django.core.exceptions.ImproperlyConfigured：错误加载My

我下面Django的教程，很多人问这个问题，但我想我的情况有点特别，因为安装Python-MySQL时我尝试做蟒蛇manage.py执行syncdb我仍然得到这个错误后，

我在virtualenv中，因为我使用的MacPorts来管理我创造了我的virtualenv我的Python安装

virtualenv code/vdjango --no-site-packages --python=/opt/local/bin/python

这个使用MacPorts的我安装前的Django py27-django ，但我的创建后的virtualenv我认为它的更好，我安装Django到VIRTUALENV所以我用pip install django==1.5

据Django的教程中，我编辑我的settings.py文件，然后执行蟒蛇manage.py执行syncdb和我结束了以下错误：

[~/code/vdjango/newsite]$python manage.py syncdb

  Referenced from: /Users/mac-pro/code/vdjango/lib/python2.7/site-packages/_mysql.so
  Reason: image not found

为了证实我有安装python-mysql软件包我跑了PIP重新安装，

(vdjango)mac-pro@localhost:[~/code/vdjango/newsite]$pip install python-mysqldb
Downloading/unpacking python-mysqldb
  Could not find any downloads that satisfy the requirement python-mysqldb
No distributions at all found for python-mysqldb
Storing complete log in /Users/mac-pro/.pip/pip.log

所以发生了什么吗？貌似我有我需要与教程，但一些如何蟒蛇/ Django是抱怨没有MySQLdb的更进一步的一切。

我libmysqlclient.18.dylib位于在/ usr /本地/ MySQL的/ lib目录/但我的系统是在/ usr / lib目录/寻找它。我结束了创建libmysqlclient.18.dylib的符号链接在/ usr / lib目录中，解决了这一问题。

1）确保libmysqlclient.18.dylib中存在的/ usr /本地/ MySQL的/ lib目录/。

打开外壳。

sudo -s
ls /usr/local/mysql/lib/ | grep libmysqlclient.18.dylib

您应该看到的文件：

libmysqlclient.18.dylib

如果没有，在系统中搜索文件的位置：

find / -name libmysqlclient.18.dylib

2.）创建libmysqlclient.18.dylib的在/ usr / lib中的符号链接

在你的shell中输入以下命令：

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

如果您libmysqlclient.18.dylib文件没有位于/ usr /本地/ MySQL的/ lib目录替换第一个路径与正确路径libmysqlclient.18.dylib。

希望帮助。
