VS Code automatically activating virtual environment - python

I was at first prompted to enter the virtual environment being used in my project by vs-code, and so I accepted.
Even though I'm now in a different project folder, it still tries to enter the non-existent virtual environment automatically (I clicked Don't show me again on the popup so it doesn't ask anymore). When I run a python program, the terminal runs the following command:
PS C:\WINDOWS\System32\WindowsPowerShell\v1.0> & "c:/filepath/virtual_env/Scripts/Activate.ps1"
and then I recieve this error:
& : File c:\filepath\virtual_env\Scripts\Activate.ps1 cannot be loaded because running scripts is disabled on this system. For more information, see
about_Execution_Policies at https:/go.microsoft.com/fwlink/?LinkID=135170.

How can I disable automatically activating the virtual environment?

The venv docs have a note about how to change your execution policy: Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser (requires Python 3.8, otherwise you need to use a different execution policy).
As for turning off automatic environment activation, "python.terminal.activateEnvironment": false will do it as covered by the environments docs for the Python extension point out.

How do I activate my virtual environment using PyCharm? Can I even activate it in PyCharm?

I have am slightly confused about the local and command prompt in the terminal section of PyCharm. Could someone explain to me what the differences are?
Also, how do i activate my virtual environment from PyCharm, as i need it to run selenium (i placed it in a separate virtual environment). Do I use command prompt or local. I tried using local and when i type activate.bat in my Scripts folder, I come across this error message:
activate.bat : The term 'activate.bat' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

Can someone assist me on how i can activate my virtual enviornment via PyCharm?
Yes, you can activate your virtual environment in Pycharm. Pycharm configures an interpreter for each project, and by default uses the system Python interpreter if not otherwise specified. To use the virtual environment's interpreter do the following:
Settings > Project > Python Interpreter
Click on the cog next to the path, and select Add... to add a new interpreter
Select existing environment, and enter the path of the venv
Click OK
After doing this Pycharm will do some indexing, and the next time you run your program it should run using that virtual environment.

