WSL2中导入ssdeep提示找不到fuzzy_64.dll但文件存在的问题

问题场景 #

在WSL2环境下执行import ssdeep时触发OSError，提示找不到fuzzy_64.dll，但通过ls命令确认该文件实际存在。

错误日志 #

Exception has occurred: OSError
/usr/local/lib/python3.10/dist-packages/ssdeep_windows_32_64-0.0.1-py3.10.egg/ssdeep/bin\fuzzy_64.dll: cannot open shared object file: No such file or directory

文件验证输出 #

ls '/usr/local/lib/python3.10/dist-packages/ssdeep_windows_32_64-0.0.1-py3.10.egg/ssdeep/bin'
fuzzy.dll  fuzzy_64.dll

原因解析 #

• 路径分隔符不兼容：错误信息中的路径使用了Windows风格的反斜杠\，而WSL2基于Linux系统，仅识别正斜杠/。该ssdeep库为Windows平台开发，硬编码了Windows路径格式，导致Linux环境下无法正确解析路径。
• 库文件格式不兼容：fuzzy_64.dll是Windows专属的动态链接库，WSL2的Linux系统无法直接加载这类文件。Linux系统需要的是.so格式的共享库，而非Windows的.dll文件。
