I'm trying to follow a version control tutorial in an IPython Notebook by Fernando Perez, a static version of which can be found here.

他广泛使用 %% bash 魔法，但当我使用它我收到以下错误：

He uses the %%bash magic extensively, but When I use it I get the following error:

即使我使用！git 命令;一切正常。

推荐答案

无效的原因是您在Windows上运行。 Windows确实
没有bash而是cmd。与此一致的是，ipython没有 %% bash
magic，但 %% cmd magic 。您可以尝试将其命令重写为 %% cmd ，但是
要注意cmd与bash不同，因此他的命令可能无法正常运行
。

The reason that is not working is that you are running on windows. Windows does not have bash but cmd. In line with that is that ipython does not have %%bash magic, but %%cmd magic. You could try rewriting his commands to %%cmd, but beware that cmd is different from bash and so his commands might not work quite right.

要在Windows上运行此笔记本，您需要安装cygwin并从那里运行ipython
。你不需要在cygwin中安装ipython - 运行windows
ipython就好了，但你必须从cygwin shell运行它。

To run this notebook on windows, you need to install cygwin and run ipython from there. You do not need to install ipython in cygwin – running the windows ipython is just fine, but you have to run it from a cygwin shell.

更新：经过一番研究，我发现是什么让cygwin shell
特别：它将bash放入其PATH中。所以你毕竟不需要cygwin。安装
git就足够了。只需创建名为 notebook.bat 的批处理文件或以下内容为
的内容：

Update: After some research, I found out what makes the cygwin shell special: It puts bash in its PATH. So you don’t need cygwin after all. Having git installed is enough. Just create a batch file named notebook.bat or something with the following content:

@echo off
set PATH=%PATH%;C:\Program Files\Git\bin
ipython notebook

使用此批处理文件运行笔记本时， %% bash 命令将可用，工作。

When you run your notebook using this batch file, the %%bash command will be available and working.
