Emacs中的DBus错误

6

我正在尝试在OS X上使用notify.el，但每次都会出现以下错误：

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

运行emacs --debug-init命令，输出如下：

Debugger entered--Lisp error: (void-variable dbus-message-type-method-call)

有人知道如何处理它吗？

附：我已经通过homebrew安装了dbus。

你需要使用支持DBus的Emacs才能实际使用DBus。在OS X上，这相当不寻常，我无法想象你为什么要在Emacs中使用DBus支持，因为在OS X上没有其他东西使用DBus。

但如果你只是想要通知，你不需要DBus。事实上，在OS X上，DBus不会给你通知。

要在OS X上使用notify.el进行通知，你需要Growl。也就是说，你必须购买AppStore中的Growl，或者自己构建它，并另外安装http://growl.info/downloads中的Growlnotifier。
