[FIXED] Pipenv installed packages on environment (Pipenv file)

Issue

I recently started to do some tutorials with python, I learned how to use venv and virtualenv but found them a little too complicated, since my developer background is basically javascript when I found pipenv I started using it. So far so good. My question here is about the pipfile that pipenv generates when I run pipenv shell in a specific folder, I'm currently learning how to build an API with Flask, the virtual environment works just fine, and everything I install in there works fine as well but the pipfile doesn't seem to be updating with the packages I'm installing, but when I check the dependency tree with pipenv graph it shows all the dependencies I've been using, so is there something I'm missing with how pipenv works, or should it work this way?

Note: Whenever I want to create a new env i follow these steps:

• mkdir app
• cd app
• pipenv shell
• pip install somepackage
• touch main.py (add my code)
• python main.py

Solution

You have to install packages using the command pipenv install [package] in order for pipenv to create/update the Pipfile and Pipfile.lock files.

As you already installed the dependencies with pip, you can run pipenv run pip freeze > requirements.txt && pipenv install -r requirements.txt and it will create or update the aforementioned files for you. It is best, though, that you declare each package you want because this method also writes each package dependencies on these files.
