ipython：在OSX上找不到命令 [英] ipython: command not found on OSX

问题描述

我前段时间在OSX上安装了python科学环境（numpy，scipy，matplotlib，pandas，ipython）使用brew和pip或easy_install（或者其中2个，我不记得了）。现在，如果尝试运行ipython，我会得到：

I installed the python scientific environment (numpy, scipy, matplotlib, pandas, ipython) a while ago on OSX using brew and either pip or easy_install (or the 2 of them, I don't remember). Now if try to run ipython I get:

-> ipython
-bash: ipython: command not found

然后我做了：

-> sudo find . -iname "*ipython*"

我很惊讶没有看到任何/ bin可怕ctory。

I was surprised not to see any /bin directory.

然后我尝试重新安装ipython

Then I tried to reinstall ipython

-> pip install ipython
Requirement already satisfied (use --upgrade to upgrade): ipython in /usr/local/lib/python2.7/site-packages
Cleaning up...

这真令人困惑。任何想法都是受欢迎的。

This is really confusing. Any idea is welcome.

推荐答案

在你的创建 .pydistutils.cfg $ HOME 以下内容

[global]
verbose=1

[install]
install-scripts=$HOME/bin

[easy_install]
install-scripts=$HOME/bin

运行

pip install -U --user --force ipython
