Question

I run python 2.7.6 with virtualenv, virtualenvwrapper under ubuntu 14.04. now i have installed python 2.7.9 from source. the new python interpreter is now located under

Answer 1

You need to install them under python 2.7.9 by specifying the path to correct version of pip to be used

/usr/local/bin/pip install virtualenv virtualenvwrapper

otherwise, when running pip install the sytem will use the default one (i.e. the one located at /usr/bin/pip)

Answer 2

If you have modified your virtualenvwrapper to point to python3, like I do, add the following line in your .bashrc file :

export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3

making sure that it's placed before the following line (if you have it):

source /usr/local/bin/virtualenvwrapper.sh

Then, make sure you install the virtualenv and virtualenvwrapper using:

sudo /usr/local/bin/pip3 install virtualenv virtualenvwrapper

Answer 3

source /usr/local/bin/virtualenvwrapper_lazy.sh

when use pyenv:

export PYENV_ROOT="${HOME}/.pyenv"

if [ -d "${PYENV_ROOT}" ]; then
    export PATH="${PYENV_ROOT}/bin:${PATH}"
    eval "$(pyenv init -)"
fi
export PATH

export WORKON_HOME=$HOME/.virtualenvs
export VIRTUALENVWRAPPER_SCRIPT=/usr/local/bin/virtualenvwrapper.sh
#important
source /usr/local/bin/virtualenvwrapper_lazy.sh
