Question

当我将http://localhost:8888/cgi-bin/peoplecgi.py?action=Fetch&key=sue（sue是搁置中的有效密钥）发送到下面的cgi脚本时，我得到以下内容（我也使用Python 3.3进行OSX）。出了什么问题？

127.0.0.1 - - [04/Feb/2014 10:38:41] "GET /cgi-bin/peoplecgi.py?action=Fetch&key=sue HTTP/1.1" 200 -
Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/3.3/lib/python3.3/http/server.py", line 1131, in run_cgi
    os.execve(scriptfile, args, env)

我正在研究O'Reilly的Programming Python第4版。这个问题基于示例1-33。

weberver.py：

import os, sys
from http.server import HTTPServer, CGIHTTPRequestHandler

webdir = '/Users/rich/Google Drive/Code/Python/PP4E/Preview/'
port = 8888

os.chdir(webdir)
srvraddr = ("", port)
srvrobj = HTTPServer(srvraddr, CGIHTTPRequestHandler)
srvrobj.serve_forever()

peoplecgi.py

import cgi, shelve, sys, os
shelvename = 'class-shelve'

replyhtml="""

rowhtml = '<tr><th>%s<td><input type=text name=%s value="%%(%s)s">\n'
rowshtml = ''
for fieldname in fieldnames:
    rowshtml += (rowhtml % ((fieldname,) * 3))

replyhtml = replyhtml.replace('$ROWS$', rowshtml)

def htmlize(adict):
    new = adict.copy()
    for field in fieldnames:
        value = new[field]

在这种情况下的解决方案是我使用错误版本的Python来运行脚本。 osx 10.9中的默认值是Python 2.7.5。我想用python 3.3运行它，因此我的解决方案只是用适当的版本执行它：#!/usr/local/bin/python3
