I created a virtualenv around my project, but when I try to activate it I cannot.
It might just be syntax or folder location, but I am stumped right now.
You can see below, I create the virtualenv and call it venv. Everything looks good, then I try to activate it by running
I’m thinking it might just have to do with my system path, but not sure what to point it to (I do know how to edit the path). I’m on python 7 / windows os, virtual env 2.2.x

source is a shell command designed for users running on Linux (or any Posix, but whatever, not Windows).
On Windows, virtualenv creates a .bat/.ps1 file, so you should run
venvScriptsactivate instead (per the virtualenv documentation on the activate script).
activate, without an extension, so the right file will get used regardless of whether you’re using cmd.exe or PowerShell.
I have a hell of a time using
virtualenv on windows with git bash, I usually end up specifying the python binary explicitly.
If my environment is in say
.env I’ll call python via
./.env/Scripts/python.exe …, or in a shebang line
Both assuming your working directory contains your virtualenv (
For activation you can go to the
venv your virtualenv directory
Then on Windows, type
dir (on unix, type
You will get 5 folders
tcl and 60
.Scriptsactivate to activate your virtualenv
Your prompt will change to indicate that you are now operating within the virtual environment. It will look something like this
venv is activated now.
You can run the source command on cygwin terminal
I had the same problem. I was using Python 2, Windows 10 and Git Bash. Turns out in Git Bash you need to use:
A small reminder, but I had my slashes the wrong way on Win10 cmd. According to python documentation the activate command is:
When you’re browsing directories it’s e.g.
So to create my venv I used
python -m venv --copies .env and to activate
If you see the 5 folders (
pip-selfcheck) after using the
virtualenv yourenvname command, change directory to
Scripts folder in the cmd itself and simply use “activate” command.
I was also facing the same issue in my Windows 10 machine.
What steps i tried were:
Go to andconda terminal
pip3 install -U pip virtualenv
virtualenv --system-site-packages -p python ./venv
virtualenv --system-site-packages -p python3 ./venv
You can check it via spider tool in anaconda by typing
import tensorflow as tf
If you’re using Windows, use the command “venvScriptsactivate” (without the word source) to activate the virtual environment. If you’re using PowerShell, you might need to capitalize Activate.
If you are using windows OS then in Gitbash terminal use the following command $source venv/Scripts/activate. This will help you to enter the virtual environment.
open the folder with any gitbash console.
for example using visualCode and Gitbash console program:
1)Install Gitbash for windows
2) using VisualCode IDE, right click over the project open in terminal console option
3) on window console in Visualcode, looking for a Select->default shell and change it for Gitbash
4)now your project is open with bash console and right path, put source ./Scripts/activate
btw : . with blank space = source
Change the default shell in vs code terminal to git bash.
now your project is open with bash console and right path, put
“source venvScriptsactivate” in Windows
Navigate to your virtualenv folder eg
Ensure venv is there and just follow the commands below. It works in Windows 10.
Go to the path where you want your virtual enviroments to reside:
> cd <my_venv_path>
Create the virtual environment named “env”:
> python -m venv env
Add the path to the git ignore file (optional):
> echo env/ >> .gitignore
Activate the virtual env:
if you already cd your project type only in windows 10
That works for me:)
The best way is, using backward slahes and using .bat at the end of activate
:: location of bat file ::C:UsersgaojiaDropboxProjectsfree_returnvenvScriptsactivate.bat :: location of the cmd bat file and the ipython notebook ::C:UsersgaojiaDropboxProjectsfree_returnscriptspre_analysis source ....venvScriptsactivate PAUSE jupyter nbconvert --to html --execute consumer_response_DID.ipynb PAUSE
Above is my bat file through which I try to execute an ipython notebook. But the cmd window gives me nothing and shut down instantly, any suggestion why would this happen?
If wants to open virtual environment on Windows then just remember one thing on giving path use backwards slash not forward.
This is right:
This is wrong:
Tried several different commands until I came across:
This did it for me. Setup: Win 10, python 3.7, gitbash. Gitbash might be the culprit for not playing nice with other activate commands.
If you are using windows, just run .Scriptsactivate. Mind that the backslash plays the trick!
For windows Microsoft Tech Support it might be a problem with Execution Policy Settings. To fix it, you should try executing
Set-ExecutionPolicy Unrestricted -Scope Process
Finally Worked on Windows 10 by using:
myvenv is the name the virtual environment I want to activate.
So basically, the command is:
All the best!
The steps for activating virtualenv using Python3 on windows are:
Use These it worked for me
It’s been a while without usign Django, so when I got back to my old project I run into the same issue on Windows 10
and this worked for me:
Some people are having trouble with vscode i assume as all the above methods dont work.
Its simply because by default vscode uses powershell not cmd…
click on the little arrow beside it and select cmd and run the command.
.venvScriptsactivate does not work neither and you find this error
Activate.ps1 cannot be loaded because running scripts is disabled on this system
you can simple type
set-executionpolicy remotesigned in powershell and the error must be gone.
powershell should run as administrator
Open powershell as admin and paste this "set-executionpolicy remotesigned", then go back to where you tried to run the activate of the venv and it should work 🙂
Link to the article that explains more in detail:
For those of you crazy enough to have a custom DOS prompt, venv activation may fail, depending on your
%PROMPT% environment variable content.
Say you have a DOS prompt defined as follows:
set PROMPT=$_$E[1;30;40m[$E[0;36;40m%computername% | %userdomain%%username%$E[1;30;40m] $E[0;33;40m$M$_$E[35;40m$d$s$t$h$h$h$h$h$h$_$E[1;33;40m$p$_$E[1;30;40m$g $E[0;37;40m
(btw, it shows as follows, with some fancy colors:
[W10-MY_COMPUTER | W10-MY_COMPUTERJOHNDOE] 15/09/2022 20:31 F: > echo "Hello World" Hello World [W10-MY_COMPUTER | W10-MY_COMPUTERJOHNDOE] 15/09/2022 20:31 F: >
Then if you try to activate a venv :
it may fail with a rather unclear error that states:
Path not found
without further indications.
The trick is that
deactivate.bat) scripts try to save(/restore) the
%PROMPT% variable with this syntax:
... set _OLD_VIRTUAL_PROMPT=%PROMPT% ... set PROMPT=(venv) %PROMPT% ...
It can be fixed with this syntax:
... set "_OLD_VIRTUAL_PROMPT=%PROMPT%" ... set "PROMPT=(venv) %PROMPT%" ...
now it shows:
[W10-MY_COMPUTER | W10-MY_COMPUTERJOHNDOE] 15/09/2022 20:31 F: > venvScriptsactivate.bat (venv) [W10-MY_COMPUTER | W10-MY_COMPUTERJOHNDOE] 15/09/2022 20:31 F: >
Instead of using:
Your Script will be activated.
