编译.pyx文件工作正常但是当我输入时突然出现错误:

python setup.py build_ext --inplace

我收到错误:

c:\Python27\cython\helloworld>python setup.py build_ext --inplace

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"])]
)

它已经有好几次了,有些东西已经改变但是当我用Google搜索并搜索这个问题时,我找不到任何信息。我正在使用Python 2.7 64位,最新版本的Cython并编译我使用Windows SDK C / C ++编译器的文件并通过运行来准备环境:

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

关于可能发生的事情的任何想法? Tnx提前!

3 个答案:

答案 0 :(得分:2)

我遇到了同样的错误。 工作了一整天,直到我意识到我已经按照一些博客条目在我的目录中创建一个cython.py文件,其中包含一些如何编译的信息。 我不记得我在哪里找到这个但是删除这个文件一切正常

答案 1 :(得分:1)

从python脚本运行时出现了同样的错误:

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

python setup.py build_ext --inplace

从命令promt工作。

原因是我的测试包的名称是“cython”...愚蠢的我

答案 2 :(得分:0)

我不确定这会有什么帮助,但是当我收到此错误时,我删除了所有.pyc文件并通过IDLE再次运行脚本(在IDLE中打开并单击F5)然后它运行正常。
