我的操作系统是 Debian Squeeze。这是vim版本:

VIM - Vi IMproved 7.2(2008 年 8 月 9 日,2010 年 7 月 12 日 02:29:33 编译)

我阅读了关于http://kovisoft.bitbucket.org/tutorial.html的教程并尝试为 MIT-Scheme 启动 REPL。不幸的是,我没有开始。

当我按下“,c”时,它启动了一个终端窗口加载 mit-scheme。vim 的 REPL 缓冲区中没有显示任何内容。终端显示一些错误:

Listening on port: 4005
;netcat: "4005: inverse host lookup failed: Unknown host"
;To continue, call RESTART with an option number:
; (RESTART 1) => Return to read-eval-print level 1.

2 error> 

我阅读了源代码并修复了一些错误(关于 netcat 的参数和其他内容),这是 diff 文件:

我重试了,但出现了一些新问题。

;The object #f, passed as the second argument to integer-add, is not the correct type.
;To continue, call RESTART with an option number:

; (RESTART 3) => Return to SLIME top-level.

这是日志文件(swank.log)

这是一个已知问题。我的 git repo 中有一个Slimv的补丁版本,它修复了这个问题以及其他一些问题。

请注意,我使用 Slimv 是很久以前的事了,所以我不记得我做了什么确切的更改。我只在 OS X 上测试过这个,所以 YMMV。
