pyvenv-3.4 returned non-zero exit status 1

I'm in Kubuntu 14.04 , I want to create a virtualenv with python3.4. I did with python2.7 before in other folder. But when I try:

pyvenv-3.4 venv

I've got:

Error: Command '['/home/fmr/projects/ave/venv/bin/python3.4', '-Im', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1

Solution 1:

You are missing the venv lib for python 3.4, just run:

$ apt-get install python3.4-dev python3.4-venv

And then create your virtualenv

python3.4 -m venv myVenv

I got a solution installing python-virtualenv

sudo apt-get install python-virtualenv

and using

virtualenv --python=/usr/bin/python3.4 venv
