1) 首先通过命令安装cx_Oracle
(1)pip installcx_Oracle
(2)也可在pycharm里面安装,File->Default Setting ->Project Interpreter->添加cx_Oracle->Install package;
如果安装失败,点击Manage Repositories :更换仓库地址为:http://pypi.douban.com/simple/
(3)去官网下载源码包:cx_Oracle-5.2.1.tar.gz;
/2014th7cj/d/file/p/20161205/hzktkrgmnj2.1
2)去oracle官网下载mac版的64bit的client basic 和client sdk
http://www.oracle.com/technetwork/topics/intel-macsoft-096467.html
3)编译安装:
sudo su #切换到root用户
mkdir /Users/guanguan/oracle #创建oracle文件
mv /Users/guanguan/Downloads/instantclient-* /Users/guanguan/oracle #将下载的两个Oracle包放到/Users/guanguan/oracle目录下
cd /Users/guanguan/oracle 进入oracle文件中
unzip instantclient-basic-macos.64-12.1.0.4.0.zip #解压
unzip instantclient-sdk-macos.64-12.1.0.4.0.zip #解压
cd instantclient_12_1/sdk
unzip ottclasses.zip
cd ..
cp -R ./sdk/* .
cp -R ./sdk/include .
ln -s libocci.dylib.12.1 libocci.dylib
ln -s libclntsh.dylib.12.1 libclntsh.dylib
4)更改环境变量:
vi ~/.bash_profile
export ORACLE_HOME=/Users/guanguan/oracle/instantclient_12_1
export DYLD_LIBRARY_PATH=$ORACLE_HOME
export LD_LIBRARY_PATH=$ORACLE_HOME
然后输入source ~/.bash_profile 或者 . ~/.bash_profile使环境变量生效
5)测试环境变量是否生效
echo $ORACLE_HOME
/Users/guanguan/oracle/instantclient_12_1
6)然后解压安装cx_Oracle:
tar -zxvf cx_Oracle-5.2.1.tar.gz
cd cx_Oracle-5.2.1
python setup.py build
python setup.py install
7)测试cx_Oracle安装是否成功
python
import cx_Oracle
#运行结果结果:
➜ ~ python Python 2.7.10 (default, Oct 23 2015, 19:19:21) [GCC 4.2.1 Compatible Apple LLVM 7.0.0 (clang-700.0.59.5)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import cx_Oracle >>>
或者 python -c "import cx_Oracle"
➜ ~ python -c "import cx_Oracle" ➜ ~
此时说明已经安装成功啦~
