# sqlalchemy.exc.ArgumentError: Could not parse SQLAlchemy URL from string 'sqlite:////tmp/test.db'

- **ID:** `python/sqlalchemy-invalid-sqlite-url`
- **Domain:** python
- **Category:** config_error
- **Verification:** ai_generated
- **Fix Rate:** 80%

## Root Cause

Incorrect number of slashes in SQLite URL; four slashes indicate absolute path, three for relative path, but misplacement often occurs.

## Version Compatibility

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

## Workarounds

1. **** (100% success)
   ```
   engine = create_engine('sqlite:////tmp/test.db')  # absolute
# or
engine = create_engine('sqlite:///./test.db')  # relative
   ```

## Dead Ends

- **** — Changes path interpretation; may point to wrong file. (50% fail)
- **** — Makes it a relative path unexpectedly. (40% fail)
