How to create virtualenv in Ubuntu 18.04

  • 772

I have installed virtualenv:

pip3 install --user virtualenv

Then I was trying to create an environment for my folder with the next command: 

folder_name$ python -m venv ll_env

But instead of the desired result I've got an error:

__The virtual environment was not created successfully because ensurepip is not available.
On Debian/Ubuntu systems, you need to install python3-venv package using the following command.

apt-get install python3-venv

You may need to use sudo with that command.
After installing the python3-venv package, recreate your virtual environment.__

However despite thr error virtualenv folder named ll_env created.

I have no idea why I receive this error. I'm new to Linux. I tried to check if virtualenv exists on system with this command:

pip3 show virtualenv

And I got:

Name: virtualenv

    As pointed out by this comment by karel.

    The answer to your question is actually in your question:

    __The virtual environment was not created successfully because ensurepip is not available.
On Debian/Ubuntu systems, you need to install python3-venv package using the following command.

apt-get install python3-venv

You may need to use sudo with that command.

    To clarify, simply issue the command sudo apt-get install python-3-venv or sudo apt install python-3-venv either of which will install the python-3-venv package, provided of course that you've enabled the universe repository first.

    After installing the python3-venv package, recreate your virtual environment.__

    Good programmers will often provide hints or outright solutions to problems that are likely to occur. This is an example of the latter.
