Solution 1

First Install Composer: composer install.
Then run a command in CMD prompt: composer dump-autoload.

Solution 2

Try running composer dump-autoload , after that run a composer install

If that doesn't work, try the composer update --no-scripts

Solution 3

I'm new to Laravel, and I got the same confusion with the command:

laravel new blog

There was no vendor folder.

But after I tried:

composer create-project --prefer-dist laravel/laravel blog

I found the vendor folder came up.

Don't know why either.

SOLUTION: laravel new project-name was actually giving me an error that i overlooked. I had the wrong version of php. It requires phpv7.1.3 or higher. If you don't have it it doesn't work.

Ran into one other problem:
- i had a system environment variable that is pointing to an old version of php
- Also laravel requires openssl extension and mbstring to turned on. UNCOMMENTED from php.ini
FOR NEWCOMERS: if you have just downloaded php and unzipped the file. It contains a file called

install.txt

that you HAVE to read. It explains everything.

I ran laravel new blog from their getting started page. When I tried to run php artisan serve, I got the following error:

Warning: require(C:\Projects\laravel-projects\blog/vendor/autoload.php): failed to open stream: No such file or directory in C:\Projects\laravel-projects\blog\artisan on line 18

The artisan file is pointing to
```
require __DIR__.'/vendor/autoload.php';
```
this directory does not exist. Even if I point it to the correct directory, it still wouldn't work because I don't have read permissions for that folder (so it gets denied).

What's going on, and how can I fix this?

EDIT: changed the url from the mentioned above to:

C:\Users\sarkis\AppData\Roaming\Composer\vendor\autoload.php

This worked perfectly for some reason. And NOW. A NEW ERROR HAS APPEARED.

Fatal error: Uncaught Error: Class 'Illuminate\Foundation\Application' not found in C:\Projects\laravel-projects\blog\bootstrap\app.php:14 Stack trace:#0 C:\Projects\laravel-projects\blog\artisan(21): require_once() #1 {main} thrown in C:\Projects\laravel-projects\blog\bootstrap\app.php on line 14

found that i don't have the proper version of php required.

  @CharbelSarkis Change permissions for your installation directory... You need to have, read, write, modify and for running locally execute also... Then run composer install and all should be fine...

  that folder doesn't even exist. The problem is i have installed laravel globally. When you run laravel new project it doesn't make your vendor folder. I just tried installing laravel without global and it worked

i do have permissions for the files it's just that the vendor folder doesn't exist and even if it did the actual folder that this needs is located in appdata/...../vendor/autoload

This doesn't change anything the file still points to an empty directory. Had to change the url to the correct one and got a new error

@Charbel Well that command won't install composer as of course you didn't expect to be able to install composer via composer, did you? That will install all the "dependencies" for your project that are missing for some reason, using composer and the composer.json file in root path of your project. So just do this: In the root path of your project, run composer install. Remember you have to run this in the path that the composer.json file of your project is located which in this case, will always be the root dir of your laravel project. It will download and install all the dependencies. Y

@arm That wasn't the problem. Apparently laravel requires php 7.2 from that point in time. And i had a much older version.
