如何在WIndows上使用Cython编译Pyparsing？

Question

我试图在我的Windows机器上编译Pyparsing但是遇到以下错误:

python setup.py build_ext --inplace
running build_ext
cythoning pyparsing.pyx to pyparsing.c

Error compiling Cython file:
------------------------------------------------------------
...
       If C{include} is set to true, the matched expression is also parsed (the
skipped text
       and matched expression are returned as a 2-element list).  The C{ignore}
       argument is used to define grammars (typically quoted strings and comment
s) that
       might contain false matches.

    def __init__( self, other, include=False, ignore=None, failOn=None ):
                              ^

        self.mayReturnEmpty = True
        self.mayIndexError = False
        self.includeMatch = include
                           ^

我使用Microsoft Visual C++ 2008 Express版进行了编译,使用的Pyparsing模块是最新版本.请问,有谁知道如何使这项工作？

先生,我按照你的说法做了,但仍然有编译时警告:

    python setup.py build_ext --inplace
    running build_ext
    cythoning pyparsing.pyx to pyparsing.c
    warning: pyparsing.pyx:413:8: Unreachable code

    \Desktop\pyparsing\pyparsing.pyd;2

警告实际上在第4行:警告:pyparsing.pyx:413:8:无法访问的代码.然后我将该行改为:

    def __getattr__( self, name ):
            if True: #name not in self.__slots__:
                if name in self.__tokdict:
                    if name not in self.__accumNames:
                        return self.__tokdict[name][-1][0]
                    else:
                        return ParseResults([ v[0] for v in self.__tokdict[name] ])
                else:
                    return ""
            else:
                return None

然后重新编译它.我注意到的一件事是,即使我发出警告和编辑,它们都成功编译,但是当我尝试使用以下代码进行测试时:

    from pyparsing import Word, alphas
    greet = Word(alphas) + ',' + Word(alphas) + '!'
    greeting = greet.parseString('Hello, World!')
    print greeting

我收到以下错误:

    Traceback (most recent call last):
      File "C:\nwaomachux\build_pyparsing\checkout.py", line 1, in 
        from pyparsing import Word, alphas
      File "pyparsing.pyx", line 3414, in init pyparsing (pyparsing.c:100064)
    AttributeError: 'builtin_function_or_method' object has no attribute 'ANY_VALUE'

我会进一步修改文件并发送给你检查它,但我只有几个小时的Pyparsing,所以我还没有掌握完整的源代码.

我不知道将withAttribute.ANY_VALUE = object()移动到def withAttribute(args,*attrDict)的开头是什么效果: function表示.请问,它有什么问题？谢谢.
