Doing a pip install -r requirements.txt does not follow the order the modules are listed.
This answer points out how to do it.
I want to know how the order is determined by pip, and if the order is predictable in any way?

It follows package dependency. If package a in line 1 requires package x, then it will add package x which in turn may require package d. – alvits Jan 30 '19 at 20:00

@alvits Ah, I see. Looks like it is creating a dependency tree first and then starting at the leaves. It also looks like it installs git packages first. Any other rules you are aware of? – Roman Jan 30 '19 at 21:26

So if PIP is mentioned in the requirements.txt file, it will get installed 1st? – variable Jun 01 '20 at 07:30
