我重新启动计算机，突然因为这个我不知道如何解决的错误而无法运行jupyter Notebook。
/anaconda2/bin/jupyter_mac.command ; exit;
-bash: dirname: command not found

EncodingError: A unicode encoding or decoding error has occurred.
Python 2 is the interpreter under which conda is running in your base environment.
Replacing your base environment with one having Python 3 may help resolve this issue.
If you still have a need for Python 2 environments, consider using 'conda create'
and 'conda activate'. For example:
$ conda create -n py2 python=2
$ conda activate py2
