emacs中的dbus錯誤

Question

我正在嘗試在OS X上使用notify.el，但是每次都會得到下一個錯誤：

Symbol's value as variable is void: dbus-message-type-method-call

emacs --debug-init提供下一個輸出：

Debugger entered--Lisp error: (void-variable dbus-message-type-method-call)
  dbus-call-method(:session "org.freedesktop.Notifications" "/org/freedesktop/DBus" "org.freedesktop.DBus.Peer" "Ping")

有人知道如何處理嗎？

PS我已經通過自制軟件安裝了dbus。

您需要使用DBus支持構建Emacs才能真正使用DBus。 在OS X上，這是很不常見的事情，並且鑒於沒有其他東西在OS X上使用DBus，因此我看不到想要在Emacs中使用DBus支持的功能。

但是，如果您只是在收到通知，則不需要DBus。 實際上，DBus不會在OS X上給您通知。

要在OS X上使用notify.el進行通知，您需要Growl。 即，您必須在AppStore中購買Growl，或者自己構建它，並另外從http://growl.info/downloads安裝Growlnotifier。
