Question

我遇到错误“ cx_Oracle.DatabaseError：DPI-1047：无法找到64位Oracle客户端库：“ libclntsh.so：无法打开共享库文件：没有这样的文件或目录。”有关的信息，请参见https://oracle.github.io/odpi/doc/installation.html#linux帮助”

我看到了https://oracle.github.io/odpi/doc/installation.html#oracle-instant-client-zip和How to fix: cx_Oracle.DatabaseError: DPI-1047: Cannot locate a 64-bit Oracle Client library - Python

我始终在Windows上工作，并且仅在Linux系统上学习。我需要这个问题的帮助。从python连接到Oracle：

import cx_Oracle
con = cx_Oracle.connect('<USER>/<PASSWORD>@<HOST>:<PORT>/<SID>')

我从没有连接过Linux。这是第一次。

Answer 1

问题解决了。也许会很高兴：下载rpm（oracle-instantclient12.2-basic，oracle-instantclient12.2-devel，oracle-instantclient12.2-devel）。

当然，只需要oracle-instantclient12.2

sudo apt-get install oracle-instantclient12.2-basic-12.2.0.*

只需添加到PATH：

user@postgresql:~$export LD_LIBRARY_PATH=/usr/lib/oracle/12.1/client64/lib/${LD_LIBRARY_PATH:+:$LD_LIBRARY_PATH}
user@postgresql:~$sudo ldconfig
user@postgresql:~$ sudo nano  /etc/profile.d/oracle.sh && sudo chmod o+r /etc/profile.d/oracle.sh
export PATH=$PATH:/usr/lib/oracle/12.2/client64/bin

Linux。连接到Oracle。 cx_Oracle.DatabaseError：DPI-1047无法找到64位Oracle Client库：“ libclntsh.so
