我試圖從命令行運行BehaviorSpace的實驗，但BehaviorSpace不加載擴展。有a similar question，bur我既不能理解答案也不能評論，所以我會在這裏解釋我的問題。Headless BehaviorSpace無法加載擴展
我修改fire.nlogo模式，通過GUI從guide添加一個名爲「experiment1」隨機試驗和複製粘貼：
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 -
這工作。
然後，添加
"extensions[csv]"
作爲模型中的第一行並運行相同的指令。這就是我得到：

如果我重複的步驟，使用的NetLogo 5.3.1-64，我得到一個不同的錯誤開始
java.lang.IllegalStateException: Can't find extension: csv/csv.jar
我試過位擴展，而不是CSV，但沒有運氣。值得注意的是，如果我從GUI開始實驗，那麼這個實驗就可以運行我使用 Ubuntu 16.10和 java-1.8.0-openjdk-amd64。
