VS Code integrated terminal not starting with virtual environment activated while the right interpreter is being selected - python

Platform and software versions:
Mac OS Mojave, VS Code 1.38.0, Python extension installed. Created
virtual environment in project directory using command
python3 -m env.
Modified setting in Python extension,
"python.venvPath": "bin", to handle the bin directory where the python for the virtual
environment is stored.
Situation:
When I launch VS Code using code ., and then open a python file in the folder, the interpreter selected is ./bin/python, however the integrated terminal is not set to the right python executable. If I launch a new terminal it sources the virtual environment (which may be due to the Python extension setting "python.terminal.activateEnvironment": true)
Question:
Is there a way to have the integrated terminal also have the virtual environment sourced?
Or is there a better way to have VS Code activate virtual environment created by python3 -m env .?
Thank you.
Edit:
Just reread the VS Code documentation here - https://code.visualstudio.com/docs/python/environments and this time noticed this below. Wondering if there is a way to kill the existing terminal and then launch one upon VS Code launch...
However, launching VS Code from a shell in which a certain Python environment is activated does not automatically activate that environment in the default integrated terminal. Use the Terminal: Create New Integrated Terminal command after VS Code is running.

Two things. One, "python.venvPath" is meant to point at a directory that contains other virtual environments, not the bin/ directory that has a Python interpreter from a virtual environment. (I also don't know what python3 -m env is supposed to do; did you mean python3 -m venv?)
Two, there isn't a way to make VS Code automatically launch and complete the loading of the Python extension before VS Code creates a terminal if you have the terminal frame open at start-up.

At the time of this writting vscode now has
"python.terminal.activateEnvInCurrentTerminal": true,
so I my global settings.json, F1 > preference: Open Settings (JSON)
"python.venvPath": "D:/miniconda3/envs",
"python.terminal.activateEnvInCurrentTerminal": true,
and in my workspace's settings.json, F1 > preference: Open Workspace Settings (JSON)
"python.defaultInterpreterPath": "D:/miniconda3/envs/my-workspace-venv/python.exe"
And it works for me.

VSCode does not recognize venv

When I create a new project and the virtual environment using the venv python package, VSCode doesn't recognize the new virtual environment. I follow the bellow instruction:
https://code.visualstudio.com/docs/python/environments
The command that I use in the VSCode integrated terminal is:
python -m venv .venv
The terminal that I use is PowerShell 7, But I tried the CMD terminal too.
After running this command, the .venv folder is created very well on the workspace and I checked its behavior on the terminal.
I tried conda package manager to create a venv and VSCode recognizes it. The problem is only with the venv Python package.
I also tried another Python version to create venv, But the problem still exists.
I read this question:
How can I set up a virtual environment for Python in Visual Studio Code?
I know how to add an environment manually, but I expect VSCode to recognize my environments automatically.
I added these lines to settings.json (Preferences):
"python.venvPath": "~/.venv",
"python.venvFolders": [
"~/.venv/Scripts"
]
I activated the venv manually using VSCode integrated terminal.
The problem still isn't solved.
This is a screenshot of my problem:
I know how to add an environment manually, but I want it to be automatic.
I tried VSCode on another PC, and it worked; It doesn't need anything to do except the presence of venv.
VSCode Version: 1.58.0
Python Extension Version: v2021.6.944021595
The "python.venvPath" should be set to the parent folder of the .venv folder.
Virtual environments located in the folder identified by the
python.venvPath setting (see General settings), which can contain
multiple virtual environments. The extension looks for virtual
environments in the first-level subfolders of venvPath.
But, you need not set that. The Python extension should find the venv environment, as it is just located under your workspace folder.
Virtual environments located directly under the workspace (project)
folder.
I tried it locally, it does not work too. It will only show the cached environment path, and the "python.venvPath" does not work either.
And there are some changes of the interpreter storage:
A VSCode internal storage is introduced which will now store the
interpreter settings in the workspace & workspace folder scope.
You can refer to here for more details.
So, it's recommended to select the environment path manually for now.
After writing this command in VS CodeTerminal
python -m venv env
You can simply use
.\env\Scripts\Activate
In the same directory path where you have created the virtual enviroment.
For some reason VSCode had uninstalled all my Python extensions including the main Python extension. After reinstalling them it was able to detect my virtualenvs again.
So I was having this same issue and I resolved it by,
1. Open Settings in VSCode.
2. Search for "python.terminal.activateEnvironment"
3. If unchecked/unticked, then check/tick for both "User" and "Workspace".
The problem is not with VSCode but the workspace settings in which I was working on.
Just changed that and Voila works like a charm.

