Hi team,
We are trying to build keystone v15.0.0 from source on intel on sles12-sp4. But when we try to run the pip install command with requirements.txt it fails with the error python.h not found. Error log for pip install is `/crypto -I/usr/local/include -I/usr/include -I/usr/include/python2.7 -c src/scrypt.c -o build/temp.linux-x86_64-2.7/src/scrypt.o -O2 src/scrypt.c:28:20: fatal error: Python.h: No such file or directory #include ^ compilation terminated. error: command 'gcc' failed with exit status 1`
Further we executed "sudo tox -egenconfig" command which failed with below error -
`ERROR: Could not find a version that satisfies the requirement requests===2.22.0 (from -c https://git.openstack.org/cgit/openstack/requirements/ plain/upper-constraints.txt`
Full error log is as below:

Please help in fixing this build issue on Intel. Are there any known pointers?
"fatal error: Python.h: No such file or directory" means you need the python2 or python3 development libraries installed, which you can do by installing either the python-dev, python3-dev, python-devel or python3-devel package on your distribution, depending on what version of python you are using and what distro you are using.
