使用脚本安装python软件包

Question

I have a python script that use additional libraries. I want to write a additional script for downloading these needed packages. That script will run by the user before run the actual script. I am using Linux environment and all packages downloaded with pip or sudo from command line. What is the proper way to do serve that kind of script? Is setup.py created for that purpose?

Answer 1

There is a Pypi way to do that, use requirements.txt file.

# requirements.txt
numpy==1.5.1
scipy==0.9.0

Then run:

pip install -r requirements.txt

You can use pip freeze to get the currently installed packages.

pip freeze | grep numpy
# numpy==1.5.1