How to autoload venv/bin/activate in vscode on mac

I have django project folder with venv environment.
when opening vscode it has terminal opened in vscode.
Is there a way that I don't have to venv/bin/activate all the time when opening the project folder?
Edit (credit to #XJOJIX) from the comment in this answer. This will active the virtual environment without having to close or open terminals. A Python file still needs to be selected to load the Python extension.
Add this parameter in VS Code to "launch.json" or ".code-workspace"
"settings": {
"python.terminal.activateEnvInCurrentTerminal": true
}
Previous Answer:
To have a VS Code terminal automatically activate a virtual environment when first launching VS Code:
Close the terminal before exiting VS Code.
Open VS Code. Ensure a Python file is selected to direct VS Code to load the Python extension.
Wait for the Python extension to finishing loading (very bottom
left of VS Code terminal).
Open a new terminal after Python extension has loaded. The venv will automatically activate.
The trick is to open the terminal only after the Python extension has loaded.
If the directory of the terminal contains a virtual environment, VS Code will also automatically activate a virtual environment if a new terminal is opened. As before, a Python file must be selected and the Python extension must be fully loaded.
If you are on a mac OS, the simplest thing is to make ENV for your python projects.
Follow these simple Command in your Vs Code Terminal and you get your ENV activated :
Python3 -m venv env
source env/bin/activate
(The env in the first line is your env name so you can type any name)
Use the command palette to trigger the "Python: select interpreter" command. It should allow you to pick your virtual environment.
The article Using Python environments in VS Code migth be of interest to you.
If you use window machine, it might locate at
env/Scripts/activate
You can run above in your vscode terminal to activate your venv

How to set a Python Interpreter from inside a existing virtual environment in Visual Studio code

I want to open an existing virtual environment in Visual Studio Code. When I try to change the interpreter address inside of the settings.json (as instructed by https://code.visualstudio.com/docs/python/environments#_global-virtual-and-conda-environments) it doesn't work. With the virtual environment that I have, there is no python.exe file, I believe that is the issue as to why the following settings.json file doesn't work.
{
"python.pythonPath": "D:\\GitProjects\\OrganizationApp\\venv1\\bin\\python"
}
First of all Try open the root folder which venv folder resides in with Visual Studio Code.
(If you are on Linux you can just got the directory and open terminal and type code).
You should get a pop up to change the interpreter.
If not then Open your command palette Ctrl + Shift + P
Search for Python interpreter and select the Venv one.
According to your description, you could refer to the following steps to check the creation and use of the virtual environment in VSCode:
Prerequisites.
Check if python is available.
Enter cmd from the computer, enter the cmd window, enter python, and output the python version number to represent python is available.
If it is not available, please check the python installation package and check the python environment variables.
The python extension was successfully installed in VSCode.
Create and use a virtual environment:
Create a virtual environment in the vscode terminal. python3 -m venv ./venv1 or python -m venv ./venv1 Reference: virtual environments.
Select Yes when the prompt box pops up.
Then the interpreter will automatically be replaced with the created virtual environment.
After restarting VSCode, there is no python interpreter displayed in the lower left corner. We can create or open a python file and it will automatically display the interpreter.
Click on the interpreter to choose other available interpreters.
Use the shortcut key Ctrl+Shift+` to open a new terminal and enter the virtual environment.
Update:
When I open other projects or don’t open any project in VSCode , the virtual environment created before is not displayed in the python interpreter options. The reason is that the virtual environment we created is based on the current project and it exists in this project. like this:
Although this virtual environment is not displayed in other projects, I can use this virtual environment by selecting the python.exe of the virtual environment ( 'enter interpreter path' '.venv' 'Scripts'). Therefore, if there is no python.exe, it is recommended to create a new virtual environment.

