这与 a previous question 有关.
但是，那里发布的主要解决方案对我不起作用。我在雪豹上，使用 32 位 5.1.49 MySQL dmg 安装。 我正在使用内置的 python(显然，如评论中所述，我的 Python 版本不同)，它似乎是 2.6.5 32 位:
Python 2.6.5 (r265:79359, Mar 24 2010, 01:32:55) [GCC 4.0.1 (Apple Inc. build 5493)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import sys >>> sys.maxint 2147483647
我已经从 the usual location 下载了 MySQL-python 1.2.3。并更改了 site.cfg 以便 mysql_config 指向正确的位置并且 registry_key 指令被注释掉。这些软件包似乎可以很好地构建和安装:

但是当我尝试使用它时，我得到了这个:

我在网上能找到的都是这个问题的老例子，以及关于让 MySQL-python 在 OSX 上工作有多么困难的大量提示。如果有人可以提供帮助，我将不胜感激!!
最佳答案
我最终开始工作的唯一(公认的笨拙)解决方案是在应用 this patch 之后使用 MySQL-python-1.2.2。 ，根据此处 ( http://www.mangoorange.com/2008/08/01/installing-python-mysqldb-122-on-mac-os-x/ ) 和此处 ( http://flo.nigsch.com/?p=62 ) 的建议拼凑而成。抱歉缺少链接，但我没有足够的代表点数来发布多个链接。
关于python - 在 OSX : symbol not found _mysql_affected_rows 上使用 MySQLdb 时出现问题，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/3423289/
