Python | cx_Oracle | DPI-1047报错处理（Win\Mac\Linux)

测试代码

import cx_Oracle# 建立与 Oracle 数据库的连接
connection = cx_Oracle.connect("{login}/{passwd}@{IP}:{PORT}/{Service Name}")# 创建游标
cursor = connection.cursor()# 执行 SQL 查询
cursor.execute("SELECT table_name FROM user_tables")# 获取查询结果
result = cursor.fetchall()# 处理查询结果
for row in result:# 处理每一行数据print(row)# 提交事务（如果需要）
connection.commit()# 关闭游标和数据库连接
cursor.close()
connection.close()

报错信息

Traceback (most recent call last):File "~/test_oracle.py", line 4, in <module>connection = cx_Oracle.connect("xxx/xxx@xxx:xxx/xxx")
cx_Oracle.DatabaseError: DPI-1047: Cannot locate a 64-bit Oracle Client library: "dlopen(libclntsh.dylib, 0x0001): tried: 'libclntsh.dylib' (no such file), '/System/Volumes/Preboot/Cryptexes/OSlibclntsh.dylib' (no such file), '/Users/py373/lib/libclntsh.dylib' (no such file), '/System/Volumes/Preboot/Cryptexes/OS/Users/py373/lib/libclntsh.dylib' (no such file), '/Users/py373/lib/libclntsh.dylib' (no such file), '/System/Volumes/Preboot/Cryptexes/OS/Users/py373/lib/libclntsh.dylib' (no such file), '/Users/anaconda".

解决步骤

1. 报错信息的最后一点已经提到了解决方案参考：点击跳转
2. 以MacOS为例（Win和Linux可参考1中文档进行操作），下载DMG文件：

   cd $HOME/Downloads
   curl -O https://download.oracle.com/otn_software/mac/instantclient/198000/instantclient-basic-macos.x64-19.8.0.0.0dbru.dmg
   hdiutil mount instantclient-basic-macos.x64-19.8.0.0.0dbru.dmg
   /Volumes/instantclient-basic-macos.x64-19.8.0.0.0dbru/install_ic.sh
   hdiutil unmount /Volumes/instantclient-basic-macos.x64-19.8.0.0.0dbru
   

3. 将文件内容全部放到python的lib库中
   
4. 再次执行Python脚本（问题解决）
