如何使用 WPHP 和 Python Paste

Question

有人向我建议回答对我的问题如何使用 Python 的 CGIHTTPRequestHandler 作为 PHP 的开发服务器我尝试一下WPHP。

我试过了：

import wphp

my_php_app = wphp.PHPApp('/path/to/php-files/')

from paste import httpserver

httpserver.serve(my_php_app)

但无论我在浏览器中请求什么，我都会得到：

Exception happened during processing of request from ('127.0.0.1', 49397)
Traceback (most recent call last):
