'virtualenv' won't activate on Windows
PythonVirtualenvPython Problem Overview
Essentially I cannot seem to activate my virtualenv environment which I create.
I'm doing this inside of Windows PowerShell through using
scripts\activate
but I get an error message:
> "cannot be loaded because the execution of scripts is disabled on this > system".
Could this be because I don't carry administrator privileges on my computer?

Solution 1 - Python
According to Microsoft Tech Support it might be a problem with Execution Policy Settings. To fix it, you should try executing Set-ExecutionPolicy Unrestricted -Scope Process (as mentioned in the comment section by @wtsiamruk) in your PowerShell window. This would allow running virtualenv in the current PowerShell session.
There is also another approach that is more unsafe, but recommended by MS Tech Support. This approach would be to use Set-ExecutionPolicy Unrestricted -Force (which do unleash powers to screw Your system up). However, before you use this unsafe way, be sure to check what your current ExecutionPolicy setting is by using get-ExecutionPolicy. Then, when you are done, you can revert back to this ExecutionPolicy by using Set-ExecutionPolicy %the value the get-ExecutionPolicy command gave you% -Force.
Solution 2 - Python
In PowerShell use
Scripts\activate.ps1
instead of activate.bat which doesn't work in PowerShell any more.
Also deactivate it by just typing
deactivate
at the command prompt.
Solution 3 - Python
On Windows, open Windows PowerShell as Administrator
Set-ExecutionPolicy Unrestricted -Force
Create a virtual environment:
pip install virtualenv
virtualenv foo
cd .\foo
.\Scripts\activate
Solution 4 - Python
Set the excution policy for the process scope. After Yes [y], type the script/activate:
Solution 5 - Python
Open another PowerShell window as administrator and then type:
set-executionpolicy remotesigned
Then press Y and then Enter.
Now close this PowerShell window and go back to the shell you were working with. This will solve the issue.
Solution 6 - Python
Another quick solution I have found here (it is applicable for Windows PowerShell only) is like this:
First run
Scripts\cmd
Then run
Scripts\activate.bat
At this position, your Virtualenv is activated. Now if you deactivate it and want to activate it again later in the same session of PowerShell, you just need to run:
Scripts\activate
There isn't any need to use cmd or activate.bat command later.
Solution 7 - Python
Follow these steps to the letter.
Step 1. Use Windows PowerShell as ADMINISTRATOR. (VERY IMPORTANT) and cd into the project folder. Run
virtual env
Step 2. Check in the scripts folder if you have your activate.bat file
\env\Scripts\activate.bat # It has to be there.
Step 3. If it is not, here make sure you have an Internet connection and run this again
virtual env
step 4. If the activate.bat file is there in the script folder, proceed.
step 5. Run this in your shell:
Set-ExecutionPolicy Unrestricted -Force
Step 6. To activate virtualenv on Windows, activate script is in the Scripts folder:
env\Scripts\activate.bat
Step 7. Check for the (env) at the start of each line. This shows you are on the virtual environment.
Step 8. To reactivate when you come back to the project the second time, run:
.\\env\Scripts\activate
Solution 8 - Python
To install a virtual environment in Windows PowerShell only, but to activate, you'll need to run Windows PowerShell as an Administrator:
pip install virtualenvvirtualenv %Name of virtual environment%
It is installed now to activate it. Run PowerShell in as an administrator
- Set-ExecutionPolicy Unrestricted -Force
.\env\Scripts\activate
To deactivate the environment
.\env\Scripts\deactivate

Solution 9 - Python
If you don't want to change your computer's execution policy on Windows like I do, you can use a Windows command prompt instead of Windows PowerShell and just need to run
`Scripts\activate`
to activate your environment.
Solution 10 - Python
For me on Windows 10 64 bit:
- Open cmd as an Administrator
powershell- Type
Set-ExecutionPolicy Unrestricted -Force
Voilà, reopen Visual Studio Code and start pythoninnngg.
Solution 11 - Python
Below steps are working -
- Set python path like C:\Program Files\Python310\Scripts\ in Environment Variable
- Open PowerShell in Admin mode , and execute the below command -
Set-ExecutionPolicy Unrestricted -Force - Close PowerShell and repoen in Admin mode
- Execute the below command -
venv\scripts\activate
Solution 12 - Python
In Windows you should activate the virtual environment by the following command in cmd
> E:\your_environment\Scripts> activate.bat
If the environment is activated then it shows your environment name enclosed with a bracket like this:
> (your_environment) E:\your_environment\Scripts>
Also we can ensure by checking with where.exe it will list our active Python environment with order of hierarchy
(your_environment) E:\your_environment\Scripts>where.exe python
E:\your_environment\Scripts\python.exe
C:\Python27\python.exe
If you need to deactivate then do:
> (your_environment) E:\your_environment\Scripts>deactivate.bat
Solution 13 - Python
This worked for me:
You can simply open a normal (you do not need elevated access) cmd or PowerShell session (I use the embedded PowerShell terminal in Visual Studio Code) and type the following from the folder where the script file is, e.g.: .venv\Scripts\Activate.ps1:
powershell.exe -executionpolicy unrestricted -command .\Activate.ps1 -Scope CurrentUser
And then you can run the activate command after that.
Note: This will only allow that specific script to run, and only by your logged-in user.
Solution 14 - Python
If the machine 64 bit, open the x86 instance of PowerShell as Administrator and check (set) the execution policy.
Try this
Set-ExecutionPolicy Unrestricted
or
Set-ExecutionPolicy Unrestricted -Force
Solution 15 - Python
Based on the answers found here, I created a short tutorial for this with screenshots.
- Python 3.7
- Windows 10 64bits
- PowerShell

Solution 16 - Python
Delete the directory for that venv you created. And create a new one using the command:
python -m venv myvenv
Then see if the activate command works.
Solution 17 - Python
C:\path> Set-ExecutionPolicy - Scope CurrentUser
> cmdlet Set-ExecutionPolicy at command pipeline position 1 Supply values for the following parameters: ExecutionPolicy: Unrestricted
C:\path> Scripts\activate.ps1
(new env)
C:\path> deactivate
C:\path>
This worked.
Solution 18 - Python
In Windows PowerShell the ExecutionPolicy is set to 'restricted' by default. This does not allow scripts to be run in PowerShell.
We can only run scripts when the ExecutionPolicy is set to 'RemoteSensing' from 'Restricted' You can follow the video "PowerShell 08 - Changing the execution policy so you can run scripts" to do that!
After the above step, you can directly type "Scrits/activate" (while being in the directory of the virtual environment that you want to activate) to activate the virtual environment that you wish to activate!
Solution 19 - Python
If you have used pipenv in creating your virtual environment, you should run pipenv shell before executing any command in the Visual Studio Code terminal.
