ubuntu配置jupyter

ubuntu安装Anaconda3之后会自动安装jupyter，Anaconda下载地址推荐清华大学的下载地址，具体安装教程请看这里。

进入Anaconda虚拟环境后，cd到想要打开文件()的目录,输入

jupyter notebook

然后会报一大堆错误，如下：

        mkdir(name, mode)
    PermissionError: [Errno 13] Permission denied: '/home/user07/.local/share/jupyter'

主要原因就是最后一句，anaconda3中os.py有一个在文件夹'/home/user07/.local/share/jupyter'下的mkdir操作，而当前用户没有权限，所以需要：

sudo chmod 777 ~/.local/share/

再次输入：

jupyter notebook

大功告成！
