I am preparing to format my laptop but I have many python packages installed and accommodated in different virtual environments, the same thing happens with node.js and many modules that I have. Is there a way to make a backup for all my libraries and restore them once formatted? so I would not have to manually install them again.
In Python you can use pip freeze to create a file requirements.txt of all your virtualenvs ( link )
pip freeze > requirements.txt # en el venv de turno
On the new machine you can do:
pip install -r requirements.txt # en el nuevo venv de turno
In nodejs you can create a package.json and then do:
npm install # en el mismo lugar donde esté el package.json
Take a look here .
