Some settings on your machine make Composer unable to work properly.
Make sure that you fix the issues listed below and run this script again:

The allow_url_fopen setting is incorrect.
Add the following to the end of your `php.ini`:
    allow_url_fopen = On

The php.ini used by your command-line PHP is: /opt/cpanel/ea-php73/root/etc/php.ini
If you can not modify the ini file, you can also run `php -d option=value` to modify ini values on the fly. You can use -d multiple times.
