jupyter notebook, KeyError: 'runtime_dir',[Errno 13] Permission denied

在用实验室的服务器运行jupyter notebook 的时候，报了如下错。

Traceback (most recent call last):File "/Users/JDMac/anaconda3/lib/python3.5/site-packages/traitlets/traitlets.py", line 501, in getvalue = obj._trait_values[self.name]

这个截图是我报的错。

我用的是实验室的服务器，多人共用。

上面显示的是我的运行目录指向了1007的jupyter，而我在服务器的编号是1019，于是我在终端上输入了

export XDG_RUNTIME_DIR = /run/user/1019

就可以运行了。

在此感谢刘大佬的帮助。

PS:如果是个人使用的Ubuntu啊什么的，直接在jupyter notebook前面加 sudo就行了。

后续还遇到了failed to write server-info的问题，也就是打开notebook后，想要对创建的notebook进行保存，但是页面右上角出现了红色的方框，上面显示kernel error。

根据终端的提示，我把permission denied 显示的那个runtime 文件里面的文件权限改成自己可以写入读取之后就好了。

具体命令可参考

chown user:user filename

chmod 777 filename
