Creating a virtualenv with preinstalled packages as in requirements.txt
Question:
Creating a virtualenv will create a virtual python environment with preinstalled pip, setuptools and wheels.
Is there a way to specify what packages to pre-install in that virtualenv apart from those 3 default ones? Either with CLI arguments, a file, or environment variables of some sort.
I.e. is there something along the lines of virtualenv venv && venv/bin/pip install -r requirements.txt which can be run in one command?
Answers:
You can do it with a tool called pipenv now!

Just run
pipenv install requests
And it will create a virtualenv and install requests in it
Typically the steps you always takes are:
git clone <repo>cd <repo>pip install virtualenv (if you don’t already have virtualenv installed)virtualenv venv to create your new environment (called ‘venv’ here)source venv/bin/activate to enter the virtual environmentpip install -r requirements.txt to install the requirements in the current environment
Try this:
virtualenv –system-site-packages venv
