I am trying to compile Python 3 on Centos7 and I am getting "ModuleNotFoundError: No module named '_ctypes'"
Context: Centos7 uses Python 2.7.5 for its routines, so it is need to leave original Python 2.7.5 untouched. Python 3 (in case 3.7.3) needs to be compiled for alternate install. I am downloading source from python.org and using verbatin instructions from https://danieleriksson.net/2017/02/08/how-to-install-latest-python-on-centos/. I just changed version to 3.7.3. The compilation of 3.7.3, 3.7.2, 3.7.1 fails with following msgs: # make && make altinstall . .
