Django-crontab 在 ec2 ubuntu 虚拟环境中不起作用

Question

我在 mac m1 bigsur 中使用 django-crontab 库

# settings.py
INSTALLED_APPS = [
'django_crontab'
]

CRONJOBS = [
    ('*/5 * * * *', 'diagnoses.croncode.ChangeRegisterView')
]

# croncode.py

def ChangeRegisterView():

我用python manage.py crontab add

它安装在虚拟环境中。 它在本地环境中运行良好。

但是它在 ec2 上不起作用！！ aws ec2安装使用虚拟环境anaconda python=3.8.11版本。
