Jupyter 错误：“没有名为 jupyter_core.paths 的模块”

Question

尝试打开 Jupyter Notebook (OSX 10.11.4) 我收到以下错误：

 $ jupyter-notebook
Traceback (most recent call last):
  File "/usr/local/bin/jupyter-notebook", line 7, in <module>
    from notebook.notebookapp import main
  File "/Users/geotheory/Library/Python/2.7/lib/python/site-packages/notebook/__init__.py", line 25, in <module>
    from .nbextensions import install_nbextension
  File "/Users/geotheory/Library/Python/2.7/lib/python/site-packages/notebook/nbextensions.py", line 23, in <module>
    from jupyter_core.paths import jupyter_data_dir, jupyter_path, SYSTEM_JUPYTER_PATH
ImportError: No module named jupyter_core.paths

这曾经有效。知道如何诊断吗？
