python - MacOS 10.10 上的 ipython - 找不到命令

Question

我正在尝试让 ipython 在 Mac OS 10.10 中工作。

问题:

$ ipython

返回

-bash: ipython: command not found

上下文:

我在 MacOS 10.10 上运行 python2.7。我通过 brew 安装了 python。一些信息:

哪个python =

/usr/local/bin/python

酿造信息 python =

python: stable 2.7.10 (bottled), HEAD
Interpreted, interactive, object-oriented programming language
https://www.python.org
/usr/local/Cellar/python/2.7.10_2 (4977 files, 77M) *

为了安装 ipython，我运行了

pip install ipython[all]

所以... pip show ipython =

谁能告诉我我做错了什么？

我遇到了同样的问题，但已解决。您需要确保首先通过终端上的此命令安装 IPython。

$python -m IPython

然后它会显示这个结果:

恭喜!你的电脑里有 IPython。

然后在终端上运行这个命令。

alias ipython='python -m IPython'

终于可以再次尝试 ipython 命令了。

您可以将此命令行添加到~/.bash_profile 文件中以永久使用。它对我来说很好。
