【问题描述】：

我最近遇到了我的硬盘驱动器问题，并使用 Disk Utilities 重新安装了 Mac OS 10.7 Lion。 当我去运行我的 Django 应用程序时，出现以下错误：

关于我的开发环境的信息：

我的本​​地开发环境使用 virtualenv 和 virtualenvwrapper。

我在我的虚拟环境中在中检查了以下内容（即在运行这些命令后：workon my_project; cdvirtualenv）：

% which python:  /Users/my_username/Sites/python_projects/my_project/bin/python
>>> import sys
>>> sys.version
'2.7.1 (r271:86832, Jul 31 2011, 19:30:53) \n[GCC 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2335.15.00)]'

% which mysql:  /usr/local/mysql/bin/mysql

>>> import django
>>> django.VERSION
(1, 3, 0, 'final', 0)

我已将注意力集中在使用 Internet 上的各种方法（例如 http://birdhouse.org/blog/2009/09/27/python-mysql-connections-and-snow-leopard/）重新安装 mysql-python 连接器上。没有运气。所有重新安装 mysql-python 的尝试都失败并出现许多错误。不知道为什么无论如何我都需要重新安装mysql-python。

echo $PATH

echo $PYTHONPATH

问题：

关于如何修复的任何提示？ 关于我重新安装 Mac OS 10.7 时发生了什么变化/损坏的任何线索？

任何帮助表示赞赏。谢谢！

【问题讨论】：

如果您可以编辑您的问题以包含您尝试安装 mysql-python 时遇到的错误，这将有所帮助。看到这个：***.com/questions/5671480/….

谢谢@NathanJones。我在尝试安装 mysql-python 时添加了错误。

我花了几天时间解决这个问题，但没有解决。从内存中，我确实设法使用easy_install -U python-mysql 安装了mysql-python，但在尝试使用django 时仍然给我留下“找不到图像”错误。我知道有些人已经成功了，所以可以做到！

【参考方案1】：

你有两个选择：

Manual Install 使用macports

要执行上述任一操作，您需要先安装 xcode - 可从 mac 应用商店下载（免费，但下载 4GB+）。

【讨论】：

谢谢@burhan。在升级到 Lion 之前，让它在没有 macports 的情况下工作。将审查手动安装步骤。
