ModuleNotFoundError: No module named 'virtualenv.seed.embed.via_app_data' when I created new env by virtualenv

I was creating a new virtual environment on Ubuntu 20.04:

$ virtualenv my_env

But it gave an error:

ModuleNotFoundError: No module named 'virtualenv.seed.embed.via_app_data'

Other info:

$ virtualenv --version
virtualenv 20.0.17 from /usr/lib/python3/dist-packages/virtualenv/__init__.py

virtualenv is installed by default with python itself and when you install virtualenv via pip3 and try to create virtual environment using pipenv you will get this error:

ModuleNotFoundError: No module named 'virtualenv.seed.embed.via_app_data

Check the version of installed virtualenv using apt list --installed:

python3-virtualenv/focal,focal,now 20.0.17-1 all [installed,automatic] with the installed virtualenv by pip3:

virtualenv             20.4.0

Default installation of virtualenv is different with pip3 installed virtualenv

So when you try to create a virtual environment using pipenv (for example installing Django in a directory home/user/django with pipenv install django~=3.1.5 you will get that error.

The solution is to remove installed virtualenv using pip3 uninstall virtualenv and use the default installation of virtualenv. This time when you create virtual environment with pipenv it will create it successfully.

When we use pip3 or python3 to install virtualenv then I got that error too. I had to run each time to create virtualenv (my_env is virtual environment name)

python3 -m virtualenv my_env

But if I install it using

sudo apt install virtualenv

Then virtualenv command works fine.

virtualenv my_env

I also faced the same issue but after removing virtualenv which was installed with pip3, I could get rid of this error. Uninstall virtualenv with below command (don't forget to use sudo)

sudo pip3 uninstall virtualenv

After this, virtualenv command works totally fine.

To fix this on Ubuntu 20.04, I had to uninstall virtualenv from the system: apt remove python3-virtualenv, and reinstall it using pip: pip install --user virtualenv --force-reinstall. I had errors about dependencies conflicts, I fixed them by calling pip install --user ${package} --force-reinstall for every package involved.

I fixed this error by removing all virtualenv and virtualenvwrapper related packages on system and reinstall the virtualenv and virtualenvwrapper with pip with below command(as i use ubuntu, so below only show apt) remove all packages shown in below result

apt list --installed | grep virtualenvwrapper 
apt list --installed | grep virtualenvwrapper

install virtualenv virtualenvwrapper with pip

pip install virtualenvwrapper virtualenvwrapper

set ~/.zshrc

export WORKON_HOME=$HOME/.virtualenvs
export PROJECT_HOME=$HOME/amd
export VIRTUALENVWRAPPER_SCRIPT=/home/robot/.local/bin/virtualenvwrapper.sh
export VIRTUALENVWRAPPER_PYTHON=$(which python3)
source /home/robot/.local/bin/virtualenvwrapper.sh

It means that there are two virtualenv in your system. One is "pip install" by sudo or root, the other may be installed by apt(if you are using ubuntu os) Just uninstall one of them and the error should be fixed.

If someone encounters this problem inside existing env (when for example using pyenv) you can also use command below (found on GitHub when tried to fix poetry virtual env installation):

pip install --force-reinstall virtualenv

I too had this issue. What I found is it is a permissions issue. For some unknown reason ownership of my home directory was off. I did a chown -R for the directory I was using for my project making myself the owner of my own directory and now everything works as normal.

I want to have virtualenvwrapper. On Debian 10 testing I did:

apt remove python3-virtualenvwrapper  # not purge, I want no changes in ~/.virtualenvs/
apt purge python3-virtualenv
/usr/bin/python3.8 -m pip install --force-reinstall virtualenvwrapper
/usr/bin/python3.8 -m pip install --force-reinstall virtualenv==20.0.23

.24 no longer works. I hope it will be solved sometimes...

EDIT 2021.01: I have changed my stack to: pyenv + pyenv-virtualenvwrapper + poetry. Ie. I use no apt or pip installation of virtualenv or virtualenvwrapper, and instead I install pyenv's plugin pyenv-virtualenvwrapper. This is easier way.
