Question

抱歉，这里有点初学者问题。我下载了Jupyter笔记本附带的Anaconda库以及其他一些希望学习Python的程序。每次我尝试打开Jupyter Notebook时，它会指示我localhost:8888/tree的网页并给我以下错误：

404：Not Found error网页。

编辑：使用终端安装pip后，收到以下错误消息：

Exception:

During handling of the above exception, another exception occurred:

Answer 1

你要去的网页是什么。如果你正在使用Windows。转到cmd提示符。输入jupyter notebook。如果你在mac os x中。转到终端并键入jupyter notebook。 LMK，如果它不起作用。一旦你触发jupyter笔记本，这也是链接。：

http://localhost:8888/tree

LMK知道

您的错误消息提供：

首次连接时，将此URL复制/粘贴到浏览器中，使用令牌登录： http://localhost:8891/?token=dcf34cac4a27f8b92397fcec424b228b308a4588f0473fd6

首先在浏览器中尝试，然后查看错误是否仍然存在。
