Question

在emacs中编辑.emacs.el时，我运行了Alt + X eval-buffer命令。我的操作系统是Windows。当我重新启动emacs时，它会显示以下警告：

警告（初始化）：加载时发生错误   `... / emacs.el＆＃39;：

错误：用于Unicode转义的非十六进制数字

为确保正常操作，您应该调查并删除   初始化文件中的错误原因。用。启动Emacs   `--debug-INIT＆＃39;用于查看完整错误回溯的选项。

.emacs.el是：

;;Aspell install failed

我如何解决它？

Answer 1

问题在于以下几点：

(setq backup-directory-alist
    `((".*" . ,"D:\Unix-Tmp")))
(setq auto-save-file-name-transforms
    `((".*" ,"D:\Unix-Tmp" t)))

\U引入了unicode转义...并且必须跟随十六进制数字。

你实际上想要的是一个字面反斜杠字符，所以你需要逃避它;即

(setq backup-directory-alist
    `((".*" . ,"D:\\Unix-Tmp")))
(setq auto-save-file-name-transforms
    `((".*" ,"D:\\Unix-Tmp" t)))

参考：http://www.gnu.org/software/emacs/manual/html_node/elisp/Basic-Char-Syntax.html#Basic-Char-Syntax

但是，这似乎会导致另一个问题。一个更好的解决方案是做@Stefan建议的。使用＆＃34; /＆＃34;而不是＆＃34; \＆＃34;作为路径名分隔符。（甚至可以在Windows上工作......）

Answer 2

始终在Emacs中使用转发斜杠而不是向后斜杠作为文件名。 Windows通常更喜欢反斜杠，但除少数例外情况外，Windows实际上也接受正斜杠。

Answer 3

错误是由D：\ Unix-Tmp引起的，\ U引入了unicode转义，如Stephen所说。

但是当我改为：

(setq backup-directory-alist
    `((".*" . ,"D:\\Unix-Tmp")))
(setq auto-save-file-name-transforms
    `((".*" ,"D:\\Unix-Tmp" t)))

它将引发另一个：

正在加载d：/git_root_tfs/WorkStation/Unix-Home/.recentf ...完成清洁 upf list ... done（0已删除）有关GNU Emacs的信息和GNU系统，类型C-h C-a。 make-auto-save-file-name：无效使用`\＆＃39;在替换文本

最后我将路径更改为D：\ Tmp-Unix，它可以正常工作。

(setq backup-directory-alist
    `((".*" . ,"D:\Tmp-Unix")))
(setq auto-save-file-name-transforms
    `((".*" ,"D:\Tmp-Unix" t)))

Windows中的Emacs将正斜杠（/）视为反斜杠（\）。指定任何类型的路径时，应始终使用正斜杠。 Emacs将正确解释它们。这允许您将转义序列使用控制到预期效果的时间。

C:/Users/username/AppData/Roaming/.emacs是Emacs中完全有效的路径/文件名。
