Root Cause

Missing or misconfigured database driver (e.g., psycopg2 not installed).

generic

中文

缺少或配置错误的数据库驱动程序（例如，未安装 psycopg2）。

Workarounds

  1. 95% success Install the correct driver. 
    pip install psycopg2-binary
  2. 90% success Use correct connection string format. 
    engine = create_engine('postgresql://user:pass@localhost/dbname')

Dead Ends

Common approaches that don't work:

  1. Installing wrong package like 'postgresql' instead of 'psycopg2-binary'. 70% fail

    SQLAlchemy requires specific driver packages; generic packages don't work.

  2. Setting incorrect dialect string like 'postgres' instead of 'postgresql'. 80% fail

    Dialect names are case-sensitive and must match exactly.
