尝试使用 celery 和 celery beat 启动我的开发服务器时，突然出现以下错误。有一天这个东西可以工作，第二天就不行了，我没有改变任何可以解释这一点的东西。我使用工头和 Procfile.dev 启动我的服务器，如下所示：
档案：
web: python manage.py runserver
celeryd: python manage.py celeryd -E -B --loglevel=INFO --concurrency=3
worker: python manage.py celerycam
命令：
foreman start -f Procfile.dev
就像我说的，这从来没有给出任何错误。堆栈跟踪如下：

我安装的软件包的版本：
Django==1.4.1
celery==3.0.8
pytz==2012c
我曾尝试重新安装 pytz，但这并没有帮助。
任何建议如何解决这个问题？

我已经尝试过 Burhan Khalid 的回答，这确实修复了 IOError，但是抛出了一个新错误。我尝试了两个地方来粘贴 zoneinfo 数据，它们导致了不同的错误，您可以在下面找到：
当像建议的那样粘贴到 usr/share/zoneinfo/ 中时，我得到了这个：

因此，提供的 zoneinfo 数据似乎不正确/不完整。我从哪里获得正确的数据？

我将 Burhan Khalid 的答案标记为答案，即使对我来说它不起作用。我这样做是因为我确定我做错了什么并且答案是正确的。我如何解决这个问题只是简单地将 zoneinfo 数据从另一台 macbook 复制粘贴到这个。
