ModuleNotFoundError: No module named 'manage_crypto_currency'

在尝试调试应用程序“manage_crypto_currency”中的tests.py文件时，我遇到了上述错误

__init.py（应用程序“管理加密货币”）：

tests.py（应用程序“管理加密货币”）：

我想做一些普通的python测试/调试。我不明白为什么：

ModuleNotFoundError: No module named 'manage_crypto_currency'

被抛出

import os

from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()
os.environ["DJANGO_ALLOW_ASYNC_UNSAFE"] = "true"

from django.test import TestCase
from crypto.manage_crypto_currency.get_coins_scheduler import do_greeting


if do_greeting():
    print("Online")
else:
    print("Offline/API changed")

ModuleNotFoundError: No module named 'manage_crypto_currency'
