正确的相关导入:“无法导入模块" [英] Proper relative imports: "Unable to import module"

问题描述

我有一个这样结构的项目:

<预><代码>.└── 我的应用├── app.py├── 模型│ ├── hello.py│ └── world.py└── 需求.txt

我有两个模型，hello 和 world.这两个模型都是从 app.py 使用的，我像这样导入它们:

from models.hello import Hellofrom models.world import World

但是world也需要使用hello.我在 world.py 中试过这个:

from models.hello import Hello

当我运行应用程序时，上述技术在技术上有效，但 VSCode 的 Python 扩展给了我以下错误:

E0401:无法导入models.hello".

从同一目录导入子模块的正确方法是什么?如何在 VSCode 中避免此错误?

解决方案

您收到的错误是由名为 pylint 的 python linter 报告的.所以这个问题并不是真正特定于 vscode 扩展.

有两种解决方案:

1. 请尝试使用 vape PYTHONPATH=./myapp 在您的项目目录中添加一个 .env 文件，这将告诉 pylint 在哪里可以找到您的模块

2. 或者直接在 vscode 中打开文件夹 myapp 而不是在 vscode 中打开父目录.

I have a project structured like this:

.
└── myapp
    ├── app.py
    ├── models
    │   ├── hello.py
    │   └── world.py
    └── requirements.txt

I have two models, hello and world. Both models are used from app.py where I import them like this:

from models.hello import Hello
from models.world import World

But world also needs to use hello. I tried this in world.py:

from models.hello import Hello

The above technically works when I run the app, but VSCode's Python extension gives me the following error:

E0401:Unable to import 'models.hello'.

What is the proper way of importing a submodule from the same directory? How do I avoid this error in VSCode?

解决方案

The error you are receiving is one that's reported by a python linter named pylint. So the problem isn't really specific to the vscode extension.

There are two solutions:

1. Please try adding an .env file in your project directory with the vape PYTHONPATH=./myapp, this will tell pylint where to find your modules

2. Or just open the folder myapp in vscode directly instead of opening the parent directory in vscode.
