'virtualenv' won't activate on Windows

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?

Instead of using the Powershell for the terminal use Command Prompt and that solved my issue.

This worked for me:

To activate a Python virtual environment in Visual Studio Code's PowerShell terminal without needing administrator rights, navigate to the script's directory and execute::

powershell.exe -executionpolicy unrestricted -command .\Activate.ps1 -Scope CurrentUser

Then, use the activate command. This approach temporarily permits running the specified script for the current user only.

Note: This will only allow that specific script to run, and only by the user you are currently signed in with.

Create a .bat script:

call .\env\Scripts\deactivate
RMDIR /Q/S env

call python -m pip uninstall pip -y
call python -m ensurepip
call python -m pip install --upgrade pip
call python -m pip install --user virtualenv
call python -m virtualenv env

call .\env\Scripts\activate

# Install pip requirements
call python -m pip install --upgrade pip
call python -m pip install Pillow

# Run main scripts here
call python main.py

call .\env\Scripts\deactivate

Run this script via Command Prompt.

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

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.

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.

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!

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.

On Windows, open Windows PowerShell as Administrator

Enter image description here

Set-ExecutionPolicy Unrestricted -Force

Create a virtual environment:

pip install virtualenv
virtualenv foo
cd .\foo
.\Scripts\activate

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

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.

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

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.

To install a virtual environment in Windows PowerShell only, but to activate, you'll need to run Windows PowerShell as an Administrator:

  1. pip install virtualenv
  2. virtualenv %Name of virtual environment%

It is installed now to activate it. Run PowerShell in as an administrator

  1. Set-ExecutionPolicy Unrestricted -Force
  2. .\env\Scripts\activate

To deactivate the environment

  1. .\env\Scripts\deactivate

For more help, do visit the official page: https://pypi.org/project/virtualenv/1.8.2/

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.

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.

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.
