以前有人遇到过这个错误吗？或知道如何解决它？
更新 database.yml的：
default: &default
adapter: mysql2
encoding: utf8
collation: utf8_general_ci
pool: 5
username: myusername
password: mypassword
socket: /var/run/mysqld/mysqld.sock
development:
<<: *default
database: myapp_development
test:
<<: *default
database: myapp_test
production:
<<: *default
database: myapp_production
username: myapp
password: <%= ENV['MYAPP_DATABASE_PASSWORD'] %>
Gemfile：

答案 0 :(得分：0)
我通过从链接文件设置和.gitignore中删除database.yml来修复主要错误，并在服务器上创建它。
