AttributeError:模块‘mysql’没有属性‘connector’

I'm running Ubuntu 16.04, trying to connect to mysql in python:

我正在运行Ubuntu 16.04，试图用python连接到mysql:

    import mysql
    username = 'root'

    cnx = mysql.connector.connect(user=username, database='db')
    cnx.close()

But I get an error:

但我犯了一个错误:

    File "pysql1.py", line 4, in <module>
      cnx = mysql.connector.connect(user=username, database='db')
    AttributeError: module 'mysql' has no attribute 'connector'

I installed the mysql python module by downloading the package here. I tried sudo apt-get install python-mysql.connector to no avail. Any pointers?

我在这里下载了这个包，安装了mysql python模块。我尝试了sudo apt-get install python-mysql。连接器都无济于事。指针吗?

EDIT: after adding import mysql.connector I got an unrelated permissions error which I've now resolved, so that's what I needed ty lots!!!

编辑:添加导入mysql后。连接器我有一个不相关的权限错误，我现在已经解决了，所以我需要大量的ty !!

2 个解决方案

#1

The solution is to execute :

解决办法是:

import mysql.connector # or from mysql import connector

Because the module connector is only available when you import it explicitly :

因为模块连接器只有在显式导入时才可用:

import mysql

print(dir(mysql))
>>> ['__builtins__', '__cached__', '__doc__', '__file__', '__loader__', '__name__', 
'__package__', '__path__', '__spec__']

import mysql.connector

print(dir(mysql))
>>> ['__builtins__', '__cached__', '__doc__', '__file__', '__loader__', '__name__', 
'__package__', '__path__', '__spec__', 'connector']

The __init__ file in the module mysql doesn't import the module connector.

mysql模块中的__init__文件没有导入模块连接器。

mysql
|_______ __init__.py # no import at this level
|_______ connector
         |________ __init__.py

This could work implicitly if connector was imported inside __init__ with : from . import connector.

如果连接器在__init__中导入:from，则可以隐式地工作。进口连接器。

I was still getting the same error after import mysql.connector and checking permissions. I was running my script on MacOS using bash. After hours of searching for a solution, came across this post on the mysql forums: https://forums.mysql.com/read.php?50,584171,584729#msg-584729

我在导入mysql后仍然得到相同的错误。连接器和检查权限。我使用bash在MacOS上运行脚本。在花了几个小时寻找解决方案之后，我在mysql论坛上看到了这篇文章:https://forums.mysql.com/read.php?

The poster mentions that your python script can't be named mysql.py My script was named types.py, so I renamed it to setup-types.py and that solved my problem. Hopefully this saves others some time when dealing with this same error.

海报中提到您的python脚本不能命名为mysql。我的脚本被命名为types。py，所以我将它重命名为setup-type。这就解决了我的问题。希望这能在处理相同的错误时为其他人节省一些时间。
