ipython: команда не найдена на OSX

Question

Я установил научную среду python (numpy, scipy, matplotlib, pandas, ipython) некоторое время назад на OSX, используя пиво, и либо pip, либо easy_install (или 2 из них, я не запомнить). Теперь, если попытаться запустить IPython я получаю:

-> ipython 
-bash: ipython: command not found 

Тогда я сделал:

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

find: ./dev/fd/3: Not a directory

Я был удивлен, чтобы не видеть никакого каталога/бен.

Затем я попытался переустановить IPython

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

Это действительно сбивает с толку. Любая идея приветствуется.

Answer 1

Создать .pydistutils.cfg в ваших $HOME следующего содержания

[global] 
verbose=1 

[install] 
install-scripts=$HOME/bin 

[easy_install] 
install-scripts=$HOME/bin 

Run

pip install -U --user --force ipython 

Посмотрите https://github.com/pypa/pip/issues/426

Answer 2

обходной путь (по крайней мере, для IPython), чтобы добавить эти строки в ~/.pydistutils.cfg : [install] install-data=/usr/local install-scripts=/usr/local/bin
