Question

您好我目前正在迈克尔哈特尔教程的第6章。在我设法将它送到heroku之后，bundle exec rake db:migrate无法正常工作并且它一直给我以下错误。我已经尝试将几个用户名和密码添加到database.yml文件中，但无济于事。任何人都可以对此有所了解吗？

** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
** Invoke db:load_config (first_time)
** Execute db:load_config
** Execute db:migrate
rake aborted!
PG::Error: FATAL:  password authentication failed for user "amuudiqbgwhemy"

Tasks: TOP => db:migrate

Answer 1

在您将应用推送到heroku之后，您应该尝试运行（从您的本地终端）

heroku run rake db：migrate

在上下文中，您不必在database.yml文件中设置用户名/密码，因为您正在使用的Postgres数据库是通过使用postgres附加组件设置的配置变量来设置的。

bundle exec rake db：migrate
