我第一次尝试使用此basic cython tutorial。我在使用Python 3.6.6的conda环境中。
一切正常，直到我要导入模块为止：
In [1]: import helloworld
---------------------------------------------------------------------------
ImportError Traceback (most recent call last)
<ipython-input-1-39f3e3c18221> in <module>
----> 1 import helloworld
ImportError: dlopen(/Users/billtubbs/cython-examples/helloworld.cpython-36m-darwin.so, 2): Library not loaded: @rpath/libc++abi.1.dylib
Referenced from: /Users/billtubbs/anaconda/envs/py36/lib/libc++.1.dylib
Reason: image not found
我的环境似乎有问题，所以我尝试更新所有内容：
$ conda update numpy numba pandas scipy scikit-learn pytorch matplotlib statsmodels tensorflow keras cython
我见过类似的问题，但in different circumstances却没什么新的。
您如何开始调试这样的问题？
导致此问题的步骤：
helloworld.pyx：
print("Hello World")
setup.py：
from distutils.core import setup
from Cython.Build import cythonize
setup(
ext_modules = cythonize("helloworld.pyx")
)
根据教程：
(py36) $ python --version
Python 3.6.6
(py36) $ python setup.py build_ext --inplace
Compiling helloworld.pyx because it changed.

根据@merv建议，以下是otool的输出，“显示目标文件使用的共享库的名称和版本号”：
