Python 2.5上的select模块的问题 [英] Problems on select module on Python 2.5

问题描述

我在Python 2.5中有一个监听beantalk队列的应用程序.除了我最近购买的MacBook Pro，它在到目前为止我测试过的所有机器上都可以正常工作.

I have an application in Python 2.5 that listens to a beanstalk queue. It works fine on all machines I tested so far, except from my newly acquired MacBook Pro.

在那台计算机上，当我尝试运行它时，出现此错误:

On that computer, when I try to run it I get this error:

Traceback (most recent call last):
  File "jobs.py", line 181, in <module>
    Jobs().start()
  File "jobs.py", line 154, in start
    self.jobQueue = Queue()
  File "src/utils/queue.py", line 16, in __init__
    self.connection = serverconn.ServerConn(self.server, self.port)
  File "src/beanstalk/serverconn.py", line 25, in __init__
    self.poller = select.poll()
AttributeError: 'module' object has no attribute 'poll'

serverconn.py具有以下导入:

The serverconn.py has the following imports:

import socket, select

当我尝试从命令行运行它时，它也会失败:

And when I try to run it from command line, it fails as well:

Python 2.5.1 (r251:54863, Jul 23 2008, 11:00:16)

>>> import select
>>> select.poll()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'poll'

您对可能发生的事情有任何了解吗?

Do you have any idea on what can be happening?

PS:即使我非常确定这不是源问题，但是如果您需要失败源的某些背景知识，也可以在[ http://pastie.org/399342](此粘贴).

PS: Even though I am pretty confident it's not a source problem, if you need some background on the source that's failing, it's available at [http://pastie.org/399342](this pastie).

已更新:因为我得到的第一个答案推测Mac OS上是否支持select.poll()，但我也有iMac，并且操作系统版本完全相同，因此工作正常:

Updated: since the first answer I got speculates whether select.poll() is or not supported on Mac OS, but I have an iMac too and with the exact same OS version and it works fine:

推荐答案

使用 MacPorts 版本的python在您的MBP上.

use the MacPorts version of python on your MBP.

Mac OS X支持此功能.苹果股票Leopard python 2.5.1没有.

Mac OS X supports this. Apple stock Leopard python 2.5.1 does not.

如果尚未下载并安装MacPorts，则需要.仅供参考，我发现 Porticus 是围绕MacPorts的出色GUI.

you will want to download and install MacPorts if you have not already. FYI, I find Porticus to be an excellent GUI around MacPorts.

这是股票Leopard python与最新的MacPorts python2.5的比较...

here is a comparison of stock Leopard python vs. latest MacPorts python2.5...

Apple的豹纹python(python 2.5.1)- select.poll()损坏

Leopard python from Apple (python 2.5.1) - select.poll() broken

Macports(python 2.5.4)- select.poll()可以使用！

Macports (python 2.5.4) - select.poll() works!
