從 Ubuntu 命令行執行時它工作得非常好： brandon@DESKTOP-V5LTF5T:~$ python3 MainApp.py但從 gdb 執行時它不起作用： 為什么它可以在終端上工作，而不是 gdb？

Answer 1

您已經為 python3 安裝安裝了tkinter ，但是您正在從 GDB 運行python3-dbg 。 幸運的是，解決方案很簡單：為調試解釋器（ python3-tk-dbg ）安裝 tkinter：

➜  ~ python3-dbg
Python 3.6.9 (default, Apr 18 2020, 01:56:04) 
[GCC 8.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import tkinter
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python3.6/tkinter/__init__.py", line 36, in <module>
    import _tkinter # If this fails your Python may not be configured for Tk
ModuleNotFoundError: No module named '_tkinter'

我面臨同樣的錯誤。升級你的 Python 版本。我希望這對你有用
