venv doesn't create activate script python3

Question

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

Answer 1

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

Answer 2

Anaconda involucred.

If you are using Anaconda or Miniconda this solution may help:

Conda manages python itself as a package, so that conda update python is possible, in contrast to pip, which only manages Python packages. Conda is available in Anaconda and Miniconda (an easy-to-install download with just Python and conda).

So, this command would help:

conda update python

very disturbing for me but well, hands to the keyboard in a terminal window: (click here, see the picture)

Thanks for your attention, have a nice day!

Answer 3

The command:

python3 -m virtualenv env

works for me, whereas:

python3 -m venv env

does not.

Answer 4

This worked for me:

python3 -m venv --without-pip test4

Once I typed that in the terminal, the "test4" venv was created. And the 'activate' script was also created in the 'bin' directory.

To anyone using python3, having trouble with this, just substitute the name of the directory you want to create for "test4" (or rename it later).

That should do it.
