In order to avoid to sudo pip3 install virtualwrapper have installed virtualwrapper on my Ubuntu with apt:
sudo apt-get install virtualenv virtualenvwrapper
When I only use the following command I do get a python 2.7 environment:
mkvirtualenv test
In order to make a python3 environment the following commando do not work:
test@tester:~$ mkvirtualenv -p python3 test
The executable /home/test/python3 (from --python=/home/test/python3) does not exist
I order to have a python3 environement I have to use the following commando:
mkvirtualenv -p /usr/bin/python3 py3
Already using interpreter /usr/bin/python3
Using base prefix '/usr'
New python executable in /home/test/.vens/py3/bin/python3
Not overwriting existing python script /home/test/.vens/py3/bin/python (you must use /home/test/.vens/py3/bin/python3)
Installing setuptools, pkg_resources, pip, wheel...done.
Why does it not work to use the -p python3 command?
When I use the same command with virtualenv, it works:
test@tester:~$ virtualenv -p python3 test2
Already using interpreter /usr/bin/python3
Using base prefix '/usr'
New python executable in /home/test/test2/bin/python3
Also creating executable in /home/test/test2/bin/python
Installing setuptools, pkg_resources, pip, wheel...done.
According to the error you got, virtualenvwrapper passes the -p option to virtualenv using the current working directory.
You should do:
mkvirtualenv -p `which python3` test
