Question

我正在尝试使用cython将c ++代码包装到python中。我的.py代码是

from distutils.core import setup
from Cython.Build import cythonize
setup(
    ext_modules=cythonize("helloworld.pyx"),
    )

但是在用

进行编译时

python setup.py build_ext --inplace

我收到错误

running build_ext
building 'helloworld' extension
Traceback (most recent call last):
  File "setup.py", line 4, in <module>
    ext_modules=cythonize("helloworld.pyx"),
  File "C:\Python34\lib\distutils\core.py", line 148, in setup
    dist.run_commands()

    raise ValueError(str(list(result.keys())))
ValueError: ['path']

我正在开发visual studio 2010.我有点意识到这个错误是因为vcvars6.bat但我不知道如何解决它。请帮助

看起来你正在运行64位。 Visual Studio 2010是only the right choice if you are using Python 3.3 or 3.4。

我猜你没有正确设置编译器。在Python 3.4部分Ionel's Codelog中讨论了正确的安装顺序（VC ++ 2010，Windows SDK for VS 2010，.NET 4.0，创建虚假的vcvars64.bat文件，应用VC 2010 SP1，应用VC ++ 2010 SP1。

或者，您也可以尝试设置一些环境变量，如Ionel的Codelog帖子中Python 3.4部分底部所述。

我猜测你的版本错误，订单错误，或者跳过假的.bat文件或环境变量。

ValueError：['path']
