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 15 Answers
@yushulx 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
Try to create the virtual environment using directly venv module
python3 -m venv my_env 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.
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.
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.
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 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 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.
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 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.
Install venv package using this command
sudo apt install python3.8-venv Create virtual environment using this command
python3 -m venv env Activate virtual environment using this command
source env/bin/activate Decative virtual environment using this command
deactivate 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.
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 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 if you have tried to install using pip command earlier uninstall
pip uninstall virtualenv then try to create virtual env
virtualenv my_name ncG1vNJzZmirpJawrLvVnqmfpJ%2Bse6S7zGiorp2jqbawutJobWxsaWZ%2Fc32OpqadrZyau7DAxaisp5yVp7%2Bwvoynpmaln5nCrbGMp5imnZRiw6q%2B066YpZ2eq3q0scSdZJ6lkpqxbsLImmSaqKBisaLAwGauoZ2eYrY%3D
