使用 py2app 创建应用程序后 Python raw_input 导致 EOFError

Question

我编写了一个小脚本，可以帮助我解决拼字游戏和单词扭曲问题。当我从 Mac OS X 终端运行它时它工作正常。我想将脚本作为独立的 Mac 应用程序与我的朋友分享。因此我为此使用了 py2app，但是当我双击它时应用程序崩溃了。控制台显示以下错误消息：

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

我怎样才能摆脱错误？

由py2app 包装为应用程序的 Python 程序没有用于输入输入的终端窗口。您需要提供一些更高级的输入输入和输出输出方式，例如使用 Python 的 Tkinter 模块。如果您的脚本从终端运行并且您想要制作一个可点击的应用程序，那么将其打包为一个启动Terminal 会话的Automater 或AppleScript 应用程序可能会更简单。