Virtual Environment won't activate on Windows 10

I use Windows 10, python 3.7.4 and i've installed virtualenv with pip.
When i try to create virtual environment in cmd i can create with virtualenv myenv.It creates the files needed, Scripts folder and activate files are all there. But when i try to activate nothing happens. I try:
C:\Users\Spike\pyenv>cd crawler
C:\Users\Spike\pyenv\crawler>cd scripts
C:\Users\Spike\pyenv\crawler\Scripts>activate
After this virtual environment name should be in parenthesis like this:
(crawler) C:\Users\Spike\pyenv\crawler\Scripts
but it is not, virtual env is not activated, it continues like this:
C:\Users\Spike\pyenv\crawler\Scripts>
I've tried running cmd in admin mode, doesn't work.
I've tried to activate from Powershell:
PS C:\Users\Spike\pyenv\crawler> cd scripts
PS C:\Users\Spike\pyenv\crawler\scripts> activate
But i get a error:
activate : The term 'activate' is not recognized as the name of a cmdlet, function, script file, or operable program.
Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
At line:1 char:1
+ activate
+ ~~~~~~~~
+ CategoryInfo : ObjectNotFound: (activate:String) [], CommandNotFoundException
+ FullyQualifiedErrorId : CommandNotFoundException
So i've tried Set-ExecutionPolicy AllSigned and Set-ExecutionPolicy Unrestricted -Force on Powershell before activating it, it also doesn't work.
I've also tried to activate it in cmder, i get the same result i got in cmd.
To solve i first looked in to other stackoverflow thread but none helped.
Check the name of your virtualenv. You said the name of your env was myenv. However, you are in the pyenv directory. If you CD to the folder you where in when you created myenv, the following should work.
myenv/Sripts/activate
If that does not work, make sure the activate file is actually there.
Also, note that in certain cases the virtualenv starts but you don't get the (myenv) bahavior. Run the following to see if the virtualenv is activated.

How to setup a virtual environment for python in Visual Studio Code using the command line

I am a very new programmer trying to learn Flask now that I've learned the basics of Python. I am following this tutorial https://www.youtube.com/watch?v=Z1RJmh_OqeA&t=355s ... I am stuck at 5:46.
The tutorial, as well as documentation on several other websites, explains to type in the following command:\env\Scripts\activate.bat for Windows, and they suggest using:source env/bin/activate for Mac.
This is what I get in return:
\env\Scripts\activate.bat : The term '\env\Scripts\activate.bat' is not recognized as the name of a
cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was
included, verify that the path is correct and try again.

Suggestion [3,General]: The command \env\Scripts\activate.bat was not found, but does exist in the current location. Windows PowerShell does not load commands from the current location by default. If you trust this command, instead type: ".\\env\Scripts\activate.bat". See "get-help about_Command_Precedence" for more details.
Until this point everything else had gone smoothly.This is what I've done leading up to this point:
pip3 install virtualenv
virtualenv env
After running these commands, the tutorial asks me to run the command I'm having problems with.
What options do I have to fix this??
You probably have not set the path variable so the system can't find the Scripts folder. In a typical Python installation on Windows (which you seem to be using), Python is installed under the C drive in Program Files, and inside that directory is the Scripts directory, which is where virtualenv.exe lives.
So you need to open Control Panel, go to System, click on Advanced System Settings, click on Environment Variables, then under USER variables highlight Path, click on Edit, and see if the path to Scripts exists; it'll be something like:
C:\Program Files\Python37\Scripts
If it's not there you need to click New and enter it.
I think you should add . before the \env\... path. This implies that, instead \env\Scripts\activate.bat do .\env\Scripts\activate.
Moreover, you can navigate to the venv\Scripts\ folder and type activate.
copy this term and past your command line in your PyCharm and enter:
.\activate

virtualenv activate does not work

I am trying to create a virtual environment to test an api.
I can create the environment just fine using virtualenv test, then I can cd into it. When I try to run activate, I get this error:
PS C:\Users\Bright Bridge\Desktop\autocomplete_demo\Scripts> activate

I recently updated windows, and it replaced the cmd with Windows Powershell. My virtualenv worked fine with the cmd, so I suspect it may have to do with the way the Powershell does things.
How can I activate the virtualenv?
If you press WindowsKey + R, and type cmd when the box comes up, it should bring up the command line interface instead of powershell!
For those of you still interested, the output gives you the answer:
If you trust this command, instead type: ".\activate".
So use a relative path name to run the activate script in powershell, or use an absolute path
You need to set windows execution policies. According to official documentation of virtualenv.
Run in powershell Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUse
Now you can activate virtual env. using \Scripts\Activate.ps1
Hope it solves it!
Just Enter one PowerShell Command
.\Scripts\activate
Rather Then
./Scripts/activate
Execute .\activate instead of activate
That worked for me.
You basically needs to set execution policy for PowerShell
Step 1: Run PowerShell as Administartor
Step 2: Run Below Command
Set-ExecutionPolicy RemoteSigned
After successfull run, You will be able to activate vertual environemnt.
Enjoy :)
after jumping to Scripts folder
cd Scripts
just write .\activate
It works perfectly
On my windows I use this way with gitbash
cd .myenv/Scripts
then navigate and type
activate
works for me
first make virtualenv with virtualenv pymote_env
Activate environment: pymote_env\Scripts\activate
in your case:-
first make virtualenv with virtualenv test
Activate environment: test\Scripts\activate
http://pymote.readthedocs.io/en/latest/install/windows_virtualenv.html
Use command pompt instead of using power-shell
and run the same command
this should work
Instead of all variants it works with C:...venv\scripts .\activate.ps1
But before that, I changed my ExecutionPolicy to RemoteSigned. You can do it by next steps.
Enter Set-ExecutionPolicy
Enter RemoteSigned
System should ask you if u wish to save changes. Answer with "Y"
enter image description here
1.Just add the complete path in cmd like this " cd.\pyenvDjango\Scripts" and press enter,
Now you see the complete directory path in which you are.
Now just type ".\activate".
this will activate your env.
NOTE:- try this in cmd not in vs code terminal or any where

Virtualenvwrapper-win installed on Windows 10 but can't activate virtual environment

When I try to activate the virtual environment using the command workon <name>, the virtual environment does not activate. I am using a Windows 10 machine and installed Virtualenv, VirtualenvWrapper, and VirtualenvWrapper-win .
For example when I input lsvirtualenv into the command shell I can see that the <name> virtual environment exists but I can not activate it. Can you please help me?
edit #1:
When I try to activate the file directly I receive the following error from the terminal:
PS C:\users\stefan\envs\rango\scripts> .\activate .\activate : File C:\users\stefan\envs\rango\scripts\activate.ps1 cannot be loaded. The contents of file C:\users\stefan\envs\rango\scripts\activate.ps1 might have been changed by an unauthorized user or process, because the hash of the file does not match the hash stored in the digital signature. The script cannot run on the specified system. For more information, run Get-Help about_Signing..

EDIT 2 -
I was able to get it to work by running powershell as administrator and changing the execution policy to "remotesigned". See below for method:
If the current console is not elevated and the operation you're trying to do
requires elevated privileges then you can start powershell with the "Run as administrator"
option:
PS> Start-Process powershell -Verb runAs
The current execution policy may be identified using the Get-ExecutionPolicy cmdlet:
PS C:\Users\Administrator> get-executionpolicy
In order to change the prevailing execution policy, the Set-ExecutionPolicy cmdlet is
used in conjunction with the new execution policy setting. For example, to change to
RemoteSigned, the following command should be executed:
PS C:\Users\Administrator> set-executionpolicy remotesigned
Execution Policy
Description
Restricted The default policy on Windows PowerShell, this mode disables the execution of script files. Windows PowerShell may only be used by manually issuing commands at the command prompt.
AllSigned Limits execution to scripts which are authenticode signed. When a signed script is executed, PowerShell will prompt for confirmation that the signer of the script can be trusted.
RemoteSigned Requires that any scripts that have been downloaded from a remote location must be signed before they may are permitted to execute.
Unrestricted Allows any script to be executed, regardless of origin or whether it is signed.
From the virtualenv docs, one possible solution would be to relax the system execution policy to allow running of local scripts without verifying the code signature.
To do that, run powershell as an administrator, cd to your C:> directory and type the following command:
PS C:\> Set-ExecutionPolicy RemoteSigned
