Something I realise is your composer json file will have some sort of script like    scripts          post-root-package-install              php -r   copy   env example     env                   post-create-project-cmd              php artisan key generate              post-install-cmd              php artisan clear-compiled            php artisan optimize              pre-update-cmd              php artisan clear-compiled              post-update-cmd              php artisan optimize              post-autoload-dump              Illuminate  Foundation  ComposerScripts  postAutoloadDump             php artisan package discover             what works for me     scripts          post-root-package-install               php -r   file exists   env      copy   env example     env                   post-create-project-cmd               php artisan key generate              post-autoload-dump              Illuminate  Foundation  ComposerScripts  postAutoloadDump             php artisan package discover             removing post install cmd helped running composer install without any issue   Hope this helps  Cheers

We got an error because we have missing vendor folder in our project  The vendor directory contains our Composer dependencies   Need  vendor folder because all packages are there and including all the classes Laravel uses  A problem can be solved after following just two steps   composer update --no-scripts  composer update    --no-scripts  Skips execution of scripts defined in composer json composer update  This will check for newer versions of the libraries you required in your project  If a newer version is found and it s compatible with the version constraint defined in the composer json file  it will replace the previous version installed  The composer lock file will be updated to reflect these changes    These two commands  we will Recreate the vendor folder in our project and after that our project will be working smoothly