Can't run Venv in VsCode

For the last 3 days, I have been trying to set up virtual Env on Vs Code for python with some luck but I have a few questions that I cant seem to find the answer to.
Does Vs Code have to run in WSL for me to use venv?
When I install venv on my device it doesn't seem to install a Scripts folder inside the vevn folder. Is this out dated information or am I installing it incorrectly. I am installing onto Documents folder inside my D: drive using python3 - m venv venv. The folder does install and does run in WSL mode but I am trying to run it in clear VsCode so I can use other add-ons such as AREPL that doesn't seem to like being ran in WSL.
For extra context I have oh-my-ZSH set up and using the ubuntu command line on my windows device. Any information will be helpful at this point because I am losing my mind.
venv folder in side D: drive
result
If you have the python extension installed you should be able to select your python interpreter at the bottom.
You should then be able to select the appropriate path
Run Set-ExecutionPolicy Unrestricted -scope process before activating virtual environment.
All the best
You don't have to create a virtual environment under WSL, it will work anywhere. But the reason you don't have a Scripts/ directory is because (I bet) you're running VS Code with git bash and that makes Python think you're running under Unix. In that case it creates a bin/ directory. That will also confuse VS Code because the extension thinks you're running under Windows.
I would either create a virtual environment using a Windows terminal like PowerShell or Command Prompt or use WSL2.

