installing multiple python packages by single python file

问题

How to make a python file, which installs the mentioned python packages, on running that python file in console instead of installing packages one by one as we do by using pip I am also confused with setup.py is it same and if it is how to do please help

回答1:

You can make one text file which has your name of package requirements. Like this is requirement.txt

requests==2.7.0
selenium==3.4.3
Flask==0.10.1
retrying==1.3.3

then you can run it like

pip install -r requirement.txt

Note: Place this txt file to at where the pip is.

And for how this differs from the setup.py you can refer this
