安装cx_Oracle-5.1.3时:
执行$ python setup.py build
能正确构建,但安装时出现以下问题:
sudo python setup.py install
Traceback (most recent call last):
File "setup.py", line 135, in
raiseDistutilsSetupError("cannot locate an Oracle software " \
distutils.errors.DistutilsSetupError: cannot locate an Oraclesoftware installation
原因分析:
sudo env | grep ORACLE_HOME没有输出,说明root用户的oracle环境没有配置,故出现以上错误
参考:

解决办法:
su -
vi /root/.bashrc
追加以下内容:
#oracle 11g installclient env
export ORACLE_HOME=/opt/ora11g/instantclient_11_2
export TNS_ADMIN=$ORACLE_HOME/network/admin
export NLS_LANG='simplified chinese_china'.UTF8
export PATH=$PATH:$ORACLE_HOME/bin
source /root/.bashrc
进入cx_Oracle-5.1.3源代码路径,执行python setup.py install
安装成功
登出root
