未安装 Memcached Python 客户端库。

## 版本兼容性

## 解决方案

1. **** (90% 成功率)
   ```
   pip install python-memcached
   ```
2. **** (80% 成功率)
   ```
   Use django.core.cache.backends.locmem.LocMemCache for development instead.
   ```

## 无效尝试

- **** — Changing CACHE_BACKEND to locmem without installing memcached doesn't solve if you need memcached. (50% 失败率)
- **** — Installing wrong package (e.g., memcache vs python-memcached) can cause import errors. (70% 失败率)
