我的目录结构如下：
├── person
└── __init__.py
└── person.py
└── tests
└── test_person.py
├── setup.py
setup.py：
from setuptools import setup, find_packages
setup(name="person", packages=find_packages())
person.py：
import team
class Person:
def __init__(self, fname, lname):
self.fname = fname
self.lname = lname
print("hello")
test_person.py：
from person import Person
def test_person():
p = Person("john", "smith")
assert p.fname == "john"
安装我的软件包后：
$ pip install -e .

我遇到此错误：

如果我将导入修改为from person.person import Person，则它将运行。我如何才能做到只需要from person import Person？
编辑： @hoefling的建议效果很好，但是如果我的ModuleNotFoundError: No module named 'team'导入了person.py，我遇到一个team错误。我该如何修改__init__.py以便pytest可以选择另一个模块？
team.py
class Team:
def __init__(self, name):
self.name = name
这有效：
$ python3 person/person.py
hello
这不是：
$ pytest
