python - 在 Mac OS Lion 上安装 oursql 成功，但在 python 中导入失败。 **为什么？**

Question

我按照安装说明在 Mac OS X 上安装 oursql。因为

sudo pip install oursql

告诉我，它找不到 mysql_config 我(使用 locate mysql_config 找到它并)告诉它在哪里可以找到它

sudo MYSQL_CONFIG=/usr/local/mysql-5.5.14-osx10.6-x86_64/bin/mysql_config pip install oursql

出于可读性原因，我在底部添加了终端输出。之后我在终端中启动了 python(在 Mac OS Lion 上它现在是 python 2.7，...)并做了

>>> import oursql

但是 python 一直告诉我:

>>> import oursql
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: dlopen(/Library/Python/2.7/site-packages/oursql.so, 2): Library not loaded: libmysqlclient.18.dylib
  Referenced from: /Library/Python/2.7/site-packages/oursql.so
  Reason: image not found

我错过了什么？有什么建议吗？
