Jupyter加载空白网页

Question

系统崩溃后，jupyter停止了对8888端口的工作。在

菜单导航工作得很好，但是创建一个新的笔记本或者加载我在计算机崩溃前正在处理的笔记本，结果都是一个空白的网页。在

我用的是Chrome，在macosx上运行

我尝试过浏览器历史记录和缓存清除（类似问题的答案建议），重新启动并重新安装jupyter。最后一个似乎给了我更多的错误出现在控制台上（或者至少我不记得看到了最后两个，但无法再次检查）。在

由于它在8889端口上仍然有效，所以我继续使用它。但是8889以同样的方式开始出现故障—我现在使用的是端口8890。在终端中调用'netstat-anptcp'并没有显示在端口8888或8889上运行的任何内容。在

以下是控制台在端口8888上运行时的当前输出：

Uncaught SyntaxError: Invalid or unexpected token
