Issue with virtualenv - cannot activate

Python Problem Overview

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 source venv/bin/activate

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

Python Solutions

Solution 1 - Python

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 venv\Scripts\activate instead (per the virtualenv documentation on the activate script).

Just run activate, without an extension, so the right file will get used regardless of whether you're using cmd.exe or PowerShell.

Solution 2 - Python

I was also facing the same issue in my Windows 10 machine. What steps i tried were:

Go to andconda terminal Step 1

pip3 install -U pip virtualenv

Step 2

virtualenv --system-site-packages -p python ./venv

virtualenv --system-site-packages -p python3 ./venv

Step 3

.\venv\Scripts\activate

You can check it via spider tool in anaconda by typing import tensorflow as tf

Solution 3 - Python

I had the same problem. I was using Python 2, Windows 10 and Git Bash. Turns out in Git Bash you need to use:

 source venv/Scripts/activate

Solution 4 - Python

For activation you can go to the venv your virtualenv directory by cd venv.
Then on Windows, type dir (on unix, type ls). You will get 5 folders include, Lib, Scripts, tcl and 60
Now type .\Scripts\activate to activate your virtualenv venv.

Your prompt will change to indicate that you are now operating within the virtual environment. It will look something like this (venv)user@host:~/venv$.

And your venv is activated now.

Solution 5 - Python

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:

> .\env\Scripts\activate

Solution 6 - Python

For windows, type "C:\Users\Sid\venv\FirstProject\Scripts\activate" in the terminal without quotes. Simply give the location of your Scripts folder in your project. So, the command will be location_of_the_Scripts_Folder\activate.

Solution 7 - Python

source command is officially for Unix operating systems family and you can't use it on windows basically. instead, you can use venv\Scripts\activate command to activate your virtual environment.

$Made a Screenshot of how venv\Scripts\activate command works correctly$

Solution 8 - Python

Open your powershell as admin
Enter "Set-ExecutionPolicy RemoteSigned -Force
Run "gpedit.msc" and go to >Administrative Templates>Windows Components>Windows Powershell
Look for "Activate scripts execution" and set it on "Activated"
Set execution directive to "Allow All"
Apply
Refresh your env

Solution 9 - Python

if you already cd your project type only in windows 10

Scripts/activate

That works for me:)

Solution 10 - Python

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 #!./.env/Scripts/python.exe;

Both assuming your working directory contains your virtualenv (.env).

Solution 11 - Python

You can run the source command on cygwin terminal

Solution 12 - Python

A small reminder, but I had my slashes the wrong way on Win10 cmd. According to python documentation the activate command is: C:\> <venv>\Scripts\activate.bat When you're browsing directories it's e.g. cd .env/Scripts

So to create my venv I used python -m venv --copies .env and to activate .env\Scripts\activate.bat

Solution 13 - Python

open the folder with any gitbash console. for example using visualCode and Gitbash console program: 1)Install Gitbash for windows

using VisualCode IDE, right click over the project open in terminal console option
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

Solution 14 - Python

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

Solution 15 - Python

Finally Worked on Windows 10 by using:

activate myvenv

where myvenv is the name the virtual environment I want to activate.

So basically, the command is:

activate <<your_venv_name>>

All the best!

Solution 16 - Python

If you see the 5 folders (Include,Lib,Scripts,tcl,pip-selfcheck) after using the virtualenv yourenvname command, change directory to Scripts folder in the cmd itself and simply use "activate" command.

Solution 17 - Python

If wants to open virtual environment on Windows then just remember one thing on giving path use backwards slash not forward.

This is right:

D:\xampp\htdocs\htmldemo\python-virtual-environment>env\Scripts\activate

This is wrong:

D:\xampp\htdocs\htmldemo\python-virtual-environment>env/Scripts/activate

Solution 18 - Python

Tried several different commands until I came across:

source venv/Scripts/activate

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.

Solution 19 - Python

Windows 10 using Git Bash.

cd Scripts

. activate

Solution 20 - Python

The steps for activating virtualenv using Python3 on windows are:

python3 -m venv env
.\env\bin\activate

Solution 21 - Python

If you’re using Windows, use the command "venv\Scripts\activate" (without the word source) to activate the virtual environment. If you’re using PowerShell, you might need to capitalize Activate.

Solution 22 - Python

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.

Solution 23 - Python

Open your project using VS code editor .
Change the default shell in vs code terminal to git bash.
now your project is open with bash console and right path, put "source venv\Scripts\activate" in Windows

Solution 24 - Python

Navigate to your virtualenv folder eg ..\project1_env> Then type

> source scripts/activate

eg ..\project1_env>source scripts/activate

Solution 25 - Python

If some beginner, like me, has followed multiple Python tutorials now possible has multiple Python versions and/or multiple versions of pip/virtualenv/pipenv...

In that case, answers listed, while many correct, might not help.

The first thing I would try in your place is uninstall and reinstall Python and go from there.

Solution 26 - Python

The best way is, using backward slahes and using .bat at the end of activate

C:\Users>your_env_name\Scripts\activate.bat

Solution 27 - Python

:: location of bat file
::C:\Users\gaojia\Dropbox\Projects\free_return\venv\Scripts\activate.bat 
:: location of the cmd bat file and the ipython notebook
::C:\Users\gaojia\Dropbox\Projects\free_return\scripts\pre_analysis
source ..\..\venv\Scripts\activate
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?

Solution 28 - Python

If you are using windows, just run .\Scripts\activate. Mind that the backslash plays the trick!

Solution 29 - Python

For python 3.8 and above, following code will work. Make sure to start with 'source'

source your_environment_name/Scripts/activate

Solution 30 - Python

Use These it worked for meenv\Scripts\activate

Solution 31 - Python

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:

> venv/Scripts/activate

Solution 32 - Python

if .\venv\Scripts\activate 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

Solution 33 - Python

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 :)

Solution 34 - Python

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.
