python 引用外部 pyd, dll, so 文件

作者: 刘一二 发布时间: 2023年9月8日 浏览: 24

pyd 文件通过包名可以直接引入

如果 pyd 文件又调用了 dll 或 so 动态链接库,windows 下和 linux 下对动态链接库的引用需要特殊配置


windows 下

需要将 dll 文件所大的目录配置到 系统 PATH 中 



linux 下

ImportError: cannot open shared object file: No such file or directory



可修改 ~/.bashrc 或 /etc/profile,  加入以下内容


如果是 venv 部署的,可可以编辑 [venv目录名]/bin/activate



In Linux, the environment variable LD_LIBRARY_PATH is a colon-separated set of directories where libraries should be searched for first, before the standard set of directories; this is useful when debugging a new library or using a nonstandard library for special purposes. The environment variable LD_PRELOAD lists shared libraries with functions that override the standard set, just as /etc/ does. These are implemented by the loader /lib/ I should note that, while LD_LIBRARY_PATH works on many Unix-like systems, it doesn't work on all; for example, this functionality is available on HP-UX but as the environment variable SHLIB_PATH, and on AIX this functionality is through the variable LIBPATH (with the same syntax, a colon-separated list).
