I want to get rid of import warnings from Pyright and pylint in VS Code

This is a solution when you want to switch the environment variable PYTHONPATH for each of multiple folders in the same workspace (but you don't know how to switch).

"Import'xxx' could not be resolved Pyright (report Missing Imports)" warning from Pyright If the warning "Unable to import'xxx' pylint (import-error)" is displayed from pylint, you can change the search folder to be imported for each folder.

Also, even if there are import targets with the same name in multiple folders in the same workspace, proper syntax check and character completion will be effective.

I wanted to easily crush the import warning without dividing the workspace or using the virtual environment with venv, so I searched variously, but I could not find the topic of the same case, so I decided to make a trial and error. , Post as a memorandum.

Folder structure (example)

src/
├── project1/
│   ├── .env (added this)
│   ├── .vscode/
│   │   └── settings.json (added this)
│   ├── project_root/
│   │   └── python_src/
│   │       ├── file1.py
│   │       └── file2.py
│   └── pyrightconfig.json (added this)
├── project2/
│   ├── .env (added this)
│   ├── .vscode/
│   │   └── settings.json (added this)
│   ├── project_root/
│   │   └── python_src/
│   │       ├── file1.py
│   │       └── file2.py
│   └── pyrightconfig.json (added this)
└── server_library/
    └── python_src/
        └── file3.py

Settings for Pyright

Place "pyrightconfig.json" for each folder you want to switch PYTHONPATH directly under the workspace.

src/project1/pyrightconfig.json

{
  "executionEnvironments": [
    {
      "root": "project_root",
      "extraPaths": [
        "project_root/python_src",
        "../server_library/python_src"
      ]
    }
  ]
}

Settings for pylint

• For each folder you want to switch PYTHONPATH directly under the workspace, specify the environment variable setting file in "python.envFile" as the VS Code folder setting.

json:src/project1/.vscode/settings.json

{
    "python.envFile": "/(Path up to here)/src/project1/.env"
}

• Place the environment variable setting file.

src/project1/.env

PYTHONPATH=/(Path up to here)/src/server_library/python_src:/(Path up to here)/src/project1/project_root/python_src

Assumed conditions

• Multiple folders in the same workspace contain items that you want to import with the same name. (Similar but different)
• I want to import from the sources of multiple folders in the same workspace in common, but I want to separate PYTHONPATH.
• I don't want to divide the workspace.
• venv I'm not using a virtual environment.
• Use VS Code on Mac. (Current situation on 02/08/2020)
• I want to manage multiple similar but different projects in one workspace at hand and take advantage of syntax checking.
