从Python连接到Oracle数据库

Question

Trying to connect to Oracle database from Python using cx-oracle. I followed steps mentioned in this link: https://gist.github.com/thom-nic/6011715

I am running Python 2.7.8. on Yosemite(10.10.2).After I unzip instant client into this path on my machine: /Users/ayada/Library/Share/oracle which is set to ORACLE_HOME and have set both DYLD_LIBRARY_PATH, LD_LIBRARY_PATH to ORACLE_HOME. I use Pip(env ARCHFLAGS="-arch $ARCH" pip install cx_Oracle) to install cx_oracle but encountering following error: distutils.errors.DistutilsSetupError:

Oracle home (/Users/ayada/Library/Share/oracle) does not refer to an 9i, 10g, 11g or 12c installation.

Cleaning up... Command python setup.py egg_info failed with error code 1 in /private/var/folders/22/78xh65wd3xq232p4zd18l8800013hw/T/pip_build_ayada/cx-Oracle Storing debug log for failure in /Users/ayada/.pip/pip.log

To give some context, I don't have Oracle database installed on my machine but I am trying to connect to a remote server.

I am relatively newbie to working on Mac and doing these kind of setups. Please advice.

Have you done as kevindalias advised in the comments section of the link you pasted?

Seems like Oracle made a change to the basic zip since this was posted, so to anyone else who arrives here:

ln -s libclntsh.dylib.11.2 libclntsh.dylib ln -s libocci.dylib.11.2 libocci.dylib

should be...

ln -s libclntsh.dylib.11.1 libclntsh.dylib ln -s libocci.dylib.11.1 libocci.dylib

You'll see both 11.1 files when you unpack the zips, and the links need to point to them. With this tweak, I was able to install cx_Oracle 5.1.2 on OS X 10.8.5 using 64-bit versions of Oracle Instant Client 11.2 and Python 2.7.6. Good luck.

Also I don't know about Mac, but in RHEL, my ORACLE_HOME is different to LD_LIBRARY_PATH:

LD_LIBRARY_PATH=$ORACLE_HOME/lib ORACLE_HOME=/usr/lib/oracle/12.1/client64
