安装psycopg2后无法正常导入

Question

当我尝试使用这行简单的代码导入 psycopg2 时：

import psycopg2

出现如下错误：

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/psycopg2/__init__.py", line 50, in <module>
    from psycopg2._psycopg import (                     # noqa
ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/psycopg2/_psycopg.cpython-37m-darwin.so, 2): Library not loaded: @rpath/libssl.1.1.dylib
  Referenced from: /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/psycopg2/_psycopg.cpython-37m-darwin.so
  Reason: image not found

有人知道为什么会这样吗？
