Python raw_input 在使用 py2app 创建应用后导致 EOFError

Question

我写了一个小脚本，可以帮助我解决拼字游戏和单词拼图的问题。在Mac OS X的终端上运行得很好。我想把这个脚本分享给我的朋友们，做成一个独立的Mac应用程序。所以我用了py2app来实现这个目标，但当我双击应用程序时，它崩溃了。控制台显示了以下错误信息：

1/17/11 2:13:51 PM [0x0-0x4a44a4].org.pythonmac.unspecified.warp[9875] Enter letters: Traceback (most recent call last):

这是实际的脚本：

import string

word = raw_input("Enter letters: ")
dict = open('dict.txt')
wordmap = {}
for c in string.lowercase:
    wordmap[c] = 0

for c in word:
    if c in wordmap:
        wordmap[c] = wordmap[c]+1

for line in dict:
    line = line.strip()
    if len(line) >= 3:
        linemap = {}
        for c in string.lowercase:
            linemap[c] = 0
        for c in line:
            if c in linemap:
                linemap[c] = linemap[c]+1
        match = True
        for c in linemap:
            if linemap[c] > wordmap[c]:
                match = False
        if match is True:
            print line

我该怎么解决这个错误呢？

用 py2app 把 Python 程序打包成应用时，应用里没有可以输入内容的终端窗口。所以你需要提供一些更高级的方式来输入和输出，比如使用 Python 的 Tkinter 模块。如果你的脚本可以在终端运行，而你想把它做成一个可以点击的应用，那么把它打包成 Automater 或 AppleScript 应用，来启动一个 Terminal 会更简单。
