mu4e如何更改查找目錄來自mu4e-action-view-as-pdf功能

我想在mu4e中以pdf函數的形式工作，我猜測問題是可執行文件的查找目錄msg2pdf 。從函數定義我看到mu4e如何更改查找目錄來自mu4e-action-view-as-pdf功能

(defvar mu4e-msg2pdf "/usr/bin/msg2pdf" "Path to the msg2pdf toy.") 

(defun mu4e-action-view-as-pdf (msg) 
    "Convert the message to pdf, then show it. 
Works for the message view." 
    (unless (file-executable-p mu4e-msg2pdf) 
    (mu4e-error "msg2pdf not found; please set `mu4e-msg2pdf'")) 
    (let* ((pdf 
     (shell-command-to-string 
     (concat mu4e-msg2pdf " " 
      (shell-quote-argument (mu4e-message-field msg :path)) 
      " 2> /dev/null"))) 
    (pdf (and pdf (> (length pdf) 5) 
     (substring pdf 0 -1)))) ;; chop \n 
    (unless (and pdf (file-exists-p pdf)) 
     (mu4e-warn "Failed to create PDF file")) 
    (find-file pdf)))

，我改變了(defvar mu4e-msg2pdf "/usr/bin/msg2pdf" "Path to the msg2pdf toy.") 其中msg2pdf是相匹配的路徑。的問題是，從調試器我看到

Debugger entered--returning value: nil 
    file-executable-p("/build/buildd/maildir-utils-0.9.9.5/toys/msg2pdf/msg2pdf") 
* #[(msg) "\305!\204\n ...... 
* mu4e-action-view-as-pdf((..... 
    mu4e-view-action() 
    call-interactively(mu4e-view-action nil nil)

的查找路徑是不是我指定的。由於我試圖用不同的方式修改它，顯然mu4e忽略了我，有沒有人知道我該如何設置正確的查找路徑？

您可以通過添加設置變量mu4e-msg2pf可執行msg2pdf的路徑下，以你的init文件

(setq mu4e-msg2pdf "/path/to/msg2pdf")
