Start guide for mkvirtualenv

Esta es una guía para el uso de entornos virtules con virtualenvwrapper.

Preparar un entorno virtual

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
