Error debugging Python in VS Code: "pythonPath" is not valid if "python" is specified

问题

I get a prompt with:

  1. "pythonPath" is not valid if "python" is specified

and the option to open launch.json. But my launch.json doesn't contain anything that says "pythonPath":

  1. {
  2.   "configurations": [
  3.     {
  4.       "name": "Docker: Python - General",
  5.       "type": "docker",
  6.       "request": "launch",
  7.       "preLaunchTask": "docker-run: debug",
  8.       "python": {
  9.         "pathMappings": [
  10.           {
  11.             "localRoot": "${workspaceFolder}",
  12.             "remoteRoot": "/app"
  13.           }
  14.         ],
  15.         "projectType": "general"
  16.       }
  17.     }
  18.   ]
  19. }

and this is my tasks.json:

  1. {
  2.   "version": "2.0.0",
  3.   "tasks": [
  4.     {
  5.       "type": "docker-build",
  6.       "label": "docker-build",
  7.       "platform": "python",
  8.       "dockerBuild": {
  9.         "tag": "cachepurger:latest",
  10.         "dockerfile": "${workspaceFolder}/Dockerfile",
  11.         "context": "${workspaceFolder}",
  12.         "pull": true
  13.       }
  14.     },
  15.     {
  16.       "type": "docker-run",
  17.       "label": "docker-run: debug",
  18.       "dependsOn": ["docker-build"],
  19.       "python": {
  20.         "file": "src/main.py"
  21.       }
  22.     }
  23.   ]
  24. }

and the Dockerfile:

  1. # For more information, please refer to https://aka.ms/vscode-docker-python
  2. FROM python:3.9.6-slim
  4. # Keeps Python from generating .pyc files in the container
  5. ENV PYTHONDONTWRITEBYTECODE=1
  7. # Turns off buffering for easier container logging
  8. ENV PYTHONUNBUFFERED=1
  10. # Install pip requirements
  11. COPY requirements.txt .
  12. RUN python -m pip install -r requirements.txt
  14. WORKDIR /app
  15. COPY . /app
  17. # Creates a non-root user with an explicit UID and adds permission to access the /app folder
  18. # For more info, please refer to https://aka.ms/vscode-docker-python-configure-containers
  19. RUN adduser -u 5678 --disabled-password --gecos "" appuser && chown -R appuser /app
  20. USER appuser
  22. # During debugging, this entry point will be overridden. For more information, please refer to https://aka.ms/vscode-docker-python-debug
  23. CMD ["python", "src/main.py"]

all created by the "Docker: Add Dockerfiles to Workspace..." -> "Python: General" command. It worked before but stopped working now. I tried to use Python 3.9.6 image, since that is the one from my .venv but no success. The image gets built without an error and also docker run works fine. The moment it tries to "attach" I get this message.

This is the terminal output:

答案1

得分: 9

你的代码没问题。问题出在 VSCode / Python 扩展程序已更新至分别为 1.75 和 2023.02，因此出现了这个新的错误。请参考此问题以获得有关此错误的持续开发信息。目前，卸载 VSCode，重新安装 1.74 版本，然后在 2023.02 之前重新安装 Python 扩展程序，应该就可以解决问题。

英文:

Your code is fine. It's VSCode / Python Extension that got updated to version 1.75 and 2023.02 respectively and hence this error is new. Please refer to this issue for constant development on the bug. As for now, uninstall VSCode and re-install 1.74, and re-install the python extension before 2023.02 and you should be good to go.

得分: 3

今天是2023年3月2日，我已经切换到Python扩展的预发布版本，它可以正常工作。我相信这个问题将在下一个Python扩展版本中得到解决。目前，你可以手动切换扩展版本。

“Error debugging Python in VS Code: ‘pythonPath’ is not valid if ‘python’ is specified.”

英文:

Today march 2, 2023, I've switched to the pre-release version of python extension and it works, sure it will be solved in next python extension version, for now, you can switch manually the extension version.“Error debugging Python in VS Code: ‘pythonPath’ is not valid if ‘python’ is specified.”
