Boa tarde, estou no capítulo 8 do livro MEAN stack. Até esse capítulo, tudo estava indo bem, depois começou a dar problemas, daí baixei o código do githhub de vocês fui executar o servidor e apareceu essa mensagem de erro que não sei como resolver. Obrigado. Segue a mensagem no print que eu dei no commander.
λ node server
{ [Error: Cannot find module ‘…/build/Release/bson’] code: ‘MODULE_NOT_FOUND’ }
js-bson: Failed to load c++ bson extension, using pure JS version
