custom-save-all: Cannot save customizations; init file was not fully loaded

请帮忙

Answer 1

如果我们查看 custom-save-all 的来源在 cus-edit.el 中，我们发现:

(defun custom-save-all ()
  "Save all customizations in `custom-file'."
  (when (and (null custom-file) init-file-had-error)
    (error "Cannot save customizations; init file was not fully loaded"))

因此，在加载 init 文件时会出现错误。尝试使用 --debug-init 启动 emacs启用 Emacs Lisp 调试器以帮助您查找 init 文件中的错误的选项。
