我在Mac上运行虚拟机Ubuntu 16.04，以及在云服务器aws ec2上运行Ubuntu 18.04。我试图在aws.ec2上运行Jupiter笔记本，并尝试通过本地Ubuntu的Web浏览器远程访问它。我可以访问远程Ubuntu（aws.ec2）终端。在按照此 link 的步骤后，我在第9步遇到了以下错误。我已经从头开始重新安装了3次所有内容（包括本地Ubuntu和aws ec2实例），但到目前为止没有任何进展。

注意1：在EC2实例上，Ubuntu有18.04版本，它自带Python 3.6.3，然后我不得不在其上安装Anaconda，现在Python版本是3.5.2，一旦我键入$python3。
注意2：尽管已将Anaconda安装到EC2中，但Python版本仍降级为3.5.2。
我检查了以下目录/usr/local/lib/，只有python3.6文件夹存在，然后我键入$sudo chmod 777 dist-packages/
然后$sjupyter notebook，复制令牌链接并与DNS组合，但仍未工作。
