GDB：ModuleNotFoundError：没有名为“ _tkinter”的模块

Question

因此，我试图调试在Python ctypes gdb: break in shared library loaded by python中运行的C代码。 但是，每当我运行gdb时，都会出现以下错误：ModuleNotFoundError: No module named '_tkinter'。我知道有关此错误的问题很多：matplotlib error - no module named tkinter和ImportError: No module named 'Tkinter'。我尝试了以下方法：

sudo apt-get install python-tk

和

sudo apt-get install python3-tk

并且从Ubuntu命令行执行brandon@DESKTOP-V5LTF5T:~$ python3 MainApp.py时，它工作得很好。 但是从gdb执行时它不起作用： 为什么它可以在终端上运行但不能在gdb上运行？

您已经安装了tkinter用于python3安装，但是您正在从GDB运行python3-dbg。幸运的是，解决方案很简单：为调试解释器（python3-tk-dbg）安装tkinter：

>>> import tkinter

    import _tkinter # If this fails your Python may not be configured for Tk
ModuleNotFoundError: No module named '_tkinter'
