Question

每当我尝试运行python manage.py syncdb之类的命令时，我都会收到以下错误：

Traceback (most recent call last):

这可以在Ubuntu上解析吗？

Answer 1

您需要同时安装cx_Oracle和Oracle客户端。

cx_Oracle可以是found here。

适当的Oracle客户端可以是found here。

在启动应用程序之前，还需要设置LD_LIBRARY_PATH变量。通常可以这样做（例如）：

export LD_LIBRARY_PATH=/usr/lib/oracle/11.2/client64/lib

现在您应该能够通过cx_Oracle错误消息。

Answer 2

首先要做的事情 - 这实际上是一个Django问题，还是只是一个cx_Oracle问题？是否正确安装了cx_Oracle？你能在Python shell会话中连接到Oracle数据库吗？

import cx_Oracle
conn = cx_Oracle.connect('/') # user/password@dsn
cursor = conn.cursor()

如果这不会引发异常，则表示您已成功连接。

Answer 3

尝试easy_install cx_Oracle，它将从源代码

编译cx_Oracle模块

无法在Ubuntu上使用Django连接到Oracle数据库
