Didactic library

This should install numpy==1.14.0 but it doesn't:

classDiagram

pkgA --|> pkgB
pkgA --|> numpy
pkgA : numpy>=1.14.0
pkgA : pkgB

pkgB : numpy==1.14.0
numpy : whatever

conda create -n tst2 python=3.6 pip=18 -y
conda activate tst2

git clone https://github.com/KikeM/pkgA.git
git clone https://github.com/mmngreco/pkgB.git

cat pkgA/setup.py
cat pkgB/setup.py

pip install pkgA/. --process-dependency-links -I --no-cache-dir
pip freeze | grep numpy  # numpy==1.17.1 ??

This should crash installation process but it doesn't with incompatible versions of numpy.

classDiagram

pkgA --|> pkgB
pkgA --|> numpy
pkgA : numpy>=1.14.0
pkgA : pkgB

pkgB : numpy==1.13.0
numpy : whatever

cd pkgA
git checkout crash  # pkgA

cd ../pkgB
git checkout crash  # pkgB
cd ..

cat pkgA/setup.py
cat pkgB/setup.py

pip install pkgA/. --process-dependency-links -I --no-cache-dir
pip freeze | grep numpy  # numpy==1.17.1
