我必须安装 Jupyter 才能完成 Udacity 的项目。按照说明操作并运行 Jupyter 后，没有一个笔记本会打开。这是日志输出：

[W 06:54:04.215 NotebookApp] The signatures database cannot be opened; maybe it is corrupted or encrypted. You may need to rerun your notebooks to ensure that they are trusted to run Javascript. The old signatures database has been renamed to /home/aulon/.local/share/jupyter/nbsignatures.db.bak and a new one has been created.

我google了一下，发现here、here、here有一些类似的问题，都没有成功。

我安装了Anaconda，还是同样的问题。

非常感谢任何帮助。

如果我无法解决这个问题，我该如何完全卸载与 jupyter 和 anaconda 相关的所有内容？我正在使用 Ubuntu 16.04。

否则，有没有其他方法可以在没有 jupyter 的情况下打开 python 笔记本？也许是 Spyder？
