这可以解决Ubuntu吗?
您需要同时安装cx_Oracle和Oracle Client。
cx_Oracle可以在这里找到。
可以在此处找到适当的Oracle客户端。
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):
1 | 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。
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? 您可以在Python shell会话中连接到Oracle数据库吗?
1 2 3 | import cx_Oracle conn = cx_Oracle.connect('/') # user/password@dsn cursor = conn.cursor() |
如果这不会引发异常,则表示已成功连接。
尝试easy_install cx_Oracle,它将从源代码编译cx_Oracle模块
