Question

注意：这篇文章在底部的EDITs部分有几个发展。

我无法弄清楚为什么我的小程序会抛出错误。

似乎很多其他人都有同样的问题。我刚读了this article，基本上说安装gtk是不可能的。当然不是这样......

让我们弄清楚这一点。

我认为控制台读数中最相关的一行（下面打印）是GtkWarning: Screen for GtkWindow not set; you must always set a screen for a GtkWindow before using the window。我已经用谷歌搜索了这个，但我无法弄清楚如何设置屏幕......＆＃34;在使用窗口之前

which python给/opt/local/bin/python，这就是我想要的，我想，因为我正在使用通过macports安装的库。

我已按照this帖子中提供的程序进行操作，因此我确信我正在运行py27-pygtk。

#!/opt/local/bin/python2.7
import gtk, os

window = gtk.Window()
window.connect("destroy", gtk.main_quit)

image = gtk.Image()
window.add(image)
image.set_from_file(os.path.join("data", "image1.jpg"))

window.show_all()
gtk.main()

这是控制台读数：

$ python imageHello.py

编辑：我在某个地方读过（一旦发现它就会发布链接）你需要一些叫做x11的东西来使用gtk。所以我刚跑sudo port -v install xorg-server。这没有用。

EDIT2：刚刚下载了xquartz from their website。但是，我认为这是关键，我重启了我的电脑。现在我能够让我的程序正常运行。但是，我仍然收到以下警告。我不知道这意味着什么。有什么想法吗？

$ python imageHello.py

** (process:312): WARNING **: Trying to register gtype 'GMountMountFlags' as enum when in fact it is of type 'GFlags'

你如何为python安装gtk（没有很多错误）
