Is parsing the requirements.txt and install packages specified in requirements.txt same as pip install -r requirements.txt?

Question

I would like to parse the requirements.txt and pip install each package individually.

Is it the same as doing pip install -r requirements.txt? Would the behavior still be the same?

Answer 1

its not the same...

if pip -r requirements.txt has any failures the whole thing would quit

if you install each one individually, then presumably if one failed it would just move on

is at least one difference
