# django.core.cache.backends.base.InvalidCacheBackendError: Could not find backend 'django.core.cache.backends.memcached.MemcachedCache': ModuleNotFoundError: No module named 'memcache'

- **ID:** `python/django-cache-miss-error`
- **Domain:** python
- **Category:** module_error
- **Verification:** ai_generated
- **Fix Rate:** 80%

## Root Cause

Memcached Python client library is not installed.

## Version Compatibility

| Version | Status | Introduced | Deprecated |
|---------|--------|------------|------------|
| 3.x | active | — | — |

## Workarounds

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

## Dead Ends

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