I'm trying to create and activate a virtual environment, using Windows 10 command prompt. I know that virtualenv is installed correctly, as the command
virtualenv venv
Works. I've navigated to my virtualenv download, Downloads\venv\Scripts, and am trying to activate my virtual environment venv. I've tried
venv activate
Which doesn't work since Windows doesn't recognize venv as a command. I've also tried
virtualenv venv activate
Which also doesn't work since virtualenv is saying that "venv activate" isn't a valid argument.
Use the activate script in the Scripts directory of your virtual environment:
> venv\Scripts\activate
This will activate your virtual environment and your terminal will look like this depending on the directory you're in:
(venv) C:\Users\acer\Desktop>
I hope this helps!
If you're using virtualenvwrapper-win, and using the DOS command prompt (as opposed to e.g. Powershell), then new virtualenvs are created using:
mkvirtualenv myenv
and activated using
workon myenv
You should define the environment variable WORKON_HOME to point to where you want you virtualenvs to reside.
If you've installed virtualenvwrapper-win>=1.2.4 then the virtualenvwrapper command will give you a list available commands:
go|c:\srv> virtualenvwrapper
virtualenvwrapper is a set of extensions to Ian Bicking's virtualenv
tool. The extensions include wrappers for creating and deleting
virtual environments and otherwise managing your development workflow,
making it easier to work on more than one project at a time without
introducing conflicts in their dependencies.
virtualenvwrapper-win is a port of Dough Hellman's virtualenvwrapper to Windows
batch scripts.
Commands available:
add2virtualenv: add directory to the import path
cdproject: change directory to the active project
cdsitepackages: change to the site-packages directory
cdvirtualenv: change to the $VIRTUAL_ENV directory
lssitepackages: list contents of the site-packages directory
lsvirtualenv: list virtualenvs
mkproject: create a new project directory and its associated virtualenv
mkvirtualenv: Create a new virtualenv in $WORKON_HOME
rmvirtualenv: Remove a virtualenv
setprojectdir: associate a project directory with a virtualenv
toggleglobalsitepackages: turn access to global site-packages on/off
virtualenvwrapper: show this help message
whereis: return full path to executable on path.
workon: list or change working virtualenvs
From the directory where you have your virtual environment (e.g. myenv)
you need to run the following command: .\myenv\Scripts\activate
Go to the folder where you have created the virtual environment in cmd and
enter the command .\venv\Scripts\activate
It will activate the virtual env in windows
from the command (cmd) prompt:
call venv/Scripts/activate
Make sure the Python Scripts folder is in your environment variables.
Usually the path is: "C:\Users\admin\AppData\Local\Programs\Python\Python37-32\Scripts"
(Change "admin" to your windows username and "Python37-32" path according to your python version)
When you use "virtualenv" to create an env, it saves an "activate.bat" file in the scripts folder originating from the directory you ran the first command. E.g if you ran the command virtualenv env from C:/Users/Name/Documents/..., the .bat will be located in C:/Users/Name/Documents/.../env/scripts/activate.bat. You can run it from there.
Simply you can activate your virtualenv using command: workon myenvname
You can also create a command-line script like this -
#echo off
CD\
CD "C:\Users\[user name]\venv\Scripts"
start activate.bat
start jupyter notebook
Save this in a notepad file with an extension ".cmd".
You are ready to go
if you have anaconda installed then open anaconda terminal and type
> conda env list # for list of environment you already have
> conda activate {env_name} # to activate the environment
This works for me from Anaconda prompt,
.\\myvenv\\Scripts\\activate.bat
start python 3.7
python -m virtualenv
"You must provide a DEST_DIR"
python -m venv demodjango("demodjango is file name)"
activate.bat
pip install django
django-admin.py startproject demo1 (demo1 is my project)
python manage.py runserver
Performing system checks...
After doing this on a command prompt, you will get an URL. Click on that and you will see a message in the browser window that Django has been properly installed.

I am just starting to learn django and I am facing the set-up phase. In particular I'd like to ask how to recognize if the virtual environment is activated or not. I know that I can use the command pip freeze but in all the tutorial that I am following, when the venv is activated, I can see the venv name in brackets in the terminal command line.
I can correctly activate the venv with the source command and check via the pip freeze command but I have no indication in the command line.
I am on a Mac/OS(M1) and using python3
thank you
To have visual information about the virtualenv on the command line you need to change the shell config to show it. It's not related to python or django itself.
It will depend on the shell that you are using, but assuming the default shell on mac you can check this question virtualenv name not show in zsh prompt
From venv docs.
When a virtual environment is active, the VIRTUAL_ENV environment variable is set to the path of the virtual environment. This can be used to check if one is running inside a virtual environment.
