Preparing a virtual environment
===============================

``virtualenv MyVE``

``source MyVE/bin/activate``

``pip install -r requirements.txt``



Virtualenvwrapper
=================

mkdir ~/.virtualenvs

apt install virtualenvwrapper
pip install virtualenvswrapper

si no está el pip, instalar: (virtualenv y python-setuptools)

sudo apt install python3-pip


----------poner esto en .bashrc
export WORKON_HOME=$HOME/.virtualenvs
export VIRTUALENVWRAPPER_VIRTUALENV=/usr/local/bin/virtualenv
export VIRTUALENVWRAPPER_VIRTUALENV_ARGS='--no-site-packages'
export VIRTUALENVWRAPPER_PYTHON=$(which python3)                                                                                      

Que puede fallar:

1) virtualenvwrapper

La ubicacion del script virtualenvwrapper.sh depende de la
distribucion de linux:

Mint:
source /usr/local/bin/virtualenvwrapper.sh

CBPP:
source $HOME/.local/bin/virtualenvwrapper.sh


1) virtualenv

en la variable VIRTUALENVWRAPPER_VIRTUALENV
poner la ubicación de virtualenv:

$ which virtualenv


3) python

Si da este error:

 source $HOME/.local/bin/virtualenvwrapper.sh
/usr/local/bin/python3: Error while finding module specification for 'virtualenvwrapper.hook_loader' (ModuleNotFoundError: No module named 'virtualenvwrapper')
virtualenvwrapper.sh: There was a problem running the initialization hooks.

If Python could not import the module virtualenvwrapper.hook_loader,
check that virtualenvwrapper has been installed for
VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python3 and that PATH is
set properly.

probar hacer esto:

reemplazar:
export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3
por:
export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python
