【问题描述】:
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
Cython 抛出此错误:
running build_ext
cythoning TrieNode.pyx to TrieNode.c
Error compiling Cython file:
------------------------------------------------------------
...
nil = object() # used to distinguish from None
class TrieNode(object):
__slots__ = ['char', 'output', 'fail', 'children']
def __init__(self, char):
^

TrieNode.pyx:7:24: Empty declarator

TrieNode.c(1) : fatal error C1189: #error : Do not use this file, it is the result of a failed Cython compilation.
error: command 'cl.exe' failed with exit status 2
我的 setup.py 目前看起来像这样:
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"])]
)
我看到了一个示例,其中 Python 类被编译为 Cython 文件而没有问题,但这个似乎不起作用。谁能告诉我我错过了什么?
【问题讨论】:
-
@eryksun:这很奇怪。我正在使用相同的版本。 :( 你也在使用 64 位机器吗?
-
@eryksun:摇滚明星!我将
char更改为_char并正确编译。您能否将其发布为答案,以便我接受?
