When i do php artisan or php artisan serve in my laravel project it shows some error and I don’t know how to solve it. I tried removing composer and again installing it also doing composer update but it does not seem to solve the problem. Operationg System: Ubuntu 20.04 LTS
My Error:
wiggly@Wiggly-Faun:~/Desktop/Web Designing/websites/Ticketing$ php artisan serve PHP Warning: require(/home/wiggly/Desktop/Web Designing/websites/Ticketing/vendor/autoload.php): failed to open stream: No such file or directory in /home/wiggly/Desktop/Web Designing/websites/Ticketing/artisan on line 18 PHP Fatal error: require(): Failed opening required '/home/wiggly/Desktop/Web Designing/websites/Ticketing/vendor/autoload.php' (include_path='.:/usr/share/php') in /home/wiggly/Desktop/Web Designing/websites/Ticketing/artisan on line 18
When I do composer install inside my project is shows:

Answer
Did you installed all the necessary vendor packages locally? Does your “vendor” directory exists?
Don’t forget to use:
composer install
in the project directory to install necessary vendor packages.
Also, make sure you have installed necessary PHP extensions, such as mbstring and xml, you may install them via:
sudo apt install php-xml php-mbstring
Hopefullly this helps solve your question.
