python - Jupyter 错误 : "No module named jupyter_core.paths"

Question

尝试打开 Jupyter Notebook (OSX 10.11.4) 时出现以下错误:

$ 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

这曾经奏效。知道如何诊断吗？
