非ASCII有效负载错误。我在
python2.7
中没有遇到这个错误。发生什么事了

这是由于Python-3.4.0b3中的错误造成的。此错误已被修复2014-02-07 18:30（）

您可以使用
Python-3.4.0rc1
，也可以通过在
Python 3.4.0b3
上复制
email
包来修复它，如中所确认

我刚刚在squeeze上用Python-3.4.0rc1对其进行了测试，该软件包已成功安装：

$ pip install django-floppyforms==1.1
Downloading/unpacking django-floppyforms==1.1
  Downloading django_floppyforms-1.1-py33-none-any.whl (51kB): 51kB downloaded
Installing collected packages: django-floppyforms
Successfully installed django-floppyforms

从
tox
运行针对Python3.4.0b2的测试时，我在运行
pip
时遇到了类似的错误。如果我手动创建并激活virtualenv，并使用其
pip3.4
，则不会发生这种情况。问题中的包是否与Python 3兼容（它彻底改变了底层unicode字符串）？
