运行保存和加载 h5 文件的 Scala Saddle 1.3.4 应用程序时出现上述错误。

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：

在 Windows 操作系统上启动二进制文件时，我遇到了同样的问题。启动后HDFView.exe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：我将路径添加<path to app>/HDFViewApp-3.1.2-win10_64-vs16\HDFView\app\bin到PATH系统环境变量。保存后，我重新启动了EXE文件，它直接按预期工作了！
