Django-crontab不在ec2 ubuntu虚拟环境中工作。

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():

我用了python manage.py crontab add

它安装在虚拟环境中。而且它在当地环境中运行得很好。

但是它在ec2不起作用！虚拟环境anaconda python=3.8.11版本由aws ec2安装和使用。

像这样

我想做两件事。

1. 我想在ec2 Ubuntu环境中执行cronlog路径。
2. 我想在ec2.

中转。

救救兄弟们！

下面是使用django-crontab (Mac，Linux)在django中添加cronjob的步骤

1. 安装软件包

django-crontab安装pip3

如果这给出并发出问题，那么执行卸载命令或强制安装

python3 -m pip install django-crontab

在INSTALLED_APPS中添加

1. 'django_crontab‘

1. 在您的应用程序

中创建新的crons.py文件

1. 在crons.py中添加您的cronjob方法，例如

1. 在settings.py文件中添加以下配置

CRON作业设置

CRONJOBS = ('*/1 ** *'，'your_app_name.crons.your_cronjob_method')，
