如何在El Capitan上安装cx_Oracle

本文介绍了如何在El Capitan上安装cx_Oracle的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

据我了解，与SIP相关的一些更改使安装此操作变得困难.

As I understand it, there was some change related to SIP that makes installing this difficult.

这些页面具有背景和安装建议. http://sourceforge.net/p/cx-oracle/mailman/message/34534872/， http://stefanoapostolico.com/2015/10/08/install_cx_oracle_with_sip_enabled.html

These pages have the background and advice to install. http://sourceforge.net/p/cx-oracle/mailman/message/34534872/, http://stefanoapostolico.com/2015/10/08/install_cx_oracle_with_sip_enabled.html

将所有这些放在一起，这是将其安装到我的virtualenv中的最好的镜头，但是，还是不好.

Putting all this together, here was my best shot at installing it to my virtualenv but alas, still no good.

我得到的错误是:

Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: dlopen(/Users/me/sx_direct_env/lib/python2.7/site-packages/cx_Oracle.so, 2): Library not loaded: /b/227/rdbms/lib/libclntsh.dylib.10.1

这是我所有的安装步骤:

Here are all of my install steps:

$ cd oracle

推荐答案

我认为我已修复它.基本上我上面发布的步骤中的所有内容都是正确的.

I think I fixed it. Basically everything in my steps posted above were correct.

但是我最终在安装pip时使用了它，以确保它能够拉下新副本并进行重建(并可能获得更高的版本?)

But I ended up using this for the pip install to make sure it pulls down a new copy and rebuilds (and maybe gets a later version??)

$ pip install --no-cache-dir --allow-external --allow-unverified cx_oracle

然后，我能够毫无问题地导入cx_oracle，但在连接到外部服务器时出现错误'ORA-21561:OID生成失败'".

I was then able to import cx_oracle without issues but I was getting an error "'ORA-21561: OID generation failed'" when connecting to the external server.

然后，我遵循了此处的说明，并在/etc/hosts文件中添加了一行带有我的主机名的文件，现在一切正常.

Then I followed the instructions here and added a line with my host name to the /etc/hosts file and it all works now.

例如，在/etc/hosts的末尾添加这样的一行

e.g., added a line like this at the end of /etc/hosts

127.0.0.1本地主机我的主机名

127.0.0.1 localhost my-host-name
