最简单cython编译出现问题，大神求帮忙

Question

在使用cython编译最简单的helloworld程序时出现如下问题：
本人使用的是anaconda3+vs2015

Compiling helloworld.pyx because it changed.
[1/1] Cythonizing helloworld.pyx
running build_ext
Traceback (most recent call last):
  File "setup.py", line 5, in <module>
    ext_modules = cythonize("helloworld.pyx")
  File "D:\anaconda\lib\distutils\core.py", line 148, in setup
    dist.run_commands()
  File "D:\anaconda\lib\distutils\dist.py", line 955, in run_commands
    self.run_command(cmd)

    if self.ld_version >= "2.10.90":
TypeError: '>=' not supported between instances of 'NoneType' and 'str'

helloworld.pyx文件中的代码

 print('hello world')

setup.py中代码

 from distutils.core import setup
from Cython.Build import cythonize

setup(
    ext_modules = cythonize("helloworld.pyx")
)

看了下代码中的注释：

         self.gcc_version, self.ld_version, self.dllwrap_version = \
            get_versions()
        self.debug_print(self.compiler_type + ": gcc %s, ld %s, dllwrap %s\n" %
                         (self.gcc_version,
                          self.ld_version,
                          self.dllwrap_version) )

        # ld_version >= "2.10.90" and < "2.13" should also be able to use
        # gcc -mdll instead of dllwrap
        # Older dllwraps had own version numbers, newer ones use the
        # same as the rest of binutils ( also ld )
        # dllwrap 2.10.90 is buggy
        if self.ld_version >= "2.10.90":
            self.linker_dll = "gcc"
        else:
            self.linker_dll = "dllwrap"

感觉你应该最好用gcc来编译，而不是vc++，因为后者版本号的格式和这个判断不兼容。
或者你试试看修改cygwinccompiler.py文件，把这个判断注释下。
