我嘗試使用此代碼使用pymsql與SQLAlchemy的：錯誤：沒有重複

 
    from sqlalchemy import create_engine 
    engine = create_engine("mysql+pymsql://root:@localhost/pydb") 
    conn = engine.connect()

這種異常在這裏提出的是完整的堆棧跟蹤：

在您的用戶名後，從連接字符串中刪除:。應該改爲mysql+pymsql://[email protected]/pydb

我試着刪除它，但問題依然存在。 – naguib

對不起，我沒有先測試。你正在使用Python 3.3和SQLAlchemy 9.2？ – ACV

是的。這可能與使用這些版本有關嗎？ – naguib

我工作的URI SQLAlchemy的0.9.4和python3.3是：

sqlalchemy.url = mysql+pymysql://user:[email protected]:port/database?charset=utf8&use_unicode=0

我用pymysql代替pymsql的。
