我一直将RNetLogo与NetLogo 5.2.1一起使用时没有遇到麻烦.现在，我正在使用NetLogo 5.3，但出现此错误:

I have been using RNetLogo with NetLogo 5.2.1 without troubles. Now I am using NetLogo 5.3 and I get this error:

推荐答案

将行nl.path <- "/Applications/NetLogo 5.3/"更改为nl.path <- "/Applications/NetLogo 5.3/app" NetLogo更改了其目录结构； netlogo jar文件现在位于"app"子目录中.

Change your line nl.path <- "/Applications/NetLogo 5.3/" to nl.path <- "/Applications/NetLogo 5.3/app" NetLogo has changed its directory structure; the netlogo jar file is now in an 'app' subdirectory.

您可能还需要检查在RNetLogo安装过程中设置的环境变量.

You may also need to check the environment variables that you set up as part of the RNetLogo installation.
