Question

我有Ubuntu 16.04（在Docker上），并希望使用Python连接到远程Oracle数据库。为此 - 使用cx_oracle模块。

尝试：

pip install cx_oracle

- ＆GT;抱怨libaio1和libaio-dev遗失..

apt-get install libaio1 libaio-dev

- ＆GT;再次抱怨：
cx_Oracle.DatabaseError: DPI-1047: 64-bit Oracle Client library cannot be loaded: "libclntsh.so: cannot open shared object file: No such file or directory"

是否有一个命令可以在Ubuntu 16.04上正确安装cx_Oracle（或者需要手动执行所有操作 - >尝试自动执行所有步骤......）

感谢。

找不到（还）简单的方法，但这就是我所做的：

这对我来说非常适用于 Ubuntu 16 ：

从Oracle下载（＆＃39; instantclient-basic-linux.x64-12.2.0.1.0.zip＆＃39;以及＆＃39; instantclient-sdk-linux.x64-12.2.0.1.0.zip＆＃39;）网站，然后做以下脚本（你可以一块一块地做，我作为一个ROOT）：

apt-get install -y python-dev build-essential libaio1
mkdir -p /opt/ora/
cd /opt/ora/

## Now put 2 ZIP files:
# ('instantclient-basic-linux.x64-12.2.0.1.0.zip' and 'instantclient-sdk-linux.x64-12.2.0.1.0.zip') 
# into /opt/ora/ and unzip them -> both will be unzipped into 1 directory: /opt/ora/instantclient_12_2 

rm -rf /etc/profile.d/oracle.sh
echo "export ORACLE_HOME=/opt/ora/instantclient_12_2"  >> /etc/profile.d/oracle.sh
echo "export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME"  >> /etc/profile.d/oracle.sh
chmod 777 /etc/profile.d/oracle.sh
source /etc/profile.d/oracle.sh
env | grep -i ora  # This will check current ENVIRONMENT settings for Oracle


rm -rf /etc/ld.so.conf.d/oracle.conf
echo "/opt/ora/instantclient_12_2" >> /etc/ld.so.conf.d/oracle.conf
ldconfig
cd $ORACLE_HOME  
ls -lrth libclntsh*   # This will show which version of 'libclntsh' you have... --> needed for following line:

ln -s libclntsh.so.12.1 libclntsh.so

pip install cx_Oracle   # Maybe not needed but I did it anyway (only pip install cx_Oracle without above steps did not work for me...)

现在python脚本已经可以使用＆＃39; cx_Oracle＆＃39;。

Ubuntu 16.04 - （适用于Python的Oracle模块） - 如何安装＆＃39; cx_Oracle＆＃39;模块简单方法？
