我在尝试打开 jupyter notebook 时遇到了问题

我开始使用 Anaconda，但无法打开 jupyter 笔记本。当我尝试时，它发出应用程序启动错误，显示以下内容：

Traceback (most recent call last):

答案1

这对我有用，你可以尝试一下：

pip uninstall pyzmq

然后：

pip install pyzmq

我在 anaconda prompt 上运行这些命令

答案2

我在使用 jupyter notebook 和 spyder 时也遇到了类似的问题。

我的修复方法是：

  1. 卸载 anaconda 和 python3.7（或您已安装的任何版本）
  2. 删除“C:\Users\pc\AppData\Roaming\Python”Python 文件夹
  3. 重新安装 anaconda

然后，在 anaconda prompt 中写入

jupyter notebook

或者

spyder

就是这样。希望它能起作用
