Cython AttributeError:“模块"对象没有属性“声明" [英] Cython AttributeError: 'module' object has no attribute 'declare'

问题描述

编译.pyx文件工作正常，但突然在键入时开始出现错误

Compiling .pyx files was working fine but suddenly it started raising error when I type:

python setup.py build_ext --inplace

我得到了错误:

c:\Python27\cython\helloworld>python setup.py build_ext --inplace
running build_ext
cythoning hello.pyx to hello.c
Traceback (most recent call last):
  File "setup.py", line 8, in <module>

AttributeError: 'module' object has no attribute 'declare'

我尝试在简单的.pyx文件helloworld上运行它:

I tried running it on a simple .pyx file helloworld:

def say_hello_to(name):
    print "Hello %s!" %name

与setup.py:

from distutils.core import setup
from distutils.extension import Extension
from Cython.Distutils import build_ext

setup(
  name = 'Hello world app',
  cmdclass = {'build_ext': build_ext},
  ext_modules = [Extension("hello", ["hello.pyx"])]
)

它已经运行了好几次，有些变化了，但是当我搜索并搜索该问题时，我找不到任何信息.我使用的是最新版本的Cython Python 2.7 64位，并且使用Windows SDK C/C ++编译器来编译文件，并通过运行以下命令准备环境:

It already worked several times, something has changed but as I Googled and searched the issue I couldn't find any information. I'm using Python 2.7 64 bits, latest version of Cython and to compile the file I use Windows SDK C/C++ compiler and prepare the environment by running:

C:\Program Files\Microsoft SDKs\Windows\v7.0>set DISTUTILS_USE_SDK=1
C:\Program Files\Microsoft SDKs\Windows\v7.0>setenv /x64 /release

关于可能发生的事情的任何想法?提前Tnx！

Any ideas of what might have happened? Tnx in advance!

推荐答案

从python脚本运行时遇到相同的错误:

I got the same error when running from a python script:

os.system("python setup.py build_ext --inplace")

同时

python setup.py build_ext --inplace

通过命令提示符工作.

原因是我的测试包的名称是"cython" ...让我愚蠢

The reason was that the name of my test package was "cython"... stupid me