So you should be able to test it with:
import os
os.getenv('VIRTUAL_ENV') is not None
Yes, when the virtual environment is activated, it shows in the terminal as a prefix like
(env) yourname~Desktop/workspace-folder>
And that is enough to know it is activated, and you are using it.
Since you are using Python 3, you can create your virtual environment as follows in the same directory of your project, open terminal or iTerm and run this comman
python3 -m venv env
After few seconds, a folder env will be created that is your virtual environment. Note you can name your virtual environment as you wish, maybe like python3 -m venv djang-app
After you have created the virtual environment, you can now activate it like
source env/bin/activate
Again, if you created your virtual environment using lets say django-app
python3 -m venv django-app
You can activate it like this
source django-app/bin/activate
and you will see your terminal is prefixed as follows
(django-app) yourname~Desktop/workspace-folder>
To deactivate the virtual environment, you simply run this command deactivate in the terminal with active virtual environment.
You can learn more about python3 venv from here.
So I installed venv for python and made a virtual environment called ftai_venv. However when I activate it I get an error
When I go into ftai_venv/bin, I don't see the activate bash file. Where would I get this?
The file should be there have you tried creating another virtual environment ?
Run below commands to create the virtual environment
On macOS and Linux:
python3 -m venv ftai_venv
source ftai_venv/bin/activate
for more detail check the link
When using Pycharm, I make my virtual environment when I m creating a new project and then never have to think about activating it or anything. It works just fine.
When I m using the terminal on my Mac OS, I need to create the virtual environment and then also activate it.
I also have to activate it for VS Code.
How do I know when I need to activate my virtual environment? Thanks.
To activate a virtual environment from the terminal, you need to source a file that the venv module created. This file typically will be in the bin directory of your project (ej. my_project/folder/bin) and will be named activate.
So to activate the environment in your shell you would run the command
source my_project/folder/bin/activate
You should know if you're already IN the virtual environment, when you see the project's name parsed to some part of your shell prompt. If you're already into your virtual environment, you can leave it with the deactivate command.
Could anyone please help me with how to fix the virtuaenv issue on windows 10 - 64-bit pc. I repeatedly keep getting this error while I try to create a virtual env using windows Powershell/Command windows to install Django projects
Error message "mkvirtualenv : The term 'mkvirtualenv' is not recognized as the name of a cmdlet, function, script file, or operable
program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again."
Appreciate your advice
First thing first, create a new folder or directory where you want to create your virtual environment. Once done locate that folder through CMD prompt.
Now, To create virtual environment in command prompt you first need to create a virtual environment wrapper first and with the help of that you can create virtual environment. Make sure you have python in your system before following below steps, type these commands one by one in your CMD prompt:
pip install virtualenvwrapper-win
mkvirtualenv name
note: in second code you can choose any name for your virtual environment
note: You will see something like this in your CMD prompt (name) C:\Users....
now install django in this virtual environment, just type the following command
pip install django
All done !
Extras (optional)
To check django version:
django-admin --version
(Type this command in your virtual environment only)
To work again on the same virtual environment:
workon name
( In place of enter the name of your virtual environment)
To stop virtual environment:
deactivate
( Yup, only this one code)
And then exit, happy coding :)
The package which will provide "mkvirtualenv" has not been installed on your computer or your computer cannot locate where it is.
These packages below should be installed:
pip install virtualenv
pip install virtualenvwrapper-win
i also got the same problem and this how i managed to overcome it
1- specify a directory/folder where you are to store the project using cmd ie for windows
create a folder eg on desktop to store the project
C:\Users\zack>cd desktop
create a virtual environment folder on desktop using venv in the terminal
C:\Users\zack\Desktop>py -m venv django_project
activate the virtual environment using scripts\activate.bat
C:\Users\zack\Desktop>django_project\scripts\activate.bat
you will see the virtual environment project on the desktop as shown below
(django_project) C:\Users\zack\Desktop>
at the end a virtual environment folder is created on the desktop
I wanted to create a python virtual environment in Windows 7.
I have installed activepython 2.7 32 bit version and installed virtualev using pip command. After that I created a folder named "virtualenv", on drive C. For that folder I have executed the following command.
virtualenv <virtualenv-name>
While executing this command it opens a python file named virtualenv.py. While closing the file, it does not prompt to be saved.
While checking on C:\virtualenv\ I was not getting the virtual environment that I tried to create.
From command line execute:
virtualenv MY_ENV
It will create a virtual env in MY_ENV folder. Than activate it:
MY_ENV\Scripts\activate
Also check the virtualenv user guide.
conda create --name myvirtualenv python=2.7 numpy
This will create a virtual environment of python 2.7 with just numpy or pandas or the full package based on the parameter
First, open cmd and go to the directory where you want your virtual env to be present.
while writing this I have 3.7.5 python installed on my PC.
write below command on cmd.
py -m venv.
for activation of the virtual environment.
open Scripts folder and click on activate file,
