Cygwin:unittest2上的easy_install导致SyntaxError

Question

我正在尝试为Cygwin安装unittest2。我想我错过了一些相对简单的东西，但我不知道它是什么

$ easy_install --version
distribute 0.6.34
$ python --version
Python 3.2.5

当我尝试easy_install unittest2时，我得到以下输出：

$ easy_install -U unittest2

怎么回事？

尝试easy_install unittest2py3k(https://pypi.python.org/pypi/unittest2py3k)。您收到的错误是由于Python 3中(http://docs.pythonsprints.com/python3_porting/py-porting.html#exceptions)
