Jupyter 加载空白网页

Question

系统崩溃后，jupyter 已停止在端口 8888 上工作。

菜单导航工作正常，但创建新笔记本或加载我在计算机崩溃之前正在处理的笔记本会导致网页空白。

我正在使用 Chrome，运行ning on Mac OS X.

我尝试过浏览器历史记录和缓存清除（在类似问题的答案中推荐），重新启动并重新安装 jupyter。最后一个似乎让我在控制台中出现更多错误（或者至少我不记得看到最后两个，但无法仔细检查）。

因为它仍然在端口 8889 上工作，所以我继续使用它。然而，8889 刚刚开始以同样的方式失败 - 我现在正在使用端口 8890。在终端中调用 'netstat -anp tcp' 不会在端口 8888 或 8889 上显示任何运行ning。

以下是控制台的当前输出，来自尝试运行它在端口 8888 上的输出：

Uncaught SyntaxError: Invalid or unexpected token

Answer 1

遇到同样的问题 (12.03.2019)
（也许）第一个解决方案：清理浏览器缓存。有时它能解决问题。

如果成功 == false

尝试将笔记本降级到 5.7.4（或 5.7.5）

pip uninstall notebook
pip install notebook==5.7.4 (or 5.7.5)

它帮助了我
