我在 OS 10.8.5 上运行 Python 2.7.2

尝试使用 pymssql，但出现以下错误：

  File "time_reporting.py", line 32, in <module>
    import pymssql
  File "/Users/xx/.virtualenvs/oracle/lib/python2.7/site-packages/pymssql.py", line 30, in <module>
    import _mssql, types, string, time, datetime, warnings
ImportError: No module named _mssql

我尝试使用 pip 和 brew 安装 mssql，结果却被告知没有该名称的包。文档似乎没有涵盖安装。

编辑：

当我尝试时，pip install pymssql我得到：

所以我尝试brew install freetds并得到：

Warning: freetds-0.91 already installed, it's just not linked

这至少是有道理的，但我不知道如何解决它。

编辑：我已经链接了它，所以brew install freetds给出了它已经安装的消息，但pip install pymssql仍然给出了上述错误消息。

编辑： 

export CFLAGS=-Qunused-arguments
export CPPFLAGS=-Qunused-arguments

pip uninstall MySQL-python
brew uninstall mysql
brew install mysql --universal
pip install MySQL-python

现在给了我错误：

Traceback (most recent call last):
  File "time_reporting.py", line 34, in <module>
    import pymssql
ImportError: dlopen(/Users/xxx/.virtualenvs/oracle/lib/python2.7/site-packages/pymssql.so, 2): Symbol not found: _dbversion

  Expected in: flat namespace
 in /Users/xxx/.virtualenvs/oracle/lib/python2.7/site-packages/pymssql.so

我以前有过并修复过，但我不记得我做了什么。

编辑：

好的，我已经重新安装了 32 位 oracle 并强制 Python 运行 32 位版本（我想。我真的不知道最后一句话是什么意思，但我认为我已经正确地遵循了说明）。

无论如何，这是我现在的错误信息：

  File "time_reporting.py", line 31, in <module>
    import cx_Oracle

以root身份运行这些：

export CFLAGS=-Qunused-arguments
export CPPFLAGS=-Qunused-arguments

然后不得不这样做：

pip uninstall MySQL-python
brew uninstall mysql
brew install mysql --universal
pip install MySQL-python

不确定它是否会成功，但至少是一条新的错误消息。

尝试使用ldconfig。

取自手册页：

ldconfig创建必要的链接并缓存到在命令行指定的目录、文件 /etc/ld.so.conf 和受信任的目录（/lib 和 /usr/lib）中找到的最新共享库。
