(beta) pan@pan-System-Product-Name:~/anaconda3/envs/beta/lib$ nm libpython3.7m.so | grep Py_Non 00000000003467f0 D _Py_NoneStruct 00000000000cb0f0 T _Py_Nonlocal

It's strange ？？？

解决了 link_directories -》link_libraries 且在 add_executable之前 使用anaconda在虚拟化境下就可以无需加额外参数。 但在 .b2之前要配置一下 using python : 3.7 : /home/pan/anaconda3/envs/beta/ : /home/pan/anaconda3/envs/beta/include/python3.7m : /home/pan/anaconda3/envs/beta/lib ; 在project-config.jam里(boost文件夹中)
