我的电脑是ubuntu14LTS,安装anaconda3.6,之后运行jupyter notebook出现下面的错误
qqblack@tanzi-PC:~$ jupyter notebook

问题解决了，参考这篇帖子 http://blog.sciencenet.cn/blog-419883-537247.html shell中输入命名： sudo hostname localhost 结果发现我不能使用sudo了，提示：localhost解析失败，而且我的电脑名被改成了localhost 去/etc/hosts文件里去修改，加上一行 127.0.0.1 localhost (原来的127.0.0.1 xiuga-PC不用删） 127.0.0.1代表当前电脑，可以对应多个账户名的 再次运行，jupyter notebook 居然成功运行了！！哈哈，侥幸发现了解决方案

总结一下： 如果不想电脑被改名的法，你应该使用命令： sudo hostname 你的电脑名 要么就和我的操作方案一样弄吧

是和环境变量有关么

配置文件里 c.NotebookApp.ip = '*' 改成 c.NotebookApp.ip = '0.0.0.0' 就行了，亲测有效。StackOverflow里看到的。 https://stackoverflow.com/questions/52706238/jupyter-throwing-error-socket-gaierror-errno-2-name-or-service-not-known
