我试图在centos machine中运行现有的项目。我从requirements.txt安装了包并安装成功但运行“python manage.py runserver”我得到以下回溯。python _mysql_exceptions.ProgrammingError：（2014，“Commands out of sync; you can not run this command now”）

重新安装python-mysql的 – Nilesh

@NileshG为什么重新安装python-mysql的。 Mysql配置正确，我能够通过命令提示符查看数据库。我安装了mysql连接器1.2.3。更多我分别安装了mysql和python。 – user2681579

如果我也运行syncdb，我得到相同的错误 – user2681579

-1

您可以尝试在现有的数据库上运行 -

python manage.py inspectdb

这将输出新models.py，现在你的models.py比较新生成的models.py

我加倍检查now.I运行此命令时遇到同样的错误。需要帮助解决。 – user2681579

我可以得到最后一个命令的任何更新。 – user2681579

如果你想许多执行SQL语句，不使用cur.execute(sql)

更好的方法是使用cur.executemany(sql)

EXP 1：这将导致一些错误

sql = "insert into test(name, age) value('Joe', '28');insert into test(name, age) value('xxtime', '15');" 
    cursor = db.cursor() 
    cursor.execute(sql) 
    db.commit()

EXP 2：你可以用它来代替

sql = "insert into test(name, age) value(%s, %s);" 
    cursor = db.cursor() 
    cursor.executemany(sql,[('Joe', '28'),('xxtime', '15')]) 
    db.commit()
