I created an virtual environment and activate it but now I want to go back to my global environment, how I can do this using a comand?
.\geek\Scripts\deactivate.bat I run this command to deactivate my environment but I still in that Virtual Environment.

I have an issue where the windows defender firewall will only allow connections to python via a specific folder (e.g. C:Anaconda/python.exe) (This is a conda environment)
I would like to run an API in a virtual environment, however that environment uses another folder. (e.g. C:VEnv)
Rather than update the packages in the conda environment, I would much prefer the control of a virtual environment for the API, but it cannot be reached outside of the PC running it due to the PC windows firewall restrictions. Is there some sort of setting that would allow me to use the python.exe from another folder from within the venv?
Am I in denial that there is any solution to this problem other than opening up the defender firewall?
I have tried running the API in the virtual environment (maybe im missing a setting?) No luck.
I have tried running the API in the conda environment, and a whole load of other stuff broke, which will take a long time to fix.
I do have the API running from the virtual environment being accessed within its own PC, but externally there is nothing.
I created my first virtual environment for a django app that I created following a tutorial guide. Now I'm not sure, can I use this very same environment (same name), or do I need to create a new virtual environment when I create a new project?
I understand using virtual environments keeps your individual project dependencies and package versions isolated but my projects all have the same version of django and python. So far I'm not installing any other libraries and I'd imagine they would all just use the same version too. Is there something else I am missing here?
I just experimented with creating a new virtual environment from the current virtual env and I'm now in the newly created one once I activated it. Is it ok to create a new virtual environment from within another virtual environment? Is that any different from doing so outside a virtual environment?
If I were to use the same named virtual environment that I used for the old project, for this new project, what would the implications be?
As You stated in Your question venv (virtual environment) as in official python documentation allows You to create a snapshot of the dependencies that are used within a project so that You are not installing the dependencies in a "global" context which would mean Your main Python directory.
A virtual environment is a Python environment such that the Python
interpreter, libraries and scripts installed into it are isolated from
those installed in other virtual environments, and (by default) any
libraries installed in a “system” Python, i.e., one which is installed
as part of your operating system. A virtual environment is a directory
tree which contains Python executable files and other files which
indicate that it is a virtual environment.
So answering couple of the questions that were mentioned in Your post:
You don't need to create a virtual environment every time You start a new project.
You are not missing anything.
I am not quite sure about creating a virtual environment from within one. (check the directory structure of newly created virtual environment and confirm its contents)
The implications are that You have a shared virtual environment. Any changes to the environment itself are going to influence both projects.
I would highly recommend for You to create named venv for each project independently. In my mind that will limit the probability of errors happening if You make any changes to the environment such as package updates and so on.
I am setting up a new project. I have installed virtual environment. But Do I have to install django again in that directory??
Each project should have its own, separate virtual environment. Reusing the same virtual environment for multiple projects kind of defeats the whole point of virtual environments.
When you want to create a new project, you first create a new virtual environment for it.
A newly created virtual environment is empty, so you have to install Django into it before you can run django-admin startproject.
Everytime you want to run an existing project, e.g. with python manage.py runserver, you first have to activate the virtual environment.
No, you need not to install django again. You can invoke the virtual environment again.
If you have installed virtual environment in the project folder and have configured it that way, then you perhaps have to create a new virtual environment.
There are good tools available:
pyenv
virtualenvwrapper
A good reference point can be RealPython for managing different versions of django.
Yes, you should install Django with every project you start with.
I have been working with Atom text editor, Anacond and Python for a project and I am able to activate the virtual environment, however, when I type in the command to activate the virtual environment, it does nothing. I have attached a screenshot.
However, when I run the command, conda info --envs I am able to view the environment.
Please advise.
Thanks in advance for help.
What is the proper way of adding an already existing Django project to a newly created virtual environment? Do I just move the project to the virtual environment root directory?
It doesn't matter where the directory is - the only important thing is that you activate the virtual environment every time you want to work on the project.
I personally prefer to have the project directory inside the virtual env directory, but that is not required.
One caveat: don't put the virtual env inside your project directory. That may cause problems with test discovery and with git.
