Atualizei o angular e agora recebo a mensagem abaixo quando tento subir o servidor. Alguém tem alguma idéia ?

C:\sergio\cursos\alurapic\server>npm start

> alurapic@1.0.0 start C:\sergio\cursos\alurapic\server
> node server.js

module.js:471
    throw err;
    ^

Sérgio, aparentemente alguns módulos do node não foram encontrados tipo o Express, poderia rodar um npm install novamente e me falar o resultado?

Você usa Windows? Está com problemas de permissão. Sugiro remover tudo e instalar o Node 8.0.
