java.lang.UnsatisfiedLinkError：java.library.path 中没有 jhdf5答案

【问题标题】：java.lang.UnsatisfiedLinkError: no jhdf5 in java.library.pathjava.lang.UnsatisfiedLinkError：java.library.path 中没有 jhdf5

【问题描述】：

我在运行保存和加载 h5 文件的 Scala Saddle 1.3.4 应用程序时遇到上述错误。

我已经尝试过配置以下（Win64）但没有成功：

-Djava.library.path=C:\Dev\Tools\HDF5\1.10.0\lib\
-Djava.library.path=C:\Dev\Tools\HDF5\1.10.0\lib\jarhdf5-1.10.0.jar
-Dnative.libpath.jhdf5=C:\Dev\Tools\HDF5\1.10.0\lib\hdf5_java.dll
-Dnative.libpath=C:\Dev\Tools\HDF5\1.10.0\lib\

以及其他一些替代方案，但我仍然得到堆栈跟踪：

【问题讨论】：

我通过下载 HDFView 然后在路径 -Dncsa.hdf.hdf5lib.H5.hdf5lib=C:\HDFView\2.13.0\lib\jhdf5.dll 中添加以下内容解决了这个问题
你在哪里添加这个？
对于那些尝试使用 HDFView 的人，我通过在路径环境变量中添加“/HDFViewApp-3.1.2-win10_64-vs16\HDFView\app\bin”来解决这个问题，然后重新启动 cmd

标签： java scala hdf5 saddle

【解决方案1】：

我在 Windows 操作系统上启动二进制文件时遇到了同样的问题。启动HDFView.exe 后会弹出一个命令窗口，然后再次关闭。

通过 CLI 启动它后，我看到了您提到的错误：

java.lang.UnsatisfiedLinkError: no jhdf5 in java.library.path

我用上面的@kaladin anwser 解决了这个问题：我将路径<path to app>/HDFViewApp-3.1.2-win10_64-vs16\HDFView\app\bin 添加到 PATH 系统环境变量中。保存后重启EXE文件，直接按预期运行！
