当我在本地（Windows）安装ibm_db模块时，它工作正常。但是当我试图在我的Gitlab项目（Linux）中安装ibm_db模块时，它失败了。首先，我必须手动下载db2驱动程序，将其解压缩到一个文件夹并将“IBM_DB_HOME”变量设置到该文件夹。我这样做了，但现在我得到了另一个错误。下面是日志。

我手动下载的库来自以下URL

https://github.com/ibmdb/db2drivers/raw/main/clidriver/linuxx64_odbc_cli.tar.gz

现在我不确信是错误的。
谢谢你给我指明了正确的方向。

查看错误消息/usr/bin/ld: cannot find -ldb2，这意味着链接器无法定位您的Db2库。
请查看readme页面上的说明，特别是在构建之前，导出环境变量LD_LIBRARY_PATH，其中包含一个条目，以包含包含您的Db2库的目录：
(for在linux export LD_LIBRARY_PATH=$IBM_DB_HOME/lib:$LD_LIBRARY_PATH上的示例）
