Question

我正在使用Mac El Capitan，我需要安装iPython并且必须使用iPython notebook

我用

$ pip install ipython

安装ipython，但它返回我

Requirement already satisfied (use --upgrade to upgrade): traitlets in /Library/Python/2.7/site-packages (from ipython)

abhi ~ $ ipython
-bash: ipython: command not found

知道我做错了什么，或者我现在应该做什么？

我在我的IDLE上尝试了这个

>>> try:
    import ipython
    print "imported"
except :
    print "not installed"

它说未安装。

Answer 1

您可能需要考虑安装Anaconda，这是一个包含大多数用于科学，数学，工程和数据分析的Python包的Python发行版。这可以说是启动和运行iPython（现在的Jupyter）笔记本的最简单方法。

Answer 2

尝试在我的mac上安装ipython和jupyter时遇到类似的问题（El Capitan v10.11.6）

尝试了各种组合，包括sudo -H，--ignore <whatever people suggested>等。

唯一对我有用的事情是：

pip install --user ipython
pip install --user jupyter

您还需要添加用户python模块＆＃39;走向你的道路。一种方法是使用nano编辑.bash_profile：

export PATH = $ PATH：/ Users /您的用户ID / Library / Python / 2.7 / bin

然后只需打开一个新终端或使用source命令将其应用于开放终端。

希望它有所帮助！
