 Generating optimized autoload files
 > Illuminate\Foundation\ComposerScripts::postInstall
 > php artisan optimize  Script php artisan optimize handling the post-install-cmd event returned with error code 1  Failed to install

[Symfony\Component\Console\Exception\RuntimeException] The "-e" option does not exist.

Above error comes because of options shortcuts… here composer - version means composer -v… and which is not working in your case. That's the reason behind the last error stack.

Refer this link to see GitHub issue. the -e option does not exist

instead of running composer -version try to run 

composer --version

and see it shows composer version or not...if not then the composer is not installed properly.

Then run 

laravel --version

if you don't see version there. install composer and laravel again. Below link will be helpful for step by step installation.

laravel new doesn't work
