Running script doesn't do anything while debugging in vscode? (Starts a python interpreter when I do this from an lldb terminal session.)

[holland11]

If I start lldb through my OS's terminal and then type script, I get:

(lldb) script
Python Interactive Interpreter. To exit, type 'quit()', 'exit()' or Ctrl-D.
>>> 

Whereas if I start a debugging session within vscode via codelldb and then type script in the debug console, nothing happens. No error is reported or anything. Normal lldb commands seem to work properly in this console.

I enabled verbose logging and this is the output that gets printed when I run script:

I spent quite a bit of time googling this and I came across one thread where it was mentioned to make sure you set the lldb.libpython attribute within your settings.json file, however as far as vscode is concerned, this attribute isn't valid. The posts where this attribute was mentioned are from 2020 so maybe it's no longer a valid setting?

I'm hoping to be able to start a python interpreter within the vscode debug console and I'd also like to be able to just have lldb execute an existing python script. I tried script /script_path/script.py but I was met with SyntaxError: invalid syntax. That one doesn't work in my terminal lldb either so I'd be curious to know how I can achieve this functionality as a side-question to this post.

Happy to provide anymore info to help sort this out.

Thank you.

Sorry, interactive Python REPL is not supported in VSCode debug console. You can execute one-liners though, e.g. script print(x). To execute a script, use command script import <path>.
