[NEST Users] Nest install

When installing Nest, I encountered the following error " Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/home/yao/Documents/nest-simulator-2.16.0-build/lib/python2.7/site-packages/nest/__init__.py", line 70, in <module> from . import pynestkernel as _kernel # noqa ImportError: dynamic module does not define module export function (PyInit_pynestkernel) " I tried nest 2.16.0, nest 2.20.0, and nest 2.18.0, but all encountered this error. I haven't encountered it before, so I would like to ask for advice on how to do it
