调研方向

使用“Debug Python File in WASM”复现 src/declare.py 和 src/consume.py 的失败,并将其与“Run Python File in WASM”进行比较。首先跟踪 workspace 子目录的调试器入口点以及报告的 ModuleNotFoundError;当调试在 Debug Console 中输出“success”且没有 import 或 descriptor 错误时,即表示完成。

描述

Code Snippet

src/declare.py
def func():
    return "success"
src/consume.py
from declare import func

print(func())

Repro Steps

  1. Create files as above. Note that they are in the src subdirectory of the workspace.
  2. Open workspace root (parent of src) in https://insiders.vscode.dev/?vscode-coi=
  3. Open consume.py
  4. "Run Python File in WASM"
  5. Note that "success" is printed in the program output (Terminal pane)
  6. "Debug Python File in WASM"
  7. When debugger stops at top of file, press the "Continue" button in the debugging toolbar.

Expected behavior

Code runs successfully again and prints "success" in the program output (Debug Console pane)

Actual behavior

No "success" in program output. "Debug Console" shows the errors below. I think the "Bad file descriptor" may be a known issue, but note the ModuleNotFoundError.

If you move the two files from src to the workpace root, the code works as expected while debugging.

On desktop the code works as expected with the files in either location.

PDB debugger connected.
