我按照说明操作ipython.exe笔记本：

现在如果我运行jupyter笔记本，我得到：

  

C：\ Miniconda3 \ Scripts＆gt; jupyter notebook Traceback（最近的电话   last）：文件＆＃34; C：\ Miniconda3 \ Scripts \ jupyter-script.py＆＃34;，第5行，in          sys.exit（jupyter_core.command.main（））文件＆＃34; C：\ Miniconda3 \ lib \ site-packages \ jupyter_core \ command.py＆＃34;，第186行，   在主要       _execvp（command，sys.argv [1：]）File＆＃34; C：\ Miniconda3 \ lib \ site-packages \ jupyter_core \ command.py＆＃34;，104行，   在_execvp中       引发OSError（＆＃39;％r未找到＆＃39;％cmd，errno.ENOENT）OSError：[Errno None not found] 2

我需要将我的工作保存为ipython笔记本。我该怎么办？

Answer 1

就像zwol所说，您的安装可能已经搞砸了。你可以做两件事。

1. 完全删除您的miniconda安装，然后重试。

2. 创建一个新环境并在那里安装ipython / jupyter。我先试试这个。

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

Answer 2

我遇到了同样的问题，但我创造了一个＆＃39; testenv＆＃39;并在那里运行jupyter笔记本，它对我有用。 有些东西搞砸了主安装，但你可以在不同的环境中安装工作。
