I'm trying to install the cx_Oracle for Python 2.6, but it is failing. I don't know enough about C or MS Vis. Studio's compiler to even approach fixing it myself.
This is what is output on the command line:
C:pydevcx_Oracle-5.0.1>C:python26python setup.py install
running install

error: command '"C:Program FilesMicrosoft Visual Studio 9.0VCBINcl.exe"' failed with exit status 2
Does anyone have any idea how to fix this?
(I also may have an issue with that cl.exe file, I think I remember seeing this as a problem somewhere else, but I have four Windows machines which could have had issue there.).
----------------------------- EDIT -----------------------------
The reason I do not use the pre-compiled installer is because when I try to run the module I get the following:
Python 2.6.3 (r263rc1:75186, Oct 2 2009, 20:40:30) [MSC v.1500 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import cx_Oracle
Traceback (most recent call last):
File "", line 1, in
ImportError: DLL load failed: The specified module could not be found.
I assume that means that it has not been properly installed. If someone can tell me what I did wrong here, that would also be a perfectly acceptable answer.
----------------------------- EDIT2 -----------------------------
I have retrieved all files from Oracle's Basic Client version 11.1.0.7. I have not tried installing a more substantial client. I am downloading one now.
%ORACLE_HOME%=C:Oracleinstantclient #The directory where the above files have been extracted.
More information
- The current directory for the cx_Oracle's setup.py is C:pydevcx_Oracle-5.0.1
- The version of Python is 2.6.3
- The current directory for Python is C:Python26 -- to access python 2.6 -> type py26 on the command line and it will map to C:python26python
