"48: Address already in use" error

[Mauro Stettler]

you probably still have an nginx running and listening on localhost
port 80. what do you mean with install/uninstall, how did you do that?
after uninstalling did you make sure the running process is also dead?

try to "sudo killall nginx" and then try to run it again.
