Let's say that Python has virtual environments env1, env2.
When working with files within env1, I select the env1 interpreter, and when working with env2, I repeat the task of switching to the env2 interpreter.
Can't I skip this course? Because this is too cumbersome.
When I open a file in virtual environment env1, I want the env1 interpreter to be automatically selected, and when I open a file in virtual environment env2, I hope the interpreter change itself without selecting a separate setting menu.
I'm using Pycharm. If possible, I want to know the function in Pycharm, and if it's not right, it's okay to do it in VS code.
I want to be able to set up environment variables in my virtual environment so that they are available in my code when I activate the virtual environment. I make my virtual enviornments with venv. I'm working on a Windows machine with VS-code.
What I already tried, but didn't work.
Adding the vars to end of the activate.bat file like this:
set CLIENT_SECRET="MYSECRET"
Adding the vars to the end of the Activate.ps1 file like this:
$CLIENT_SECRET="MYSECRET"
Adding the vars to the end of the activate file like this:
export CLIENT_SECRET="MYSECRET"
I found a lot related to my topic, but none working for me. What to do?
If you want to setup your development environment in VSCode you can simply add .env file with all secrets defined in project root directory. More details in docs
Your first solution
set CLIENT_SECRET=MYSECRET
in activate.batshould work, when using Command Prompt in the terminal as Default Shell.
You can omit the quotes unless they are part of your envirionment variable.
You can verify, if the environment variable is set with:
echo %CLIENT_SECRET% in the terminal in VS-Code.
go to endowment variable folder enter Script folder now activate with cmd
use set in CMD teminal
use env: in powershell
I want VS Code to turn venv on run, but I can't find how to do that.
I already tried to add to settings.json this line:
"terminal.integrated.shellArgs.windows": ["source${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"
}
When using cmd.exe as the terminal application in PyCharm, the Python venv for the project gets automatically activated, so, I don't need to run venv\Scripts\activate. But when using PowerShell this doesn't happen. Is it possible to make this happen?
This is the option that has to be ticked to activate the Python virtual environment:
which is ticked by default and was ticket in my case. The reason why it wasn't working (and failing silently) was because I move the parent directory to a different location on my hard drive and that seemed to break the venv. Deleting it and re-creating it fixed the problem.
I have Anaconda and I've been playing around with setting up virtual environments since I have scripts that I need to run that have been written in Python 2 and Python 3. I want to be able to activate my Python 3 virtual environment in a specific directory - ie Python 3 will only run in that directory and all other directories will remain at the default Python 2 that I have set in Anaconda. My problem is that every time I try to activate a new environment, it changes the version of python used everywhere on my machine instead of just in the one directory that I want. Is it possible to create a virtual environment that is limited to a specific location?
I've tried the following:
conda create --prefix=testEV1 python=3.5
source activate testEV1
and this changes my version of python everywhere in my workspace to 3.5.
No. You only have a single default Python installation in effect at any one time.
Once you're done using one virtualenv you can use deactivate to go "back" to the standard, physical default Python installation.
Or you can use different command sessions with different virtual environments activated in each session.
Or you can explicitly invoke one version or another of Python from the command line each time, rather than just using the currently active-by-default one.
It is possible to autoactivate a conda environment when entering a specific directory.
https://github.com/conda/conda/issues/5179
BUT, it doesn't change the fact that source activate xxx affect your shell/prompt instead of your directory structure. You can still manually activate an environment and it will still affect your whole prompt.
