java - 如何修复 netlogo headless (headless)模式下的 JNI 错误？

Question

我阅读了 NetLogo 5.3.1 的所有说明，但是当我运行时:

java -Xmx1024m -Dfile.encoding=UTF-8 -cp NetLogo.jar org.nlogo.headless.Main --model "C:\thesis\NetLogo\headless\NetLogo-Headless\Fire.nlogo" --experiment a --table -

我有以下错误。

我在不同的帖子中读到了有关 JNI 错误的信息，但我什么也没发现。

当我在 NetLogo 安装的应用程序目录(NetLogo.jar 所在的位置)中运行代码时，它终于解决了。
