ModuleNotFoundError: No module named 'virtualenv.seed.embed.via_app_data' when I created new env by virtualenv
PythonVirtualenvPython Problem Overview
I had install virtualenv, created a venv by virtualenv since last month but now I can't create other env. In Ubuntu 20.04 terminal, I had tried:
$virtualenv my_env
But its result is
ModuleNotFoundError: No module named 'virtualenv.seed.embed.via_app_data'
After that, I checked its version:
$virtualenv --version
and get:
virtualenv 20.0.17 from /usr/lib/python3/dist-packages/virtualenv/__init__.py
I also checked it by $pip3 list and virtualenv still exists. It seem that problem came after I had install Anaconda.

I also ran into the same issue. I installed both via pip3
and via sudo apt install python3-virtualenv
and it gave me an error but after I ran pip3 uninstall virtualenv
I could create a virtualenv without issue
Solution 2 - Python
Try to create the virtual environment using directly venv module
python3 -m venv my_env
Solution 3 - Python
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
mine is:
python3-virtualenv/focal,focal,now 20.0.17-1 all [installed,automatic]
with the installed virtualenv
by pip3
min is :
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/djano
with pipenv install django~=3.1.5
you will get that error
the solution is 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.
Solution 4 - Python
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.
Solution 5 - Python
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.
Solution 6 - Python
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
Solution 7 - Python
When I installed virtualenv
via pip3
, it failed to run virtualenv
command. Then I changed the installation via:
sudo apt install python3-virtualenv
The virtualenv
command can normally work.
Solution 8 - Python
I also had same issue, seems installed version has different user level so I followed their doc and below one work for me:
python3 -m virtualenv --help
To create new environment:
python3 -m virtualenv my_env
Solution 9 - Python
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.
Solution 10 - Python
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.
Solution 11 - Python
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
