Question

当我运行bundle exec rake db:create：

时，请继续这样做

could not connect to server: Connection refused
    Is the server running on host "localhost" (::1) and accepting
    TCP/IP connections on port 5432?
could not connect to server: Connection refused
    Is the server running on host "localhost" (127.0.0.1) and accepting
    TCP/IP connections on port 5432?

任何想法如何解决这个问题？

Answer 1

这可能是因为许可问题。导航到/etc/postgresql/<your version of pg>/main/并打开pg_hba.conf。

在那里搜索一句话 local all postgres peer并将其替换为local all all trust。然后在终端中运行sudo service postgresql restart。

Answer 2

试试这个：

它会起作用

您的database.yml应如下所示：

development:
  adapter: postgresql
  encoding: unicode
  database: <DATABASE_NAME>
  pool: 5
  username: <username>
  password: <password>
  host: localhost
  port: 5432

对于其他环境也是如此

bundle exec rake db：创建错误
