emacs中的dbus错误

Question

我尝试在 OS X 上使用 notify.el，但每次都会出现下一个错误：

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

emacs --debug-init 给出下一个输出：

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")

有人知道怎么处理吗？

P。 S. 我已经通过自制软件安装了 dbus。

您需要构建支持 DBus 的 Emacs 才能真正使用 DBus。在 OS X 上，这很不寻常，而且我看不出你想在 Emacs 中使用 DBus 支持做什么，因为在 OS X 上没有其他东西使用 DBus。

不过，如果您只是在收到通知，则不需要 DBus。事实上，DBus 不会在 OS X 上给你通知。

对于带有notify.el 的 OS X 通知，您需要 Growl。即，你必须在 AppStore 中购买 Growl，或者自己构建，另外从http://growl.info/downloads 安装 Growlnotifier。
