Erro ao executar (npm start)

Olá, Marcos! Tudo bem? =)

Você lembrou de fazer o comando npm install? Ele é o responsável por baixar as dependências... Depois dele você pode rodar o npm start. =)

Fábio

Ele não conseguiu encontrar o express. Confirma se dentro da tua pasta alurapic tem uma pasta node_modules e se dentro dela tem uma chamda express.Caso você não tenha nenhuma dessas pastas vá de novo na pasta do alurapic e executa o npm install porque algo de errado aconteceu na hora de executar esse comando.Se você tiver elas tenta apagar a pasta node_modules e executar o npm install para tentar baixar tudo de novo corretamente.OBS: Se você estiver com um pouco de preguiça, pode abreviar e usar o comando npm i que é um atalho para o install.

Marcos, você não pode executar o npm start antes de executar o npm install. É por isso que ele esta dizendo que não encontra o módulo express, porque ele não foi baixado pelo comando npm install.

Faça o procedimento novamente e poste o resultado.

Eu tinha executado o comando instal, como podem ver abaixo. mas quando rodei novamente o comando ele funcionou.

Muito Obrigado pela ajuda pessoal!

Você escreveu install errado no exemplo dado. Quando rodou novamente deve ter escrito certo. Acontece.
