Cannot Composer Install with Symfony - PhpStorm

Question

I had a problem with my Ubuntu so I needed to install back everything. Nearly all is done but when I start a new project with Symfony on PhpStorm, and when I do a composer install or composer update in the terminal I have an error that I don't know how to treat.

Script Sensio\Bundle\DistributionBundle\Composer\ScriptHandler::clearCache handling the symfony-scripts event terminated with an exception



[RuntimeException]                                              
  An error occurred when executing the "'cache:clear --no-warmup'" command:

  Config/Util/XmlUtils.php on line 52

I tried installing composer following this link but I don't recall using such practice.

So I cannot move forward with my project because I can't get past composer... if anyone knows why and could give me a step-by-step approach that would be truly appreciated.

Thank you

PHP's DOMDocument library is not installed. You need to install it. Try -

sudo apt-get install php-dom

Thanks for the answer. But when I do the command it says "Impossible to find php7-dom package"
