我正在尝试使用Cython编译以下.pyx
文件:
import collections
nil = object() # used to distinguish from None
class TrieNode(object):
__slots__ = ['char', 'output', 'fail', 'children']
def __init__(self, char):
self.char = char
self.output = nil
self.fail = nil
self.children = {}
def __repr__(self):
if self.output is not nil:
return "<TrieNode '%s' '%s'>" % (self.char, self.output)
else:
return "<TrieNode '%s'>" % self.char
而 Cython 抛出了这个错误:
running build_ext
cythoning TrieNode.pyx to TrieNode.c
Error compiling Cython file:

nil = object() # used to distinguish from None
class TrieNode(object):

我的 setup.py 目前看起来是这样的:
from distutils.core import setup
from distutils.extension import Extension
from Cython.Distutils import build_ext
setup(
cmdclass = {'build_ext': build_ext},
ext_modules = [Extension("TrieNode", ["TrieNode.pyx"])]
)
我看过一个例子,其中一个Python类被编译成了Cython文件而没有出现问题,但是这个似乎不起作用。有人可以告诉我我错过了什么吗?
