내가이를 참조하십시오다음은 오류 스택입니다! 고맙습니다.

Answer 1

새 레일즈 프로젝트의 database.yml 파일로 이동하십시오 (Lynda.com의 경우 simple_cms 프로젝트를 의미 함).

왼쪽에있는 키를 같이 한 후 공백, 콜론되어 있는지 확인합니다 :

password: secret_phrase 

그리고하지이 좋아, 콜론 다음 공백없이 :

password:secret_phrase 

Answer 2

아주 좋은 @ 스틸,하지만 공간을 해결하지 해결할 수 있습니다 (오류의 수를 증가). 하지만 실제로이 오류는 문제가 database.yml에 있음을 나타냅니다.

제 경우에는 두 개의 명령문 소켓이 있습니다.

코드의 들여 쓰기가 중요합니다.

development: 
    adapter: mysql2 
    encoding: utf8 
    reconnect: false 
    database: xxx 
    pool: 5 
    username: xxx 
    password: xxx 
    socket: /socket_adress 
test: 
    adapter: mysql2 
    encoding: utf8 
    reconnect: false 
    database: xxx 
    pool: 5 
    username: xxx 
    password: xxx 
    socket: /socket_adress 
production: 
    adapter: mysql2 
    encoding: utf8 
    reconnect: false 
    database: xxx 
    pool: 5 
    username: xxx 
    password: xxx 
    socket: /socket_adress 

Answer 3

나는 또한 동일한 문제가 있었으며 들여 쓰기와 간격이 database.yml에서 정확했지만 오류가 계속 발생했습니다. 내 경우에는 들여 쓰기가 application.yml의 해당 줄에서 올바르지 않습니다.
