Pylint报告具有嵌套结构的项目的错误导入错误

如何解决Pylint报告具有嵌套结构的项目的错误导入错误

我的Python Chalice项目运行正常,我的所有测试都通过了,但是Pylint正在报告unresolved import错误。

我在具有以下项目结构的普通Python项目上重现了该错误:

myproject
    .vscode
        settings.json
    /api
        /domain
            __init__.py
            weekday.py
        __init.py
        app.py
    /tests
        /api
            /domain
                __init__.py
                test_weekday.py
            __init__.py
        __init__.py

.vscode/settings.json

{
    "python.pythonPath": "C:\\Users\\Admin\\AppData\\Local\\Programs\\Python\\Python38\\python.exe"
}

weekday.py

from enum import Enum


class Weekday(Enum):
    MONDAY = 'mon'
    TUESDAY = 'tue'
    WEDNESDAY = 'wed'
    THURSDAY = 'thu'
    FRIDAY = 'fri'


class InvalidValue(Exception):
    pass


def parse(key: str) -> Weekday:
    try:
        return Weekday(key)
    except Exception as e:
        raise InvalidValue() from e

app.py

from domain.weekday import Weekday


if __name__ == '__main__':
    print(Weekday.MONDAY.value)

    print('done!')

test_weekday.py

from unittest import TestCase

from api.domain import weekday
from api.domain.weekday import Weekday


class StateTests(TestCase):
    def test_validParsing(self):
        self.assertEqual(weekday.parse('mon'),Weekday.MONDAY)
        self.assertEqual(weekday.parse('tue'),Weekday.TUESDAY)
        self.assertEqual(weekday.parse('wed'),Weekday.WEDNESDAY)
        self.assertEqual(weekday.parse('thu'),Weekday.THURSDAY)
        self.assertEqual(weekday.parse('fri'),Weekday.FRIDAY)

    def test_invalidParsing(self):
        with self.assertRaises(weekday.InvalidValue):
            weekday.parse('invalid value')

以下是我的Python特定的VS Code设置:

"python.languageServer": "Microsoft","python.linting.pylintEnabled": true,"python.linting.pylintUseMinimalCheckers": false,"python.linting.pylintArgs": [
    "--disable=C0111"
],"python.pythonPath": "C:\\Users\\Admin\\AppData\\Local\\Programs\\Python\\Python38\\python.exe","python.linting.mypyCategorySeverity.note": "Warning","python.linting.mypyEnabled": true

我使用python api/app.py运行我的香草Python应用程序,并使用python -m unittest -f运行测试。

在我上面的香草Python项目上,我得到以下错误和警告(测试未报告任何问题,这很奇怪):

app.py
    ERROR: Unable to import 'domain.weekday' pylint(import-error)
    WARNING: unresolved import 'domain.weekday' Python(unresolved-import)

在我的Python Chalice项目中,我收到以下错误和警告:

app.py
    ERROR: Unable to import 'domain' pylint(import-error)
    WARNING: unresolved import 'domain' Python (unresolved-import)
test_weekday.py
    ERROR: Unable to import 'api.domain' pylint(import-error)
    ERROR: Unable to import 'api.domain.weekday' pylint(import-error)

同样,两个应用程序都可以正常工作,并且我所有的测试都通过了。

我尝试将以下内容添加到我的.vscode/settings.json中,但这无济于事:

{
    "python.autoComplete.extraPaths": [
        "./api","./tests"
    ],}

如何配置Pylint使其在此项目结构中正常工作?

解决方法

我创建了与您提供的文件夹结构相同的项目,以及相同的设置。除了pylint警告,没有其他问题:

enter image description here

添加以下设置可以禁用这些警告:

    "python.analysis.disabled": [
        "unresolved-import",],"python.linting.pylintArgs": [
        "----extension-pkg-whitelist=1xml"
    ],

enter image description here

有关pylint的更多详细信息,请参阅Readable Pylint Messages

[编辑]

设置"python.languageServer": "Jedi",也可以禁用这些警告。

或在launch.json中添加配置:
