Erro ao gerar BUNDLE

Professor, segue liga nesse erro:

Consta como se não tivesse encontrado o C:\wamp64\www\CursoAlura\webpack\client\webpack.config.js, mas fiz conforme o senhor fez no exercício e com isso, não consigo gerar o bundle.

//Prompt
C:\wamp64\www\CursoAlura\webpack\client>npm run build-dev

> client@1.0.0 build-dev C:\wamp64\www\CursoAlura\webpack\client
> webpack --config webpack.config.js
