Set cwd in VS CODE

Question

VS CODE 1.52.1 Python 3.7.9

Path structure

• MyWorkspace
  • Folder Main
    • MyWorkspace.code-workspace
    • MainModule.py
  • Folder A
    • SubModule_A.py
  • Folder B
    • SubModule_B.py

---

In the past, I could import "MainModule.py" in all of sub-modules in any directory easily like below.

import MainModule

But after I reinstall VS Code, they are unable to find modules in different paths. I've found some solutions importing modules with absolute paths, but there are hundreds sub-modules already making hard to modify them all.

I tried below but nothing works.

1. Modifying cwd

In "SubModule_a.py",

import os
os.chdir("C:\\work\\Folder Main")
import MainModule

This still arises ModuleNotFoundError

2. Modifying "MyWorkspace.code-workspace"

   "settings": {

    "python.pythonPath": "C:\\anaconda3\\envs\\MyEnv\\python.exe", # for virtual env
    "python.linting.pylintEnabled": true,
    "python.linting.enabled": true,
    "terminal.integrated.cwd": "C:\\work\\Folder Main" # added this line
   

   }

In short, how can I import "MainModule.py" from "SubModule_A.py" without using absolute path?

Answer 1

To import the module successfully, there're two optional ways:

1.Add the following code in launch.json:

"env": {
    "PYTHONPATH":"${workspaceFolder}"
},
"cwd": "${workspaceFolder}"

Then run it through Run without Debugging(Ctrl+F5). It will still throw error if you run by clicking the green triangle button in the upper right corner.

2.Append the current path:

import sys
sys.path.append('./')
from FolderMain import MainModule

When we import a module, python interpreter will search in the current directory, installed built_in modules and third-party modules, the search path is stored in sys.path. ./ represents the current path.

This works both, whatever you run it without debugging or in Terminal.
