Question

我正在尝试在Rails应用程序的Ruby上运行测试，但是当我键入rails test时，它返回此错误：

/.rbenv/versions/2.7.0/lib/ruby/gems/2.7.0/gems/pg-1.2.3/lib/pg.rb:58:in `initialize': could not connect to server: No such file or directory (PG::ConnectionBad)
Is the server running locally and accepting
connections on Unix domain socket "/tmp/.s.PGSQL.5432"?

似乎它需要gem pg或PostgresSQL数据库，但我想在sqlite3数据库中运行它，所以我检查了我的Gemfile和database.yml

database.yml

default: &default
  adapter: postgresql
  encoding: unicode

development:
  adapter: sqlite3
  database: db/development.sqlite3
  pool: 5
  timeout: 5000
  #database: db/development.sqlite3

test:
  adapter: sqlite3
  database: db/test.sqlite3
  pool: 5
  timeout: 5000


production:
  <<: *default
  database: db/production.sqlite3

我试图运行rails db：migrate和rails db：create db direcotry中存在两个sqlite数据库，还有其他我想念的东西吗？谢谢

Rails测试失败无法连接到服务器：没有这样的文件或目录（PG :: ConnectionBad）
