Answer 1

run in your project root folder cmd with composer update command

Answer 2

You need to go to your project room and install dependencies. It says that there is no vendor folder. Vendor folder is a part of composer. It holds dependency files inside.

Run composer install in the project root. It is a good idea to run composer update after that.

Answer 3

For faster results you can use

composer update --verbose --prefer-dist

Answer 4

on your root folder run cmd by replacing root directory with cmd or open new terminal, navigate to your project root folder and follow the steps below
1 run composer install 2 composer update 3 restart your app 4 then run php artisan serve

Answer 5

If composer install / composer update isn't working for you, try:

composer install --ignore-platform-reqs

OR

composer update --ignore-platform-reqs

After this you should be able to run "php artisan serve".

Answer 6

run

 composer install 

Answer 7

In my case, there were some issues in composer. I resolved it by running this command in cmd in project's root folder:

composer update

Answer 8

On my case it was because the vendor file was missing. type this to fix it:

composer install --ignore-platform-reqs

but, still if i make a new project i have to fix the vendor file again.
