Headless BehaviorSpace无法加载扩展

Question

我正在尝试从命令行运行BehaviorSpace实验，但是BehaviorSpace没有加载扩展。有一个a similar question，但是我既不能理解答案，也不能理解评论，所以我在这里解释我的问题。

我修改了fire.nlogo模型，通过图形用户界面添加了一个名为"experiment1“的随机实验，并从guide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 -

这是可行的。

然后我补充说

"extensions[csv]" 

作为模型中的第一行，并运行完全相同的命令。这是我得到的：

如果我使用Netlogo 5.3.1-64重复此过程，则会得到另一个错误，以

java.lang.IllegalStateException: Can't find extension: csv/csv.jar

我尝试了位图扩展，而不是CSV，但没有成功。值得注意的是，如果我从GUI启动，这个实验就能正常工作。

我使用Ubuntu 16.10和java-1.8.0-openjdk-amd64。

Answer 1

我也遇到过类似的问题。

对我来说，当我将文件夹extensions从NetLogo/app/复制到NetLogo文件夹( netlogo-headless.sh通常所在的位置)时，这个问题就解决了。
