If you came across this error while using the command line its because you must be using php 7 to execute whatever it is you are trying to execute. What happened is that the code is trying to use an operator thats only available in php7+ and is causing a syntax error.

If you already have php 7+ on your computer try pointing the command line to the higher version of php you want to use.

export PATH=/usr/local/[php-7-folder]/bin/:$PATH

Here is the exact location that worked based off of my setup for reference:

export PATH=/usr/local/php5-7.1.4-20170506-100436/bin/:$PATH

The operator thats actually caused the break is the "null coalesce operator" you can read more about it here:

I had the same error and the problem is that I had not correctly installed Composer   I am using Windows and I installed Composer-Setup exe from getcomposer org and when you have more than one version of PHP installed you must select the version that you are running at this point of the installation

If you have newly upgraded your php version you might be forget to restart your webserver service

If I had to guess  I d say you installed the PPA 7 1 8 as CLI only  php7-cli   You re getting your version info from that  but your libapache2-mod-php package is still 14 04 main which is 5 6  Check your phpinfo in your browser to confirm the version  You might also consider migrating to Ubuntu 16 04 to get PHP 7 0 in main
