How can I activate my virtual environment in visual code terminal? I've tried using the workspace settings method but the settings file was empty
If you have already created your virtual environment, you can just go to its directory by running the following in the VS Code terminal:
cd /python_env/bin/
and then
source ./activate
or, you can directly run
source ./python_env/bin/activate
from your main project directory.
Please follow the steps below:
Open your project folder in VS Code
Create a new terminal
Use the following command in the terminal to create a new virtual environment
# .venv is your virtual environment name
# You can also use py -3 -m venv .venv
python -m venv .venv
After the virtual environment is generated, use the following command to activate the virtual environment
# .venv is your virtual environment name
.venv\scripts\activate
Normally, when VS Code notices that you have created a new virtual environment, a popup will prompt you to allow it to be selected for the workspace.

I have no idea whats going on but I activated venv by using Scripts/activate and it doesnt working yet, the (venv) isnt appearing
please someone could help me? I tried everything I could find lol
It looks like you are using Git Bash or a similar bash-like system for Windows. You need to run Scripts/activate.sh in this environment.
For PowerShell, use Scripts/activate.ps1, and for cmd use Scripts/activate.bat.
What terminal are you using? Please create a new powershell or cmd terminal. Also you should not open the folder of the virtual environment as a workspace. Below are the correct steps.
Create a new folder as a workspace, then open this folder in vscode
Create a new terminal using the following command to create a virtual environment
python -m venv .venv
Use the following command to activate the environment after creation
.venv\scripts\activate
Another way is to select the interpreter of the virtual environment in the Select Interpreter panel after creating the environment
And then the new terminal will automatically activate the environment
You can read creating-environments and venv.
VS Code v1.58.1
Python v3.92
In a python project, I set up a virtual environment. In this project folder, I have a sub-folder .vscode that contains a file settings.json, which has the following contents (pointer to the project's virtual environment folder):
{
"python.defaultInterpreterPath": "D:\\Documents\\coding\\pyproj1\\proj_env\\Scripts\\python.exe",
"python.terminal.activateEnvironment": true
}
When I open this project folder in VS Code, the powershell terminal does not automatically launch the virtual environment, and in the lower left corner of VS Code, the virtual environment python interpreter is not listed. When I run a new terminal in VS Code, the virtual env is still not activated.
I had the same problem when I was using python.pythonPath which I understand is now deprecated in favor of python.defaultInterpreterPath.
If I leave VS Code alone for a few minutes after opening the project folder, it will sometimes select the virtual env interpreter. But since I'm telling VS Code where it is, why isn't it selecting this at folder open?
Where am I going wrong?
The python.defaultInterpreterPath setting only works at the first time.
After you manually select the python interpreter, the VSCode will remember it. When you reopen the VSCode, it will select the interpreter the last time you have selected. And the python.defaultInterpreterPath setting will have no influence anymore.
But you take this command to reset it: Python:Clear Workspace Interpreter Setting.
Update:
You can set the python.defaultInterpreterPath like this:
"python.defaultInterpreterPath": ".venv\\Scripts\\python.exe"
It looks like has some problem with your Python extension or the cache.
Could you try to:
Reinstall the python extension. Remember to delete the extension folder under: C:\Users\${UserName}\.vscode\extensions
Delete all the files under these locations:
C:\Users\${UserName}\AppData\Roaming\Code\User\globalStorage
C:\Users\${UserName}\AppData\Roaming\Code\User\workspaceStorage
Or you can empty the folder of:
C:\Users\${UserName}\AppData\Roaming\Code
But remember to storage the settings.json under
C:\Users\${UserName}\AppData\Roaming\Code\User
As described in the earlier comment: "So it seems my issue is that VS Code does not remember the interpreter I used last time."
What resolved the issue is deleting the virtual env and recreating it. Now when I open the project folder, VS Code auto activates the virtual env.
Steps involved for anyone wishing to do the same:
activate virtual env
create requirements file: pip freeze > requirements.txt
deactivate to exit venv
rm proj_env or whatever the name of the venv folder is
create virtual env, e.g., python -m venv proj_env
activate the virtual env (VS Code may detect the venv during creation, and ask if you wish to activate venv, go ahead and say Yes)
pip install -r requirements.txt to install the requirements into the virtual env
No matter what folder am I'm, command 'pipenv shell' creat virtualenvironment named by my username, doesn't create virtualenvironment named by my project(folder's name). Could you please help me with that?
According to your description, I used "pipenv shell" to create a virtual environment on my computer. When it was originally in the global environment python3.8.3, it was named ".venv" by default:
It is recommended that you exit the original virtual environment before using "pipenv shell" to create a virtual environment. In addition, as 'cizario' said, we often use the command "python -m venv .venv_name" in VSCode to create a virtual environment and it can still be in this virtual environment automatically after refreshing the console:
Reference: Virtual environment in VSCode.
I have created a virtual enviroment using virtualenv command with a standard procedure. Now, when I activate it or deactivate, the output of which pip or which python gives me same output /usr/local/bin/pip. However there is copies of python and pip commands in my vitrual enviroment directory - I have found them there. What might be the problem?
Did you move the virtual environment folder to a different name? The original path to the virtual environment is written into the generated activate script so if you move the environment activate will set your path to the old path of the virtual environment.
To fix this run virtualenv --relocatable $YOUR_VIRTUALENV_PATH then modify the VIRTUAL_ENV variable in the activate script to point to your new location.
I think it happen when I moved the environment folder to a different location.
I solved it by reinstalling virtualenv and creating a new environment
I have cygwin installed on a windows 7 machine. I'm trying to follow the instructions listed here:
https://www.tutorialspoint.com/flask/flask_environment.htm
Created a new project directory
cd into the new directory
Typed virtualenv venv, and it created the new virtual dir successfully
This next step fails to work for me.
I'm trying to activate the virtual env but its not working.
"venv\scripts\activate"
When i type that nothing happens.
USER#PCTEST~/newproj
$ venv/Scripts/activate
USER#PCTEST ~/newproj
$ which python
/cygdrive/c/python27/python
Solution
Run activate script with source or . (dot space) command:
source ./venv/Scripts/activate
# Or
. ./venv/Scripts/activate
Explanation
source runs shell commands in your current shell environment, so venv works as expected. While running script by name starts new isolated shell environment, activates venv there and closes new shell environment returning to original one.
