linux环境下cx_Oracle的“ImportError: No module named cx_Oracle”

环境：redhat AS5.0 + python2.7.2 + oracle instant client + cx_oracle

oracle instant client10.2.4.1 (linux)

http://www.oracle.com/technetwork/database/features/instant-client/index-097480.html

需要用到的三个包的下载地址如下：

http://download.oracle.com/otn/linux/instantclient/10204/oracle-instantclient-sqlplus-10.2.0.4-1.i386.rpm

http://download.oracle.com/otn/linux/instantclient/10204/oracle-instantclient-basic-10.2.0.4-1.i386.rpm

http://download.oracle.com/otn/linux/instantclient/10204/oracle-instantclient-devel-10.2.0.4-1.i386.rpm

python2.7

http://cx-oracle.sourceforge.net/

下载的源码包是：cx_Oracle-5.0.4.tar.gz

环境变量：

export ORACLE_HOME=/usr/lib/oracle/10.2.0.4/client
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME/lib

遇到的问题：

在软件安装完毕，环境变量配置成功后，报错：“ImportError: No module named cx_Oracle”

解决：cx oracle官方下载源码包，编译后在安装，搞定了。

http://cx-oracle.sourceforge.net/，找到对应版本的“Source Code only”，下载后按照redme指示，

python setup.py build
python setup.py install

再次python import cx_Oracle，不报错了

[root@test ~]# python

测试代码

>>> import os

>>> import cx_Oracle

>>> os.environ['NLS_LANG']=”SIMPLIFIED CHINESE_CHINA.ZHS16GBK” #这句话是为了让oracle database中读出来的gbk编码中文正常显示而设设置的语言环境

>>> dsn = cx_Oracle.makedsn(“192.168.1.10″, “1521″, “db”)

>>> conn = cx_Oracle.connect(username, password, dsn)

>>> db_cursor = conn.cursor()
