Python3.2：安装MySQL-python失败，出现错误“No module named ConfigParser”

我想在MySQL数据库中使用SQLAlchemy。我创建了引擎并尝试连接，但出现如下错误。Python3.2：安装MySQL-python失败，出现错误“No module named ConfigParser”

from sqlalchemy import create_engine 
from sqlalchemy.ext.declarative import declarative_base 
Engine = create_engine('mysql+mysqldb://dbuser:[email protected]/mydb') 
Base = declarative_base(Engine)

失败，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，你必须有安装MySQLdb的Python的发挥好与MySQL。所以试图用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:

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，它也失败

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 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，我原来的问题是试图让Python来使用MySQL的。但试图解决，我无法安装MySQLdb。

编辑按照以下@robertklep的指示前进并安装了pymsql3。

sudo pip-3.2 install pymysql3

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

编辑：还有this project。

感谢您的。昨天浪费了整整一天。我看到有pymysql3和pymysql_sa，它声明pymysql_sa是SQLAlchemy的PyMySQL方言。那么我应该安装哪个？鉴于pymysql_sa与sqlalchemy特别合作，pymysql_sa更有优势吗？ – lukik 2013-03-01 10:17:36

发现了“硬道路”。尝试安装pymysql_sa并失败。最有可能的是它与Python3不兼容。所以，是的，坚持与pymysql3。谢谢。 – lukik 2013-03-01 10:23:09

我尝试使用pymysql3和我[遇到问题]（http://stackoverflow.com/questions/15170450/sqlalchemypymysql-error-sqlalchemy-util-queue-empty），正如指出sqlalchemy有一个错误。你有解决方法吗？ – lukik 2013-03-03 04:45:20

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使用Oracle Django的后端， “mysql.connector.django”：

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

试图在此之后，我得到了“django.core.exceptions.ImproperlyConfigured：‘mysql.connector.django’不是一个可用的数据库后端” – 2015-08-10 12:50:11
