有人知道这里发生了什么事吗？
答案1
我对 ruby on rails 的经验很少，但通过阅读输出，我怀疑这是一个密码问题。
第 8 行内容如下：
fe_sendauth: no password supplied
然后转向中间：
Couldn't create database for {"adapter"=>"postgresql", "encoding"=>"unicode", "database"=>"bathrooms_development", "pool"=>5, "host"=>"localhost", "username"=>"root", "password"=>nil}
fe_sendauth: no password supplied
似乎服务器需要密码才能建立连接，但您没有在连接字符串中提供密码。如果我没记错的话，建议在开发 RoR 应用程序时使用“开放”（即无密码）帐户。
我建议你创建一个数据库用户所有管理员（坏主意，抱歉） create权限但没有密码，并将该帐户用于开发目的。在 postgres 服务器的本地/测试实例上执行此操作以避免暴露任何数据。

您需要在文件中为 Postgres 服务器指定数据库适配器设置config/database.yml。使用类似以下内容：
development:
adapter: postgresql
host: 127.0.0.1
database: my_app_db
schema_search_path: my_app_schema, public
encoding: unicode
pool: 5
timeout: 5000
username: my_user
password: my_pass
