Novo projeto Laravel não inicia

você rodou o comando composer install dentro do projeto ?

Oi Alan, não, só mexi com composer pra i stalar o laravel em si.

Qual seria esse comando que tenho de executar dentro da pasta do projeto?

Dentro da pasta do projeto pelo terminal você vai usar o comando composer install

Olá José, tudo bom?

Consegui resolver o erro, é preciso executar o comando composer install dentro da pasta do projeto, mas vai aparecer vários erros na instalação do composer, porque é necessário algumas extensões do PHP executei os seguintes comandos:

$sudo apt-get update
$ sudo apt-get install php-mbstring
$ sudo apt-get install libnet-libidn-perl 
$ sudo apt-get install php-all-dev 
$ sudo apt-get install php-cgi 
$ sudo apt-get install php-cli 
$ sudo apt-get install php-common 
$ sudo apt-get install php-curl 
$ sudo apt-get install php-dev 
$ sudo apt-get install php-gd 
$ sudo apt-get install php-gmp

Apos você executar os comandos acima execute o comando composer install dentro da pasta do projeto, agora se você tentar rodar o comando php artisan serve vai funcionar normalmente.

Se seu erro foi solucionado, não esquece de marcar a resposta como solucionada, assim você ajuda outras pessoas que tiverem a mesma dúvida.

Abraço!

Olá, segui os passos que você descreveu, mas continuo com o mesmo erro, dizendo que o autoload.php não exite...

Qual é a versão do seu PHP?

rodei php -i no meu terminal e o resultado foi:

PHP Version => 7.1.0RC2

Execute os seguintes comandos no terminal:

$ cd
$ composer create-project laravel/laravel estoque "5.0"
$ cd estoque
$ php artisan serve

Funcionou, caso aconteça algum erro, mostre a mensagem de erro

Alguma sugestão?

Ainda faltava instalar uma extensão no php. Resolvi instalando:

sudo apt-get install mcrypt php-mcrypt
