Django開發環境破壞以下Mac OS 10.7重新安裝

Question

我最近遇到了硬盤驅動器的問題，並使用Disk Utilities重新安裝Mac OS 10.7 Lion。
當我去跑我的Django應用程序，我得到了以下錯誤：

INFO關於我的開發環境：

我的本地開發環境使用的virtualenv和virtualenvwrapper。

我檢查從以下（運行這些命令後，即：workon my_project; cdvirtualenv）：內我的虛擬環境

% 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) 

我集中我的注意使用不同的配方重新安裝mysql-python連接器（例如http://birdhouse.org/blog/2009/09/27/python-mysql-connections-and-snow-leopard/）在互聯網上找到。沒有運氣。所有重新安裝mysql-python的嘗試都會失敗，並帶來許多錯誤。不知道爲什麼我需要重新安裝mysql-python。

echo $PATH 
----------- 
/Users/my_username/Sites/python_projects/my_project/bin:/opt/subversion/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/opt/local/bin:/usr/local/git/bin:/usr/local/mysql/bin:/Developer/usr/bin 


echo $PYTHONPATH 
----------------- 
/Users/my_username/lib/python 

問題：

• 有關如何解決任何提示嗎？
• 當我重新安裝Mac OS 10.7時，有關更改/打破的任何線索？

任何幫助讚賞。謝謝！

Answer 1

你有兩個選擇：

1. Manual Install
2. 使用macports

要做任一其中，您需要先安裝xcode - 可從mac應用商店購買（免費，但4GB +下載）。
