没有名为“prompt\u toolkit.formatted\u text”的模块

Question

我对Jupyter笔记本电脑一无所知

目前，我使用的笔记本与R，它是工作得很好

现在，我尝试将其与Python一起使用，并收到以下错误

[I 09:00:52.947 NotebookApp] KernelRestarter: restarting kernel (4/5), new random ports

希望有人能帮助我

Answer 1

ipython` 7.0.1 has requirement prompt-toolkit<2.1.0,>=2.0.0, but you'll have prompt-toolkit 1.0.15 which is incompatible

升级prompt-toolkit将解决此问题

pip install --upgrade prompt-toolkit

Answer 2

我也有同样的问题，我在Github中修复了它的说法： https://github.com/jupyter/notebook/issues/4079

• 打开Anaconda提示符键入

  python -m ipykernel install --user
  

Answer 3

使用Anaconda virtualenv创建内核更稳定

遵循以下步骤

1. 执行Anaconda提示符
2. 键入conda create --name $ENVIRONMENT_NAME R -y
3. 键入conda activate $ENVIRONMENT_NAME
4. 键入python -m ipykernel install
5. 类型ipython kernel install --user --name $ENVIRONMENT_NAME

然后，您将有一个名为“R”的新jupyter内核，其中安装了R
