我有一个奇怪的问题，当我试图从django_celery_beat添加一个任务包放在我的生产服务器上。(我的本地工作空间一切正常)。
我得到一个No module named pymemcache错误，但我已经在我的venv上安装了它。
在我的生产服务器上，我有一个memcached服务器在运行，配置如下:
'default': {
'BACKEND': 'django.core.cache.backends.memcached.PyMemcacheCache',
'LOCATION': '10.100.23.95:11211',
},
如何解决这个问题?
非常感谢您的宝贵时间
我试着重新安装软件包，但是我不明白我做错了什么。

试试这个:
pip install pymemcache
我找到错误了。
如果您有一个jelastic云生产服务器，请验证服务器正在使用的venv。
我使用的是一个不同的(默认的jelastic而不是我创建的)。
一个快速的解决办法是在venv之外运行pip install pymemcache。
