Emacs警告加载"... /.emacs.el"时发生错误:

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`... /.emacs.el'时发生错误:

错误:用于Unicode转义的非十六进制数字

为确保正常运行,您应该调查并删除初始化文件中的错误原因.使用`--debug-init'选项启动Emacs以查看完整的错误回溯.

.emacs.el是:

;;Aspell install failed

我怎么解决它？

Answer 1

问题是这些问题:

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

在\U引入了Unicode转义......并且必须后跟十六进制数字.

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)))

UPDATE

但是,这似乎会导致另一个问题.更好的解决方案是做@Stefan建议的事情.使用"/"代替"\"作为路径名分隔符.(它应该在Windows上工作......)
