Question

我想将SQLAlchemy与MySQL数据库一起使用。我创建了引擎并尝试连接但是我收到如下错误。

from sqlalchemy import create_engine
from sqlalchemy.ext.declarative import declarative_base
Engine = create_engine('mysql+mysqldb://dbuser:pass@localhost/mydb')
Base = declarative_base(Engine)

失败并出现错误：

File "/usr/local/lib/python3.2/dist-packages/SQLAlchemy-0.8.0b2-py3.2.egg/sqlalchemy/connectors/mysqldb.py", line 57, in dbapi
return __import__('MySQLdb')
ImportError: No module named MySQLdb

搜索我发现你必须安装MySQLdb for python以便与MySQL一起玩。所以尝试使用 pip-3.2或easy_install-3.2 安装它会失败，如下所示。

sudo pip-3.2 install MySQL-python
Downloading/unpacking MySQL-python
Running setup.py egg_info for package MySQL-python
Traceback (most recent call last):
  File "<string>", line 16, in <module>
  File "/tmp/pip-build/MySQL-python/setup.py", line 14, in <module>
    from setup_posix import get_config
  File "setup_posix.py", line 2, in <module>
    from ConfigParser import SafeConfigParser
ImportError: No module named ConfigParser
Complete output from command python setup.py egg_info:
Traceback (most recent call last):
File "<string>", line 16, in <module>
File "/tmp/pip-build/MySQL-python/setup.py", line 14, in <module>
from setup_posix import get_config
 File "setup_posix.py", line 2, in <module>
from ConfigParser import SafeConfigParser
ImportError: No module named ConfigParser

然后我想我必须安装 configparser 所以当我尝试这样做时它也会失败

Original exception was:
Traceback (most recent call last):
 File "<string>", line 3, in <module>
 File "/usr/local/lib/python3.2/dist-packages/distribute-0.6.34-py3.2.egg/setuptools/__init__.py", line 2, in <module>
from setuptools.extension import Extension, Library
File "/usr/local/lib/python3.2/dist-packages/distribute-0.6.34-py3.2.egg/setuptools/extension.py", line 2, in <module>
import distutils.core
File "/usr/lib/python3.2/distutils/core.py", line 19, in <module>
from distutils.config import PyPIRCCommand
File "/usr/lib/python3.2/distutils/config.py", line 8, in <module>
from configparser import ConfigParser
 File "configparser.py", line 122

所以，我最初的问题是试图让Python与MySQL一起工作。但试图解决我无法安装MySQLdb。

修改按照下面@robertklep的指示前进并安装了pymsql3。

sudo pip-3.2 install pymysql3

此致

Answer 1

MySQLdb没有Python 3支持。尝试一种替代方案，例如PyMySQL（supported by SQLAlchemy as well）。

编辑：还有this project。

Answer 2

https://www.pythonanywhere.com/wiki/UsingMySQL

pip install --user https://dev.mysql.com/get/Downloads/Connector-Python/mysql-connector-python-1.1.6.tar.gz

然后，更新您的settings.py以使用oracle django后端，＆＃34; mysql.connector.django＆＃34;：

DATABASES = {
    'default': {
        'ENGINE': 'mysql.connector.django',
         ...

Python3.2：安装MySQL-python失败，错误“没有名为ConfigParser的模块”
