我正在尝试从命令行使用 BehaviorSpace 进行实验，但 BehaviorSpace 没有加载扩展。有一个类似的问题，但是我既不能理解答案也不能发表评论，所以我将在这里解释我的问题。
我修改了 fire.nlogo 模型，通过 GUI 添加了一个名为“experiment1”的随机实验，并从指南中复制粘贴：
java -Xmx1024m -Dfile.encoding=UTF-8 -cp ~/Desktop/netlogo-6.0-M6-64/app/NetLogo.jar\
org.nlogo.headless.Main \
--model "~/Desktop/netlogo-6.0-M6-64/app/models/Sample Models/Earth Science/Fire.nlogo" Fire.nlogo" \
--experiment experiment1 \
--table -
这行得通。
然后我添加
"extensions[csv]"
作为模型中的第一行并运行完全相同的命令。这就是我得到的：

如果我用 Netlogo 5.3.1-64 重复这个过程，我会得到一个不同的错误，从
java.lang.IllegalStateException: Can't find extension: csv/csv.jar
我尝试了位图扩展而不是 CSV，但没有运气。值得注意的是，如果我从 GUI 启动实验，它就会起作用。
我使用 Ubuntu 16.10 和 java-1.8.0-openjdk-amd64。
