全新 Jupyter 安装在笔记本启动时失败 - “ImportError：无法从‘prompt_toolkit.shortcuts’导入名称‘create_prompt_application’

我刚刚在 Ubuntu 18.04 上安装了 Jupiter（v 4.4.0）。Python 版本是 3.7。当我尝试运行任何代码时，我都会收到相同的错误消息。我的内核输出如下所示。

I 01:09:32.973 NotebookApp] KernelRestarter: restarting kernel (4/5), new random ports

我尝试将 prompt-toolkit 的版本降级到 2.0.1，因为最新版本的 prompt-toolkit 似乎与 IPython 不兼容。降级到 1.0.4 也无济于事。

答案1

通过将 prompt-toolkit 降级至 1.0.15 来解决。
