ipython: comando no encontrado en OSX

Question

Instalé el entorno científico python (numpy, scipy, matplotlib, pandas, ipython) hace un tiempo en OSX usando brew y pip o easy_install (o los 2 de ellos, no recuerdo). Ahora si intento ejecutar ipython, obtengo:

-> ipython
-bash: ipython: command not found

Entonces lo hice:

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

Me sorprendió no ver ningún directorio / bin.

Luego traté de reinstalar ipython

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

Esto es realmente confuso Cualquier idea es bienvenida.

Answer 1

Crea .pydistutils.cfg en tu $HOME siguiendo los contenidos

[global]
verbose=1
[install]
install-scripts=$HOME/bin
[easy_install]
install-scripts=$HOME/bin

correr

pip install -U --user --force ipython

Eche un vistazo a https://github.com/pypa/pip/issues/426

Answer 2

La solución alternativa (al menos para ipython) es agregar estas líneas a ~/.pydistutils.cfg : [install] install-data=/usr/local install-scripts=/usr/local/bin
