我是 Emacs 的新手。
我已经使用M-x package-install然后安装了 ensime ensime。
通过在 Emacs 中执行ensime命令并给出项目路径（gen-ensime在其上执行），我得到以下错误：
Debugger entered--Lisp error: (error "check that sbt is on your PATH and that your config is compatible with http://github.com/ensime/ensime-server/wiki/Example-Configuration-File [(wrong-type-argument stringp nil)]")
signal(error ("check that sbt is on your PATH and that your config is compatible with http://github.com/ensime/ensime-server/wiki/Example-Configuration-File [(wrong-type-argument stringp nil)]"))
error("check that sbt is on your PATH and that your config is compatible with http://github.com/ensime/ensime-server/wiki/Example-Configuration-File [(wrong-type-argument stringp nil)]")
(condition-case ex (ensime--1) ((quote error) (error (format "check that sbt is on your PATH and that your config is compatible with %s [%s]" "http://github.com/ensime/ensime-server/wiki/Example-Configuration-File" ex))))
ensime()
call-interactively(ensime record nil)
command-execute(ensime record)
execute-extended-command(nil "ensime")
call-interactively(execute-extended-command nil nil)
SBT 0.13.6 添加到路径中，当我键入ensime-sbt-command并C-j在 Lisp-Interaction 窗口中显示 SBT 路径时。
我的项目 SBT 版本是 0.13.5，Scala 2.11.1，Play 2.3.3，ensime-sbt 0.1.5-SNAPSHOT。
Emacs 版本是 24，ensime 版本是 20141101.910。
