我按照说明运行 ipython.exe 笔记本：

现在如果我运行 jupyter notebook，我会得到：

C:\Miniconda3\Scripts>jupyter notebook Traceback（最近调用最后）：文件“C:\Miniconda3\Scripts\jupyter-script.py”，第 5 行，在 sys.exit(jupyter_core.command.main()) 文件“C:\Miniconda3\lib\site-packages\jupyter_core\command.py”，第 186 行，主要是 _execvp(command, sys.argv[1:]) 文件“C:\Miniconda3\lib\site-packages\jupyter_core\command.py”，第 104 行，在 _execvp raise OSError('%r not found' % cmd, errno.ENOENT) OSError: [Errno None not found] 2

我需要将我的工作保存为 ipython 笔记本。我该怎么做？

【问题讨论】：

这不是你的错。您的安装不完整或损坏。此外，Jupyter Inc. 忽略了向后不兼容更改的第一定律（即“不要”），这意味着您的教程不准确。不幸的是，我不知道从哪里获得好的安装或最新的教程。

【解决方案1】：

就像zwol 所说，您的安装可能已经搞砸了。您可以做两件事。

完全删除您的 miniconda 安装，然后重试。
创建一个新环境并在那里安装 ipython/jupyter。我会先试试这个。

conda create -n myenv python=3 activate myenv conda install jupyter jupyter notebook

【解决方案2】：

我遇到了同样的问题，但我创建了一个“testenv”并在那里运行 jupyter notebook，它对我有用。主安装有些问题，但您可以在不同的环境中安装工作。
