编译.pyx文件工作正常,但当我键入以下内容时,突然出现错误:
python setup.py build_ext --inplace我得到了错误:

AttributeError: 'module' object has no attribute 'declare'我尝试在一个简单的.pyx文件helloworld上运行它:
def say_hello_to(name):
print "Hello %s!" %name使用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"])]
)它已经工作了几次,有些东西已经改变了,但当我在谷歌上搜索这个问题时,我找不到任何信息。我使用的是Python 2.7 64位,Cython的最新版本,为了编译文件,我使用Windows SDK C/C++编译器,并通过运行以下命令准备环境:
C:\Program Files\Microsoft SDKs\Windows\v7.0>set DISTUTILS_USE_SDK=1
C:\Program Files\Microsoft SDKs\Windows\v7.0>setenv /x64 /release你知道可能发生了什么吗?提前使用Tnx!

从python脚本运行时,我得到了相同的错误:
os.system("python setup.py build_ext --inplace")而
python setup.py build_ext --inplace从命令提示符开始工作。
原因是我的测试包的名字是"cython"...愚蠢的我

我也犯过同样的错误。我花了一整天的时间,直到我意识到我已经跟踪了一些博客条目,在我的目录中创建了一个cython.py文件,其中包含一些如何编译的信息。我不记得我是在哪里找到这个文件的,但是通过删除这个文件,一切工作正常。

我不确定这是否有帮助,但当我收到这个错误时,我删除了所有的.pyc文件,并通过IDLE再次运行脚本(在IDLE中打开并单击F5),然后它工作得很好。
