如何调试由 pip 安装的工具？

Question

I have a tool installed by the command pip install.

However, I would like to use a debugger to go through its execution flow.

I know for debugging what usually happens is attach pdb in command line. like python3 -m pdb [some args]

But the tool is working like this tool [some args]

How can attach a debugger to this?

Answer 1

On Linux in console/terminal you can use

which tool

to get /full/path/to/tool

and then you can run

python3 -m pdb /full/path/to/tool [some args]

You can also use /full/path/to/tool to open it in text editor and see source code, and add some code for debuging.

On Windows should be similar function to find full path to tool and then you can do the same.

If you can import tool in Python then you can also use print( tool.__file__ ) to get /full/path/to/tool
