我想在MySQL數據庫中使用SQLAlchemy。我創建了引擎並嘗試連接,但出現如下錯誤。Python3.2:安裝MySQL-python失敗,出現錯誤「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)
失敗,出現錯誤:
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,我發現,你必須有安裝MySQLdb的Python的發揮好與MySQL。所以試圖用pip-3.2或easy_install-3.2安裝它會失敗,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
然後我想,我必須安裝configparser所以當我嘗試這樣做,它也失敗
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>

File "/usr/lib/python3.2/distutils/config.py", line 8, in <module>
from configparser import ConfigParser

所以,我原來的問題是試圖讓Python來使用MySQL的。但試圖解決,我無法安裝MySQLdb。
編輯 按照以下@robertklep的指示前進並安裝了pymsql3。
sudo pip-3.2 install pymysql3
問候,
感謝您的。昨天浪費了整整一天。我看到有pymysql3和pymysql_sa,它聲明pymysql_sa是SQLAlchemy的PyMySQL方言。那麼我應該安裝哪個?鑑於pymysql_sa與sqlalchemy特別合作,pymysql_sa更有優勢嗎? – lukik 2013-03-01 10:17:36
發現了「硬道路」。嘗試安裝pymysql_sa並失敗。最有可能的是它與Python3不兼容。所以,是的,堅持與pymysql3。謝謝。 – lukik 2013-03-01 10:23:09
我嘗試使用pymysql3和我[遇到問題](http://stackoverflow.com/questions/15170450/sqlalchemypymysql-error-sqlalchemy-util-queue-empty),正如指出sqlalchemy有一個錯誤。你有解決方法嗎? – lukik 2013-03-03 04:45:20
