如何修复“错误类型参数：listp”，尝试使用流浪汉访问远程文件时出错？ [英] How do I fix a "Wrong Type Argument: listp," error when trying to access remote file using tramp?

问题描述

我以通常的方式无法访问远程文件：

I am unable to access remote files in my usual way:

Cx Cf
[server]：[path]文件]

并抛出此错误：
错误类型参数：listp，[[server] ：[路径] [文件]

我甚至不知道如何进一步调试。

I'm not even sure how to debug this further.

任何帮助都不胜感激。

尝试调试输出时： / p>

推荐答案

检查什么命令 Cx Cf 被绑定（使用 Ch k ）。是否是标准绑定 find-file ？ （这听起来不像。）

Check what command C-x C-f is bound to (use C-h k). Is it the standard binding find-file? (It doesn't sound like it.)

如果没有，请检查其交互式规格。该命令期待收到列表作为参数，而是接收（看起来像）一个字符串。

If not, check its interactive spec. The command is expecting to receive a list as argument, and it is instead receiving (what looks like) a string.

这是交互式 spec of find-file ：

This is the interactive spec of find-file:

(interactive
 (find-file-read-args "Find file: " (confirm-nonexistent-file-or-buffer)))

如果您的 Cx Cf 命令的交互式有一个非字符串作为其参数，那么你可以 Mx调试输入THE-FUNCTION ，其中 THE-FUNCTION 是调用参数的函数（ find-file-read-args ，在 find-file ）或包装该参数以调用调试器：

If the interactive spec of your C-x C-f command, like this one, has a non-string as its argument, then you can either M-x debug-on-entry THE-FUNCTION, where THE-FUNCTION is the function called for the argument (find-file-read-args, in the case of find-file), or wrap that argument so that the debugger is invoked:

(progn (debug) (WHATEVER-WAS-THERE-BEFORE))

无论哪种方式，调试器将打开阅读文件名的交互式部分，您可以通过调试器查看出现什么问题。

Either way, the debugger will open for the interactive part of reading the file name, and you can walk through the debugger to see what goes wrong.

但是，您可以通过检查代码 - 交互式规范来解决问题。您的命令的参数（无论是什么）预计将是一个列表，但它是一个字符串。

But probably you can figure out the problem just by inspecting the code -- the interactive spec. The argument to your command (whatever it is) is expected to be a list, but it is a string.

我将首先看看本地文件名称会发生​​什么。你也收到一个错误？

I would start by seeing what happens with a local file name. Do you get an error for that too?

另一件事我注意到，错误报告了一个额外的 [在你说你输入的内容前面。这也应该提供一个线索。你认为阅读的内容不是它所读的。

Another thing I notice is that the error reports an extra [, in front of what you say you typed as input. That should provide a clue too. What you think it is reading is not what it has read.
