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。

我在不同的文章中读到有关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所在的目录）中运行代码时，它终于解决了。

如何在netlogo无头模式下修复JNI错误？
