cygwin上的python导入cx_Oracle错误

Question

我尝试从 pypi 源安装 cx_Oracle，因为在 cygwin 中没有可用的端口。我确实按照 http://permalink.gmane.org/gmane.comp.python.db.cx-oracle/2492 中的建议进行了一些更改并修改了我的 setup.py。但是，我仍然收到以下错误:-

$ python
Python 2.7.3 (default, Dec 18 2012, 13:50:09)
[GCC 4.5.3] on cygwin
Type "help", "copyright", "credits" or "license" for more information.

如果有人可以帮我解决这个问题？

TIA。

Answer 1

通过如下指定 instantclient 的路径来修复此问题:

$ export PATH=$PATH:/cygdrive/d/Tools/instantclient_11_2

(其他，可能重要的东西):

$ echo $LD_LIBRARY_PATH
/cygdrive/d/Tools/instantclient_11_2
$ echo $ORACLE_HOME
/cygdrive/d/Tools/instantclient_11_2

现在，我得到:-
