Using snap I installed python38 on an Ubuntu 18 server. now I want to create a new virtual environment but I fail as these commands fail:
virtualenv --python /snap/bin/python38 myvenv
Running virtualenv with interpreter /snap/bin/python38
python3.8: can't open file '/usr/lib/python3/dist-packages/virtualenv.py': [Errno 2] No such file or directory
test -f /usr/lib/python3/dist-packages/virtualenv.py; echo "it exists!"
# OUTPUT: it exists!
# --------------------------------------------------------------------------------
python38 -m venv myvenv
The virtual environment was not created successfully because ensurepip is not
available. On Debian/Ubuntu systems, you need to install the 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.
Failing command: ['/tmp/myvenv/bin/python3.8', '-Im', 'ensurepip', '--upgrade', '--default-pip']
This is my first experience with snap, and I'm unsure how I can install python3-venv to make it work.
Any help would be appreciated
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
#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
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.
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
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 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
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.
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
How to install virtualenv properly on AWS Ubuntu 18.04 AMI. I have tried various ways such as through pip and through apt-get but I am not able to either properly install or configure it. Whenever I am running command virtualenv --python=python3.6 .venv or virtualenv --version it is giving me this error:
ERROR:root:failed to read config file /home/ubuntu/.config/virtualenv/virtualenv.ini because PermissionError(13, 'Permission denied')
How to properly install and configure virtualenv?
First check if Python3 is installed
apt list installed | grep -i python3
After that
python3 -m venv my_app/env
Ubuntu 16 and python 3.5.2
Trying to add some python scripts in a folder /opt/python_scripts
Tons of SSL errors on any pip install so I upgraded pip to 19.2.1
The only way I could upgrade it was with
sudo python -m pip install --trusted-host pypi.python.org --trusted-host files.pythonhosted.org --trusted-host pypi.org --upgrade pip
didn't help still got SSL errors but at least seems to work anyway
I want to try and get in the habit of using python environments to isolate requirements etc.
Following pipenv instructions...
I made a python_scripts folder under opt and installed pipenv
/opt/python_scripts$ pip3 install pipenv
but
/opt/python_scripts$ pipenv shell
PermissionError: [Errno 13] Permission denied: 'Pipfile'
/opt/python_scripts$ sudo pipenv shell
sudo: pipenv: command not found
Assuming the correct thing to do is to add my scripts under the opt folder.
How can I get pipenv to work under that folder?
Let's first make sure pyhon is correct installed do the following python3 -V assuming that it's properly installed you get the correct version no error's or warnings do this sudo apt install python3-pip once installed verify pip3 list if you have errors do the following pip3 install virtualenvwrapper You will have to add the command to source/usr/local/bin/virtualenvwrapper.sh to your shell startup so do the following
nano .bashrc
export WORKON_HOME=$HOME/.virtualenvs
export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3
export PROJECT_HOME=$HOME/Devel
source /usr/local/bin/virtualenvwrapper.sh
now run this command source ~/.bashrc I hope now your up and running, if you real need to use the pipenv then do the following sudo apt-get install python3-venv then run this to verify pipenv shell
Good lucky and happy coding.
I am trying to install Django in my windows 7 machine, as a prerequisite, I am installing virtualenvwrapper:
pip install virtualenvwrapper-win
But it throws the following error:
Error [WinError 87] The parameter is incorrect while executing command
python setup.py egg_info
Could not install packages due to an EnvironmentError: [WinError 87] The paramet
er is incorrect
[NOTE]:
Python version : Python 3.7.0b4
pip version: pip 10.0.1
Try using pyenv:
Step 1:
install virtualenv using pip
pip install virtualenv
Step 2
In a folder, open cmd and run:
python -m venv virtualenvname
eg:
python -m venv india
Step 3: Activate your Virtual environment by:
india\Scripts\activate
Note: S of sripts has to be in caps
Now you must see india before location in your cmd. If yes then your virtual env has been activated.
Something Like this:
(india) D:\dev\python\django\
pip3 -m venv yourprojectname
Are you trying my command. I got the error like you did with this command I got the problem
but, you can apply the following commands
py -m pip install --user virtualenv
py -m virtualenv env
OR
python3 -m pip install --user virtualenv
python3 -m virtualenv env
