Receber mensagem de erro de sintaxe ao tentar iniciar o servidor de aplicação para a primeira aplicação Rails, após a configuração [noob]

Question

A seguinte mensagem aparece quando eu entro $ rails server no Terminal (Mac, executando a versão mais recente do Yosemite).Eu estou muito perdida, outros tópicos têm recomendado alterar o texto na pasta config do meu projeto, mas o que tentei não funcionou e eu estou supondo, pois, aqueles que são um pouco datado de tópicos.

Eu estou aprendendo com a Aprender Ruby on Rails livro tentando chegar a este MailChimp aplicativo de trabalho, concluído até o dia 13 capítulo, sem grandes problemas.Qualquer ajuda é apreciada.

Answer 1

Talvez o seu variáveis ENV não está configurado corretamente, ou você tem um personagem incomum em uma das variáveis.Ser cuidadoso não existem caracteres de tabulação ou quaisquer caracteres incomuns no config/segredos.yml arquivo.

Eu sugiro que você substitua todos os ENV valores no config/segredos.yml com codificado cadeias de caracteres.Não verifique o arquivo em git com o seu credenciais no arquivo.Apenas um teste para ver se você pode isolar o problema.
