Description
- Pip version: 10.0.0
- Python version: 3.6.5
- Operating system: Linux/Fedora
Description:
The requires build dependency listings in pyproject.toml doesn't appear to support PEP 508 environment markers.
Several projects appear to have expected pip would support this: pandas, scipy, pywt,
What I've run:
The following reproducer shell script
set -e -x
rm -rf mytest
mkdir mytest
cd mytest
python3 -mvenv env
./env/bin/pip install --upgrade 'pip>=10'
echo "assert False" > setup.py
cat <<EOF > pyproject.toml
[build-system]
requires = [
"wheel",
"setuptools",
"numpy==1.12.1;python_version<'3'",
"numpy==1.14.1;python_version>='3'",
]
EOF
./env/bin/pip wheel .This prints
+ rm -rf mytest
+ mkdir mytest
+ cd mytest
+ python3 -mvenv env
+ ./env/bin/pip install --upgrade 'pip>=10'

I would have expected it picks the a single appropriate numpy version based on the requirements markers, instead of trying to install two different versions and failing. (The test script will ultimately fail when it tries to run the setup.py --- in my real use I of course have a working setup.py but the behavior is the same).
