Jupyter notebook Jupyter ImportError:无法导入名称'；创建提示应用程序&x27；ubuntu 18.04

我已经在Ubuntu 18.04上安装了jupypter。当我尝试打开.ipynb文件时，它会显示尝试连接到服务器，但最终失败。 当我查看控制台时，我看到以下错误：

ImportError:无法导入名称“创建\提示\应用程序” 如下

sudopip3卸载ipython

sudo pip3安装ipython

这个错误为我解决了，试试看

sudo pip3安装'prompt toolkit=2.0.0'--强制重新安装
对我来说，解决方案是遵循以下步骤：

python3 -m venv venv
source venv/bin/activate
pip install jupyter
python -m jupyter notebook

我希望这对任何人都有帮助。
最好使用以下命令升级
jupyter console
：

pip3 install --upgrade --force jupyter-console

然后它将与更高版本的
prompt toolkit
兼容

正确答案。上帝保佑我，这对我有用。谢谢
