Indy-vdr Python包装器可导入但无法调用功能问题求助

我按照Indy-vdr官方文档使用其Python包装器，文档说明Python包装器位于wrappers/python/indy_vdr，要让包装器找到共享库，需将共享库放置在/usr/local/lib这类系统共享库目录。我已将wrapper/python/下的内容放入系统Python路径中的/usr/local/lib/python3.8/dist-packages目录，执行python3.8 -c "import sys; print(sys.path)"可看到该目录在路径中，且目录下包含demo、indy_vdr等文件。

但我能成功执行import indy_vdr，调用功能（如运行demo或执行python3 -c "import indy_vdr; print(indy_vdr.version())"）时却报错，提示加载indy_vdr库失败，具体报错信息如下：

Demo运行报错 #

简单命令报错 #
