virtualenv won't activate on windows

Question

Essentially I cannot seem to activate my virtualenv environment which I create.

I\'m doing this inside of windows powershell through using

scripts\\a         


        

Answer 1

In powershell use

Scripts\activate.ps1

instead of activate.bat which doesn't work in powershell anymore.

also deactivate by just typing

deactivate

at the command prompt

Answer 2

If machine a 64 bit, open the x86 instance of PowerShell as Administrator & check (set) the execution policy. try this

Set-ExecutionPolicy Unrestricted

or

Set-ExecutionPolicy Unrestricted -Force

Answer 3

Based on the answers found here, I created a short tutorial for this with screenshots.

• Python 3.7
• Windows 10 64bits
• PowerShell

Hope it can help: https://github.com/harrywang/self-contained-project/wiki/How-to-setup-Python-3-virtual-environment-on-Windows-10

Answer 4

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

Answer 5

This worked for me:

You can simply open a normal (you do not need elevated access) cmd or powershell session (I use the embedded PS terminal in vscode) 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.

Answer 6

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.
