Virtualenv - Python 3 - Ubuntu 14.04 64 bit
Solution 1
I had the same issue coming from development environments on OS X where I could create Python 3 virtual environments by simply invoking virtualenv
and the path to the target directory. You should be able to create a Python 3.x virtual environment in one of two ways:
-
Install
virtualenv
from the PyPi as you've done ($ pip3 install virtualenv
), then by calling it as a module from the command line:$ python3 -m virtualenv /path/to/directory
-
Use the venv module, which you can install through
apt-get
. (Note that Python 3.3 is when this module was introduced, so this answer assumes you're working with at least that):$ sudo apt-get install python3.4-venv
Then you can set up your virtual environment with
$ pyvenv-3.4 /path/to/directory
and activate the environment with
$ source /path/to/directory/bin/activate
You might also look at this post, which discusses differences between the venv
module and virtualenv
. Best of luck!
Solution 2
in addition to all the answers, you can use the following command.
virtualenv venv --python=python3.5
Solution 3
Also you can use this command:
virtualenv -p python3 envname
Solution 4
The venv
became standard library from python3 v3.3. So if you get more recent python3 version, this can always done by:
python3 -m venv <path-or-name-of-virtualenv>
# choose correct python3, which is the name of your python3 cmd
No need to install or download anything before hand, when succeeded, pip3 will come with the virtualenv just created. By this way, on most Linux, it will print out message to tell you what to do, for example it need python3.4-venv
.
To active the virtualenv
source <path-to-the-virtualenv>/bin/activate
# then to deactive it:
deactivate
Solution 5
Just as a point of clarification if you are on ubuntu 14.04.1, the python3.4-venv
package is not available (though it is in 14.04.5)
You can get around this by installing the python-virtualenv
package and creating virtualenvs via one of the methods described in the other answers:
virtualenv -p python3 envname
or
virtualenv envname --python=python3.x

I am trying to install virtualenv for Python 3 on Ubuntu 64bit 14.04.
I have installed pip for Python3 using:
pip3 install virtualenv
and everything works fine. Now though I am trying to use virtualenv command to actually create the environment and getting the error that it is not install (i guess because I haven't installed it for Python 2 and that is what it is trying to use)
How do I use the virtualenv for Python 3? I have searched the documentation but can't see where it says what to do.
