线程"main"中的异常java.lang.UnsatisfiedLinkError:java.library.path中没有jep

本文介绍了线程"main"中的异常java.lang.UnsatisfiedLinkError:java.library.path中没有jep的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

下载jep后，我有'libjep.so'文件，并且还在〜./bashrc 中设置了环境变量 LD_LIBRARY_PATH ，如下所示:

I have 'libjep.so' file after downloading jep and I also had set the environmental variable LD_LIBRARY_PATH in ~./bashrc as shown below:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib/python2.7/dist-packages/jep/libjep.so

以及在运行时

System.load("/usr/local/lib/python2.7/dist-packages/jep/libjep.so");

但是当我的代码中包含以下一行时，

But when I have the follwing line in my code,

Jep jep = new Jep();

它显示以下错误:

Exception in thread "main" java.lang.UnsatisfiedLinkError: no jep in java.library.path
    at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1867)
    at java.lang.Runtime.loadLibrary0(Runtime.java:870)
    at java.lang.System.loadLibrary(System.java:1122)
    at jep.Jep$TopInterpreter$1.run(Jep.java:118)
    at java.lang.Thread.run(Thread.java:745)

谢谢

推荐答案

您需要将LD_LIBRARY_PATH设置为包含您的库的目录，而不是这样的库本身

You need to set the LD_LIBRARY_PATH to the directory containing your library, and not your library itself like this

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib/python2.7/dist-packages/jep/

您还可以在启动Java应用程序时尝试将此参数添加到java命令中，以便Java可以找到该库

You can also try adding this argument to the java command when you start your java application so java can find the library

-Djava.library.path=/usr/local/lib/python2.7/dist-packages/jep/
