agora tento Este tutorial com um aplicativo de meteorito de baunilha:

meteor create meteor-thewhozoo

Mas quando tento ir ao servidor de Heroku ...

Eu li isso. adicionar a base de dados Mongo elimina o pedido de informações do cartão de crédito, mas não funcionou para mim.

heroku config:set MONGO_URL=mongodb://<dbname>:<password>@ds021026.mlab.com:21026/mongo-thewhozoo

Quero evitar dar detalhes do meu cartão para um ambiente de desenvolvimento/prova de conceito.

Os Detalhes Do Cartão podem ser evitados. Leia isto , (veja Configurar a compilação).
