Mac OS 10.10上的ipython - 找不到命令

Question

我想让ipython在Mac OS 10.10中运行.

问题:

$ ipython

回报

-bash: ipython: command not found

背景:

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

which python =

/usr/local/bin/python

brew info 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) *

要安装ipython,我跑了

pip install ipython[all]

所以... pip show ipython =

---
Metadata-Version: 2.0
Name: ipython
Version: 4.0.0
Summary: IPython: Productive Interactive Computing

最后, echo $PATH =

/Users/[username]/depot_tools:/usr/local:/usr/local/lib:/Users/[username]/depot_tools:/usr/local:/usr/local/lib:/usr/local/lib/python2.7/site-packages:/Users/[username]/depot_tools:/usr/local:/usr/local/lib:/usr/local/git/current/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/sbin:/opt/X11/bin

谁能告诉我我做错了什么？

Answer 1

我遇到了同样的问题，但解决了。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！您的计算机中有 IPython。

然后在终端上运行此命令。

alias ipython='python -m IPython'

最后你可以再次尝试 ipython 命令。

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

Answer 2

我试图用“pip install jupyter” 安装jupyter 。http://jupyter.readthedocs.org/en/latest/install.html

然后我在运行 ipython 时遇到类似的错误。我确实尝试了 Stackoverflow 上有关安装 ipython 的所有解决方案。

最后，我安装了Anaconda然后运行conda install jupyter。现在一切正常。

我的环境：

1. Python 2.7
2. Mac OS X 埃尔卡皮坦
