I'm bit of a newb in macOS and I'm struggling to install composer on my macOS system. Whenever I try to execute
php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
in my terminal from here, I'm getting this error.
I tried to ask google, but there was no success for me.
If you can help me with this I would be very grateful. Also sorry for my english, I'm not a native speaker.
