how to print time took for each package in requirement.txt to be installed

Is there any convenient way to print the time took for each package when running pip install -r requirements.txt?

I would like something like pip install -r requirement.txt --print-times and instead of just printing the names of the package and the versions I would like the output to look something like this:

Collecting shellescape==3.8.1
  Using cached shellescape-3.8.1-py2.py3-none-any.whl (3.1 kB)
  took 2.4 seconds
Collecting lxml==4.5.2
  Using cached lxml-4.5.2-cp38-cp38-manylinux1_x86_64.whl (5.4 MB)
    Collecting gevent==20.9.0
  Using cached gevent-20.9.0-cp38-cp38-manylinux2010_x86_64.whl (6.1 
  took 4.4 seconds

etc...

I did not find this data under --verbose.

Thanks!


EDIT:

I'm aware of options like writing a bash/python scripts but I'm looking for a simple flag or single-line command.

I have a suggestions for you, you can use a python programm:

  • Open you requirement.txt (f = open('requirement.txt', 'r'))
  • Read the file (doc = f.readlines())
  • In a for loop take each lines
  • Initialise a timer (t0 = time.time())
  • Run pip install with pip package in python
  • Display the time it tooks (time.time() - t0)
  • Use an alias to replace run this script insteed of pip install

create a bash script with this content

while IFS= read -r line; do
    start=`date +%s`
    pip install $line
    end=`date +%s`
    runtime=$((end-start))
    echo "took $runtime seconds"
done < requirements.txt
