i have brand new centos 7 vm trying install python 3 (currently 3.6.0) on. following guide daniel eriksson (https://danieleriksson.net/2017/02/08/how-to-install-latest-python-on-centos/)

but i'm running pemission denied error when running make && make altinstall command.

i don't work linux, i'm not sure or try next. on appreciated. thank you

the issue permission required when running command install package.

use
sudo make && sudo make altinstall

instead of:
sudo make && make altinstall
