I'm trying to create a python virtualenv using anaconda python3.6 in ubuntu 16.04. Following https://docs.python.org/3/library/venv.html , I've tried
deploy#server:~/miniconda3/bin$ python3 -m venv ~/test
Error: Command '['/home/deploy/test/bin/python3', '-Im', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1.
operating from the miniconda directory at ~/miniconda3/bin (screenshot). How can I this working?
edit:
deploy#server:~/miniconda3/bin$ /home/deploy/test/bin/python3 -Im ensurepip --upgrade --default-pip
/home/deploy/test/bin/python3: No module named ensurepip
If you are using anaconda, you should be using conda environments.
conda create --name test
For more information, see Managing Environments.
EDIT In response to OP wanting to use virtualenvs.
The error is with python not being able to find pip. You can get around this by installing it manually.
python3 -m venv test --without-pip
cd test
source bin/activate
curl https://bootstrap.pypa.io/get-pip.py | python3
At this point you will have a basic virtualenv with pip installed.

I am trying to install venv but getting this error:
name#malikov:~/Desktop/informtech$ python3 -m venv venv
Error: Command '['/home/name/Desktop/informtech/venv/bin/python3', '-Im', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1.
venv folder created but there is no activate file to activate venv
What should I do. Is there any solution. All problems started after upgrading python version from 3.8 to 3.10strong text
You can try installing venv for python3.10 via command:
sudo apt install python3.10-venv
In the interest of not getting an XY problem: the goal is to create a virtual environment on synology dsm, so no apt-get, where pip is installed manually.
I am trying to create a virtual environment, in above environment (synology dsm package python 3.8 with pip installed manually).
However this gives the following error:
$ python3 -m venv new_venv
Error: Command '['/volume1/docker/builder/new_venv/bin/python3', '-Im', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1.
In the chain of finding that error I discovered that venv is working "just fine":
$ python3 -m venv --without-pip new_venv
Works as expected. Also pip itself works as expected. However I had to install pip manually. This also has as consequence that the synology dsm version of python does not have the module ensurepip..
# python3 -c "import ensurepip; print(ensurepip.__file__);"
Traceback (most recent call last):
File "<string>", line 1, in <module>
ModuleNotFoundError: No module named 'ensurepip'
This gives the problem: how does one manually install ensurepip, and/or make virtual env install pip without relying on ensurepip?
Install pip inside your venv virtual environment
Download the newest pip installation script and name the file get-pip.py:
$ curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
Create the virtual environment with Python 3 but without pip inside it (assuming you are in /volume1/docker/builder/):
$ python3 -m venv --without-pip /volume1/docker/builder/new_venv
Activate the virtual environment:
$ source /volume1/docker/builder/new_venv/bin/activate
Your prompt should now contain the virtual environment name in parens:
(new_venv) $
The script will install pip inside the activated venv virtual environment:
(new_venv) $ python get-pip.py
# or
(new_venv) $ python3 get-pip.py
I'm a complete beginner to Ubuntu and I'm trying to create a virtual environment on Ubuntu 18.04. I had one running and it was working just fine, but I don't know what I did and know I cant get it to run.
I deleted my old env/ file and now I'm trying to create a new one using
python3 -m venv env
but I get the following error
Error: Command '['/home/user/app/env/bin/python3', '-Im', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit s
tatus 1.
What gives?
Do you have the python3-venv package installed?
If not - install it with apt-get install python3-venv and try again python3 -m venv env
just reinstall your python3-venv
apt-get purge python3-venv
apt-get install python3-venv
and then create the virtualenv
python3.7 -m venv venvTest
if you have different version of python3, you should mention the exact python3 version.
you can also migrate your python3.6 to python3.7 by following guide migrate python3.6 to python3.7
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
I installed virtual env with sudo pip install virtualenv but when I run python -m venv flask I'm still getting this: /usr/bin/python: No module named venv
Versions, if that's relevant:
pip 1.5.6 from /usr/lib/python2.7/dist-packages (python 2.7)
Python 2.7.9
what am I missing here?
Since you are on Python 2, you need to execute using the virtualenv module that you installed.
First step, as you originally tried to do, but this time you specify the "virtualenv" module and the name of the virtualenv. In this case flask:
python -m virtualenv flask
Then you activate your virtualenv like this:
source flask/bin/activate
Then install flask with pip inside the virtualenv
pip install flask
If you want to deactivate your virtualenv, simply type:
deactivate
If running on Python 3, the venv command is built-in and you can simply do:
python3 -m venv flask
Note, depending on how your Python 3 is installed, your python execution command might differ. You could be running it as python3, python3.5, python3.6.
venv is a module introduced in python3
venv is New in version 3.3.
The venv is ony available in python 3 version. If you are using python 2 then try to use virtualenv instead of venv.
1. Install virtualenv,
python -m pip install virtualenv
2. Create a virtual environment named venv using virtualenv,
Python 2
python -m virtualenv venv
Python3
python -m venv venv
3. Activate virtual environment,
.\venv\Scripts\activate.bat
4. Install flask package,
pip install flask
If are you using "windows".
Try it in "cmd"
navigate in cmd to the folder you want to install venv and do:
python3 -m venv project_env
You can change the name of the project to.
I changed python -> python3:
python3 -m venv flask
For python3 users, just be sure that you installed pip and venv packages:
sudo apt install python3-pip
sudo apt install python3-venv
Then you can use it like this:
python3 -m venv ~/sample
. ~/sample/bin/activate
pip install flask
Do the following for this issue.
pip install venv
(If this has got some issue that means python version recognized by your machine don't have updated version) so use below command:
pip install the virtualenv
python -m venv <>
if this has got the same issue so use below one.
python -m virtualenv <>
sudo apt-get install python3-pip
python3 -m pip install virtualenv
python3 -m virtualenv venv
source venv/bin/activate
