如何解決這個Django/MySQL安裝程序災難？

Question

我一直在搜索SO，論壇和博客文章超過24小時。坦率地說，我完全不知道發生了什麼事。這似乎是一個複雜的問題，所以我會盡可能清楚地發佈。

我正在使用Django，並試圖從sqlite切換到mysql。我跟着從這個指令，以便回答這樣做：https://stackoverflow.com/a/3036241

當我運行的最後一行，python manage.py loaddata datadump.json（或當我嘗試爲此事跑python manage.py syncdb），我收到以下錯誤：

File "manage.py", line 10, in <module> 
execute_from_command_line(sys.argv) 
    File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/Django-1.4-py2.7.egg/django/core/management/__init__.py", line 443, in execute_from_command_line

    backend = load_backend(connection.settings_dict['ENGINE']) 
    File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/Django-1.4-py2.7.egg/django/db/__init__.py", line 34, in __getattr__ 
    return getattr(connections[DEFAULT_DB_ALIAS], item) 
    File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/Django-1.4-py2.7.egg/django/db/utils.py", line 92, in __getitem__ 
    backend = load_backend(db['ENGINE']) 
    File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/Django-1.4-py2.7.egg/django/db/utils.py", line 24, in load_backend 
    return import_module('.base', backend_name) 
    File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/Django-1.4-py2.7.egg/django/utils/importlib.py", line 35, in import_module

    raise ImproperlyConfigured("Error loading MySQLdb module: %s" % e) 
django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module: No module named MySQLdb 

所以，我找遍四周，看看如何解決這個問題，並試圖這樣：一旦

pip install MySQL-python 

爲我跑這條線，我得到了以下錯誤：

Downloading/unpacking MySQL-python 
    Running setup.py egg_info for package MySQL-python 
    sh: mysql_config: command not found 
    Traceback (most recent call last):

     File "/var/folders/9q/bvqtzkbx1hg1934b36zgk0y40000gn/T/pip-build/MySQL-python/setup.py", line 18, in <module> 
     metadata, options = get_config() 
     File "setup_posix.py", line 43, in get_config 
     libs = mysql_config("libs_r") 
     File "setup_posix.py", line 25, in mysql_config 
     raise EnvironmentError("%s not found" % (mysql_config.path,)) 
    EnvironmentError: mysql_config not found 
    Complete output from command python setup.py egg_info:

    metadata, options = get_config() 

    File "setup_posix.py", line 43, in get_config 

    libs = mysql_config("libs_r") 

    File "setup_posix.py", line 25, in mysql_config 

    raise EnvironmentError("%s not found" % (mysql_config.path,)) 

EnvironmentError: mysql_config not found 

用easy_install試過，只是爲了確認。同樣的錯誤。

所以，然後我試圖改變的路徑中setup_posix.py到mysql_config，通過以下步驟5和6從該SO回答：https://stackoverflow.com/a/1448476/1337422

當我轉移到步驟7該答案的 ，跑sudo python setup.py build，我得到了以下錯誤：

unable to execute gcc-4.0: No such file or directory 
error: command 'gcc-4.0' failed with exit status 1 

對於這一點，我發現沒有治癒。

順便說一句，我也跟着指示，這個答案：https://stackoverflow.com/a/1448446/1337422，跑： sudo port install py26-mysql

這似乎有固定的什麼都沒有。

（我在Mac OS 10.8.1上運行）

我這麼丟了，在這一點上如此絕望。我不知道還有哪些地方可以幫助我......幫助我！

Answer 1

的線索是在這裏：

unable to execute gcc-4.0: No such file or directory 
error: command 'gcc-4.0' failed with exit status 1 

您需要安裝編譯器...我不是一個Mac用戶，但快速谷歌想出了http://www.tech-recipes.com/rx/726/mac-os-x-install-gcc-compiler/這可能有助於

看起來像sudo port install gcc_select然後sudo port install gcc<nnn>大概是正確的...
