python-3.x - Hello World 失败

Question

我刚刚在我的 Windows 7 机器上安装了 python 3.2.1(32 位)和 cherrypy 3.2.1(CherryPy-3.2.1.win32-py3.exe)并尝试了 hello world 示例(通过PyScripter)，但它在引擎总线启动消息后挂起。

如果我尝试通过 python.exe 启动它，我会得到以下日志:

C:\Program Files (x86)\Python32>python hello.py

我错过了什么？

代码:

import cherrypy

class HelloWorld:
    def index(self):
        return "Hello world"
    index.exposed = True

cherrypy.quickstart(HelloWorld())

编辑:奖金信息:我尝试了各种方法来补救这种情况，但没有结果。安装 64 位版本的 python 没有帮助，因为 cherrypy 不支持 64 位(除非我弄错了)。我试过重新安装 python 和 cherrypy 包，我试过停用所有其他可能阻止它的东西 (IIS)。一切都无济于事:-(

EDIT2:第二个好处 - 如果我用 python 2.7.2 安装它一切正常，所以似乎它只是 3.x 的问题(我也试过 3.0.1 - 同样的问题)

Answer 1

我遇到了两个错误:

1 - 在启动脚本之前打开您的浏览器，这样您就不会遇到任何问题。

2 - 如果您使用个人防火墙或处理 HTTP 保护的防病毒软件，请确保他没有保护 8080 端口，例如 ESET Antivirus 不会让您使用 8080，CherryPy 会说该端口不可用.
