Jupyter notebook 权限错误

I'm having some issues with opening Jupyter. I just installed Anaconda, but got the same error as before when I try to write "Jupyter notebook" in terminal.

Johans-MBP:~ JDMac$ Jupyter notebook
Traceback (most recent call last):
  File "/Users/JDMac/anaconda3/lib/python3.5/site-packages/traitlets/traitlets.py", line 501, in get
    value = obj._trait_values[self.name]
KeyError: 'runtime_dir'

During handling of the above exception, another exception occurred:

由于我对这一切几乎一无所知，我需要一些帮助:)
