generic

解决方案

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

无效尝试

常见但无效的做法:

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

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

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

    Dialect names are case-sensitive and must match exactly.
