我通过搜索找到了类似的问题。然而，以前的解决方案似乎是以Windows为中心，而不是以Linux为中心。

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". See https://oracle.github.io/odpi/doc/installation.html#linux for help
Sudo’d用户-(导入cx_Oracle后(
Traceback (most recent call last):

ImportError: libnnz11.so: cannot open shared object file: No such file or directory
我已经按照错误消息中找到的链接的说明进行了操作，但没有任何帮助。https://oracle.github.io/odpi/doc/installation.html#linux
我确实验证了各个部分的架构：
Oracle即时客户端：instantclient-basic-linux.x64-11.2.0.4.0.zip
libaio:
libaio-devel-0.3.109-17.15.x86_64
libaio1-0.3.109-17.15.x86_64
Python 3:
Python 3.4.6 (default, Mar 01 2017, 16:52:22) [GCC] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import platform
>>> platform.architecture()
('64bit', 'ELF')
>>>
在启动应用程序之前设置库搜索路径。我建议使用ldconfig，如ODPI-C安装链接和实际的cx_Oracle安装文档所示。
使用Instant Client时，不要设置ORACLE_HOME或ORACLE_BASE。为什么要在应用程序中设置PATH？？
我还建议使用Instant Client 18.3，它可以连接到Oracle Database 11.2以后的版本。
