Python ModuleNotFoundError:没有名为'；app&x27；在Windows虚拟环境中尝试使用Pytest和Flask创建测试时

我正在尝试使用为我的Flask应用程序创建测试，但当我使用pytest运行测试时，它抛出以下错误：

Hint: make sure your test modules/packages have valid Python names.
Traceback:
test\test_flask.py:6: in <module>
    from app import app
E   ModuleNotFoundError: No module named 'app'

和init.py:

from flask import Flask, request, jsonify
from config import Config
from flask_sqlalchemy import SQLAlchemy
from flask_migrate import Migrate
from werkzeug.security import generate_password_hash, check_password_hash
from flask_jwt_extended import (
    JWTManager, jwt_required, create_access_token,
    get_jwt_identity
)
from flask_cors import CORS

app = Flask(__name__)
app.config.from_object(Config)
db = SQLAlchemy(app)
migrate = Migrate(app, db)
jwt = JWTManager(app)
CORS(app)
app.config['CORS_HEADERS'] = 'Content-Type'


from app import routes, models

mymanhualist.py：

from app import app

我已经解决了在项目的根目录中创建setup.py并构建我的包的问题，以便测试目录可以访问应用程序包

setup.py：

import setuptools

with open("README.md", "r") as fh:
    long_description = fh.read()

setuptools.setup(
    name="appPackage-YourUser", 
    version="0.0.1",
    author="Your Name",
    author_email="yourownemail@email.com",
    description="",
    long_description=long_description,
    long_description_content_type="text/markdown",
    url="https://github.com/luturol/MyManhuaListAPI",
    packages=setuptools.find_packages(),
    classifiers=[
        "Programming Language :: Python :: 3",
        "License :: OSI Approved :: MIT License",
        "Operating System :: OS Independent",
    ],
    python_requires='>=3.6',
)

刚跑完后：

pip install -e .
