通过Python执行外部软件

Question

我有一个通过终端正常执行的Java程序。但是，当我尝试通过另一个python代码执行它时，更具体地说是通过操作系统（）或子流程运行（）函数，我得到以下错误：

Exception in thread "main" java.lang.UnsatisfiedLinkError: com.slytechs.library.NativeLibrary.dlopen(Ljava/lang/String;)J

TCP/IP Features were extracted to: /CICFlowMeter/bin/

为了执行java程序，我使用以下命令：

   subprocess.run( ["/home/user/PycharmProjects/untitled/CICFlowMeter/bin/cfm", "/home/user/PycharmProjects/untitled/CICFlowMeter/bin/", "/home/user/PycharmProjects/untitled/CICFlowMeter/bin/"])

java程序名为cfm，输入两个参数，特别是两个目录的路径。cfm是一种流量计：

https://github.com/ISCX/CICFlowMeter

根据上面GitHub页面提供的指令，为了执行cicflometer，我只需要安装libpcap dev库。你知道吗

有什么想法吗？你知道吗
