我想用这个命令heroku run python manage.py migrate更新我的heroku站点，但是出现了错误：

»   Warning: heroku update available from 7.53.0 to 7.60.2.

ModuleNotFoundError: No module named 'django_apscheduler'

我用pip install django_apscheduler安装了django_apscheduler。我的python版本是3.10.2，在我的settings.py中，应用模块在INSTALLED_APPS中，例如：

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'myapp'
    'django_apscheduler',
]

我不知道为什么会发生ModuleNotFoundError，任何帮助都将不胜感激。
