I want to duplicate my Python development station. I need to be able to install, with pip, the same libraries that were installed on the original station. Is there a simple way to that instead of going into the pip list and installing all the libraries one by one ?

The Main purpose is to be able to duplicate the same environment that I have in one station to another station with minimum overhead. I won't like to be required to track the existence or absence of the libraries by myself

    You should use virtual environments. Commented Jan 3, 2018 at 15:01

    If under linux then $ pip freeze > requirements.txt and then $ pip install -r requirements.txt Commented Jan 3, 2018 at 15:05
  • this is now the officially recommended tool: github.com/pypa/pipenv Commented Jan 3, 2018 at 15:06
  • If you are using pycharm ==> change the interpreter and then select from conda package install which libs you want to install. Commented Jan 3, 2018 at 15:26

What if I don't have a virtual environment ? Will "pip freeze" function the same ?
@MosheS. if you don't have a virtual environment, all the python libraries on your pc will saved on requirements.txt
You mean all the Python libraries that were installed by pip. Right ?
All python libraries, not necessarily just those installed with pip
Just to help others, I found out that the freeze created the requirements only for the list of libraries that were installed with pip.
