Question

我正在尝试开发一个可以被C ++程序调用的python优化脚本。我从一个小例子开始。起初运行良好;但是当我尝试在python中导入一些类似于＆＃34; import numpy＆＃34;时，会出现运行时错误（没有编译错误），例如：

 Traceback (most recent call last):
  File "/*/C_nominal/addition.py", line 6, in <module>
import numpy
  File "/*/anaconda/lib/python2.7/site-packages/numpy/__init__.py", line 142, in <module>

  File "/*/anaconda/lib/python2.7/io.py", line 51, in <module>

我搜索类似问题的解决方案，例如 Numpy import fails when embedding python in c ，建议使用＆＃34; -Xlinker -export-dynamic＆＃34;编译时动态链接。但是，我的编译器显示以下错误：

ld: unknown option: -export-dynamic
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我想这可能是因为我使用的是Mac而不是linux。在官方文档 https://docs.python.org/2/extending/embedding.html#embedding-python-in-c 中，它表示可以通过获取特定于操作系统的选项命令＆＃34; * / python2.7-config --ldflags＆＃34;或

import sysconfig
sysconfig.get_config_var('LINKFORSHARED')

然而，前者没有提供有用的选择;而后者只是返回＆＃34; -u _PyMac_Error＆＃34; （有人说这是一个python bug）。然后我不知道接下来该怎么做。

有任何帮助吗？非常感谢。我使用的是Mac OS X 10.12.4。
