emacs中用于plink（putty）的新comint mod：Symbol的函数定义无效

问题描述

我想对plink（putty）使用一种新的comint模式，我将代码放在init.el中，但是如果执行Mx run-plink，我会遇到以下错误：

i want to use a new comint mode for plink(putty), i put the code in init.el, but if M-x run-plink, i got below error:

let *：Symbol的函数定义无效：comint-check-proc

  (setq plink-buffer "*Plink*")     
  (let* ((plink-program plink-file-path) (buffer (comint-check-proc "Plink")))

推荐答案

您尚未加载库 comint 。在Emacs知道 comint-check-proc 之前，需要这样做。

You have not loaded library comint. You need to do that before Emacs can know about comint-check-proc.

添加（需要'comint），位于您的init文件中，或者位于 run-plink 开头附近-在尝试使用<$之前c $ c> comint-check-proc 。

Add a (require 'comint), either in your init file or near the beginning of run-plink - somewhere before it tries to use comint-check-proc.
