cx_Oracle: distutils.errors.DistutilsSetupError: cannot locate Oracle include files

I need install cx_Oracle for Python 2.5 on Linux (Linux 2.6.18-371.1.2.el5 i686). I have installed Oracle client 10.2.0.4.

I have tried following: 1. Download cx_Oracle tar.gz from http://sourceforge.net/projects/cx-oracle/files/. I don't know which of listed version are suitable for python 2.5 and Oracle client 10.2.0.4, so try cx_Oracle-5.1.tar.gz. Unpacked tar, go to unpacked folder and run python setup.py install. I got error:

Traceback (most recent call last):
File "setup.py", line 187, in <module>
raise DistutilsSetupError("cannot locate Oracle include files")
distutils.errors.DistutilsSetupError: cannot locate Oracle include files

In .bash_profile I have setted oracle path:

export ORACLE_HOME=/usr/oracle/10.2.0.4/client
export PATH=$ORACLE_HOME/bin
export LD_LIBRARY_PATH=$ORACLE_HOME/lib

How fix such error, maybe I need another version of cx_Oracle tar?

  1. Run pip install cx_Oracle. Got error:

Downloading/unpacking cx-Oracle

Cannot fetch index base URL https://pypi.python.org/simple/
Could not find any downloads that satisfy the requirement cx-Oracle
No distributions at all found for cx-Oracle

Could someone advise me right solution?

Update After suggestion in response I got following error:

When you run setup.py it will check for any of these folders on your ORACLE_HOME.

possibleIncludeDirs = ["rdbms/demo", "rdbms/public", "network/public",
        "sdk/include"]

Also the instant client sometimes places the include files, such as oci.h, in /usr/include/oracle//client, if there is no 'include' directory under ORACLE_HOME create a symbolic link to it.

sudo ln -s /usr/include/oracle/11.2/client $ORACLE_HOME/include

Looks like you're missing the Client SDK

Make sure you install the instant client sdk for you OS.

  1. Install oracle_client_basic

    oracle-instantclient11.2-basic-11.2.0.4.0-1.x86_64.rpm
    
  2. Using pip install

    python -m pip install cx_Oracle
    
  3. Adding ldconfig

    1. Find your client location, for example: /u01/app/oracle/product/11.2.0/client_1/lib
    2. vi /etc/ld.so.conf.d/oracle.conf

      Add this location into it:

      /u01/app/oracle/product/11.2.0/client_1/lib
      
    3. ldconfig
  4. import cx_oracle
