helm我的 Emacs 初始化文件和helm-swoop在我的 Emacs 初始化文件中有以下配置：
(use-package helm
:demand t
:diminish helm-mode
:init
(progn
(require 'helm-config)
(setq helm-candidate-number-limit 100)
(setq helm-idle-delay 0.0
helm-input-idle-delay 0.01
helm-yas-display-key-on-candidate t
helm-quick-update t
helm-M-x-requires-pattern nil)
(helm-mode)
)
:bind (
("C-h a" . helm-apropos)
("C-x C-b" . helm-buffers-list)
("C-x b" . helm-buffers-list)
("M-y" . helm-show-kill-ring)
("M-x" . helm-M-x)
("C-x C-f" . helm-find-files)
("C-c h o" . helm-occur)
("C-c h r" . helm-register)
("C-c h b" . helm-resume)
)
:config
(setq helm-command-prefix-key "C-c h")
(setq helm-autoresize-min-height 25)
(setq helm-autoresize-max-height 25)
(setq helm-split-window-in-side-p t
helm-move-to-line-cycle-in-source t
helm-ff-search-library-in-sexp t

helm-ff-file-name-history-use-recentf t)
(setq helm-buffer-max-length nil)
(helm-mode 1)
(helm-autoresize-mode 1)
(define-key helm-map (kbd "<tab>") 'helm-execute-persistent-action)
(define-key helm-map (kbd "C-i") 'helm-execute-persistent-action)
(define-key helm-map (kbd "C-z") 'helm-select-action)
:ensure helm)
(use-package helm-swoop
:ensure t
:bind (("C-c h s" . helm-multi-swoop))
:init
(bind-key "M-i" 'helm-swoop-from-isearch isearch-mode-map)
:config
(define-key helm-swoop-map (kbd "M-i") 'helm-multi-swoop-current-mode-from-helm-swoop)
)
helm-swoop在无数的在线示例中，我已经看到在该部分中配置了两者的模式映射绑定config:，我似乎无法将其放入helm-swoop-map，init:因为我得到一个 void symbol name 错误，但我必须放入isearch-mode-map绑定，init否则绑定不会在启动时设置。为什么会这样？