Auto activate virtual environment in Visual Studio Code

I want VS Code to turn venv on run, but I can't find how to do that.
I already tried to add to settings.json this line:
"terminal.integrated.shellArgs.windows": ["source${workspaceFolder}\env\Scripts\activate"]
But, it throws me an 127 error code. I found what 127 code means. It means, Not found. But how it can be not found, if I see my venv folder in my eyes right now?
I think it's terminal fault. I'm using Win 10 with Git Bash terminal, that comes when you install Git to your machine.
This is how I did it in 2021:
Enter Ctrl+Shift+P in your vs code.
Locate your Virtual Environment:
Python: select interpreter > Enter interpreter path > Find
Once you locate your virtual env select your python version:
your-virtual-env > bin > python3.
Now in your project you will see .vscode directory created open settings.json inside of it and add:
"python.terminal.activateEnvironment": true
don't forget to add comma before to separate it with already present key value pair.
Now restart the terminal.
You should see your virtual environment activated automatically.
Actually the earlier suggested solutions didn't work for me, instead I added the following in my settings:
"settings": {
"python.terminal.activateEnvInCurrentTerminal": true,
"python.defaultInterpreterPath": "~/venv/bin/python"
}
Of course replace the defaultInterpreterPath (used to be pythonPath) setting with your own path (so don't copy/paste the second line).
You don't need this line at all. Just remove it and switch your Python interpreter to point to the one within your venv. Here's a relevant documentation (italicized emphasis mine):
To select a specific environment, use the Python: Select Interpreter
command from the Command Palette (Ctrl+Shift+P).
... and
opening a terminal with the Terminal: Create New Integrated Terminal
command. In the latter case, VS Code automatically activated the
selected environment.
Once you switch the interpreter VS code should create a .vscode folder within your workspace with a settings.json indicating the python interpreter. This will give VS code the direction of where to locate the venv.
There is a new flag that one can use: "python.terminal.activateEnvironment": true
my scenario was pretty much the same. I am running VSCode on Windows, wanting to used git bash as my default Terminal but after the venv got created, it was doing some weird stuff when a Terminal would open where it couldn't find the correct python interpeter in the venv/Scripts folder even though I did ctrl-shift-p a bunch of times to reset it to the python.exe there. I also wanted to make sure the activate script was run on Terminal open. I just couldn't get the debugger to work right and it kept complaining that it could not find the python interpreter, so I basically couldn't debug at all.
So for anyone who is having weird stuff happen trying to use a Git Bash Terminal in VSCode in Windows related to a python project using a virtual env, here is what I found out;
I noticed that when I opened a new Git Bash Terminal, and looked at the $PATH variable to make sure it could find the interpreter in the venv, the path to the venv/Scripts folder would be prepended to the $PATH, but not with linux path separators like everything else in $PATH but with a Windows style path;
echo $PATH
C:\Users\blah\Documents\blah\Stock-down\Dev\this_api\venv/Scripts:/c/Users/blah/bin:/mingw64/bin:/usr/local/bin:/usr/bin:/bin:/mingw64/bin:/usr/bin:/c/Users/blah/bin:/c/Program Files/Go/bin:/c/Python39/Scripts:
So whenever I would try to debug, or just even run which python, It would get confused and thought the interpreter was in here;
which python
C:\Users\blah\Documents\blah\Stock-down\Dev\this_api\venv/Scripts/C/Users/blah/Documents/blah/Stock-down/Dev/this_api/venv/Scripts/python.exe
I ran the "printenv" command in the Terminal to see what env vars were getting set and why the venv interpreter path was getting messed up. And I found a env var I didn't know existed - VIRTUAL_ENV. But I didn't know how it was getting set or where it came from. After some pain, and hunting around I found it - when you run "python -m venv venvname" to create the virtual env in the project folder, as you know, it creates the activate (and activate.bat for windows) scripts in the ./venv/Scripts folder. Inside these files this VIRTUAL_ENV variable is not only exported, but but prepended to the $PATH variable on Terminal open with the "/Scripts" folder name added in linux path style. The problem with is that it sets the VIRTUAL_ENV value with windows type path - I know its painful and wrong to do this, but I just changed it to what Git Bash is expecting, see below;
#unset irrelevant variables
deactivate nondestructive
#VIRTUAL_ENV="C:\Users\blah\Documents\blah\Stock-down\Dev\this_api\venv"
VIRTUAL_ENV="/c/Users/blah/Documents/blah/Stock-down/Dev/st_api/venv"
export VIRTUAL_ENV
_OLD_VIRTUAL_PATH="$PATH"
PATH="$VIRTUAL_ENV/Scripts:$PATH"
export PATH
Now when a new Git Bash Terminal is opened it prepends the venv/Scripts path correctly to $PATH;
echo $PATH
/c/Users/blah/Documents/blah/Stock-down/Dev/st_api/venv/Scripts:/c/Users/blah/bin:/mingw64/bin:/usr/local/bin:/usr/bin:/bin:/mingw64/bin:/usr/bin:/c/Users/blah/bin:/c/Program Files/Go/bin:/c/Python39/Scripts:
I also made a copy of the executable python.exe in the ./venv/Scripts dir and just called it "python" and now the command "which python" works and I can debug fine. I still set ctrl-shift-P when I choose the interpreter in VSCODE to "python.exe" when I just use "find" during the selection.
For more information on VIRTUAL_ENV var, see this doc -- python venv docs
It feels like jumping through a bunch of hoops I know, but this way I can open a new Git Bash Terminal, have the activate script run correctly on Terminal Open, debug, and operate normally without having to float between Git Bash AND WSL Ubuntu AND Powershell, etc.
My environment started to activate automatically after the advice from this article
When you create a new virtual environment, a prompt will be displayed
to allow you to select it for the workspace. This will add the path to
the Python interpreter from the new virtual environment to your
workspace settings. That environment will then be used when installing
packages and running code through the Python extension. For examples
of using virtual environment in projects, see the Python, Django, and
Flash tutorials.
My solution was to create /.vscode/settings.json manually
Here is the tree;
├───django
│ ├───.vscode
│ │ ├───settings.json
I created /.vscode/settings.json then added this code in settings.json (I am using windows so I used double backslash for path location otherwise it gives unicode error, and don't copy paste this, find your own .virtualenvs)
{
"python.defaultInterpreterPath": "C:\\Users\\Talha\\.virtualenvs\\django-okd21pq9\\Scripts\\python.exe"
}
