The rest of the log is similar.It just cant find the Redis class.

Answer 1

Ok,finally I solved it.Just install it with brew:
*brew install --without-apache --with-fpm --with-mysql --with-redis --with-curl --with-intl --with-iconv php72
echo 'export PATH="/usr/local/opt/php#7.2/bin:$PATH"' >> ~/.bash_profile
echo 'export PATH="/usr/local/opt/php#7.2/sbin:$PATH"' >> ~/.bash_profile
source ~/.bash_profile
*
I dont know if these options are right but I did have my php installed properly with all the exts I need.
