我在Python 2.5中有一个监听beanstalk队列的应用程序.它在我测试的所有机器上都能正常工作,除了我新购买的MacBook Pro.

在那台计算机上,当我尝试运行它时,我收到此错误:

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:

import socket, select

当我尝试从命令行运行它时,它也会失败:

Python 2.5.1 (r251:54863, Jul 23 2008, 11:00:16) 
[GCC 4.0.1 (Apple Inc. build 5465)] on darwin
Type "help", "copyright", "credits" or "license" for more information. …

我正在尝试使用sha-512来计算hmac.

Perl代码:

use Digest::SHA qw(hmac_sha512_hex);

$key = "\x0b"x20;
$data = "Hi There";

$hash = hmac_sha512_hex($data, $key);
print "$hash\n";

并给出正确的哈希值

Python版本:

import hashlib, hmac

print hmac.new("\x0b"*20, "Hi There", hashlib.sha512).hexdigest()

它给出了错误的哈希值

任何想法为什么Python版本给我错误的哈希？
