今天遇到的“OS ERROR, permission denied” 如何解决的

lirh@ubuntu:~$ jupyter notebook
Traceback (most recent call last):
File "/home/lirh/.local/lib/python3.5/site-packages/traitlets/traitlets.py", line 528, in get
value = obj._trait_values[self.name]
KeyError: 'runtime_dir'

During handling of the above exception, another exception occurred:

PermissionError: [Errno 13] Permission denied: '/home/deploy'

只要把命令改成：

lirh@ubuntu:~$ sudo jupyter notebook

就可以成功运行
