venv doesn't create activate script python3

When trying to create a virtulenv using venv with python 3 on ubuntu it isn’t creating an activate script. It conitunally exits with an error 1.

Following docs and other posts on SO such as https://stackoverflow.com/a/19848770

I have tried creating it 2 different ways.

sayth@sayth-TravelMate-5740G:~/scripts$ python3 -m venv test4
Error: Command '['/home/sayth/scripts/test4/bin/python3', '-Im', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1
sayth@sayth-TravelMate-5740G:~/scripts$ source test4/bin/activate
bash: test4/bin/activate: No such file or directory
sayth@sayth-TravelMate-5740G:~/scripts$ ls test4/bin/
python  python3

or

sayth@sayth-TravelMate-5740G:~/scripts$ pyvenv-3.4 test5
Error: Command '['/home/sayth/scripts/test5/bin/python3.4', '-Im', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1
sayth@sayth-TravelMate-5740G:~/scripts$ ls test5/bin/
python  python3  python3.4

How can I get it to fully create a venv?

If I do it as below with stil no success unsure what the issue is?

sayth@sayth-TravelMate-5740G:~/scripts$ python3 -Im venv panda3
Error: Command '['/home/sayth/scripts/panda3/bin/python3', '-Im', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1
sayth@sayth-TravelMate-5740G:~/scripts$ python3 -m venv panda4
Error: Command '['/home/sayth/scripts/panda4/bin/python3', '-Im', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1
Solution

  • Looks like you are using Ubuntu 14.04. It was shipped with a broken pyvenv. There is a simple work around to create venv using Python 3

    1. Create venv without pip 

    python3 -m venv --without-pip test4

    or 

    pyvenv-3.4 --without-pip test4

    2. Get pip in your env

    source test4/bin/activate
curl https://bootstrap.pypa.io/get-pip.py | python
deactivate
source test4/bin/activate

    or 

    pyvenv-3.4 --without-pip myvenv
source ./myvenv/bin/activate
wget https://pypi.python.org/packages/source/s/setuptools/setuptools-3.4.4.tar.gz
tar -vzxf setuptools-3.4.4.tar.gz
cd setuptools-3.4.4
python setup.py install
cd ..
wget https://pypi.python.org/packages/source/p/pip/pip-1.5.6.tar.gz
tar -vzxf pip-1.5.6.tar.gz
cd pip-1.5.6
python setup.py install
cd ..
deactivate
source ./myvenv/bin/activate
