Mac OS X 10.6、Mysql、Mysql Python、Django 更新：

我看到了这篇文章：看到了两种选择：

将MySQL客户端库添加到LD_LIBRARY_路径

mysql_config--libs -L/usr/local/mysql/lib-lmysqlclient-lpthread

所以我不需要在这里做任何事情

只需要升级到Python 2.7，然后重新安装mysqldb

问题: 成功安装django并运行VirtualEnvironment，并使用sqlite3创建项目。我想用mysql来管理数据库

设置.py

DATABASES = {
     'default': {
         'ENGINE': 'django.db.backends.mysql', # Add 'postgresql_psycopg2', 'postgresql', 'mysql', 'sqlite3' or 'oracle'.
         'NAME': 'blog',                      # Or path to database file if using sqlite3.
         'USER': 'root',                      # Not used with sqlite3.
         'PASSWORD': 'root',                  # Not used with sqlite3.
         'HOST': 'localhost',                      # Set to empty string for localhost. Not used with sqlite3.
         'PORT': '',                      # Set to empty string for default. Not used with sqlite3.
     } }

这让我很沮丧：表演之后：

sudo python manage.py runserver

我得到的错误是：

•   Stop the database server
•   sudo rm /usr/local/mysql
•   sudo rm -rf /usr/local/mysql*
•   sudo rm -rf /Library/StartupItems/MySQLCOM
•   sudo rm -rf /Library/PreferencePanes/My*
•   edit /etc/hostconfig and remove the line MYSQLCOM=-YES-
•   rm -rf ~/Library/PreferencePanes/My*
•   sudo rm -rf /Library/Receipts/mysql*
•   sudo rm -rf /Library/Receipts/MySQL*
•   sudo rm -rf /private/var/db/receipts/*mysql*

~/.bash\u配置文件包含

export PATH=/usr/local/mysql/bin:$PATH
export EDITOR="$HOME/bin/mate -w"
export DYLD_LIBRARY_PATH=/usr/local/mysql/lib/

如果我这样做了

python shell
import MySQLdb

这不显示任何内容

使用pip卸载mysql python，然后从源代码重新编译：

我哪里出了问题，是因为mysql客户端没有正确配置此版本的mysql python吗？

我通常在Mac上使用自制软件安装mysql（这是一个非常轻松的过程），并且“找不到映像”是我记得在升级mysql版本后没有重新安装mysql python时看到的

我的建议是卸载MySQL和MySQL python，安装并运行：

brew install mysql
pip install MySQL-python

sudo ln-s/usr/local/mysql/lib/libmysqlclient.18.dylib/usr/lib/libmysqlclient.18.dylib

谢谢你的回复，但我确实找到了解决问题的方法。理解错误消息后，我只需要创建一个libmysqlclient.18.dylib文件的符号，如下所示：sudo ln-s/usr/local/mysql/lib/libmysqlclient.18.dylib/usr/lib/libmysqlclient.18.dylib
