venv doesn't create activate script python3

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

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!

The command:

python3 -m virtualenv env

works for me, whereas:

python3 -m venv env

does not.
