錯誤：數據庫“dbName”不存在 Node.js PostgreSQL

Question

我剛從 Node.js 開始，我正在關注本教程https://dev.to/glaucia86/developing-a-crud-node-js-application-with-postgresql-4c9o

按照建議設置.env文件時

DATABASE_URL=postgres://{db_username}:{db_password}@{host}:{port}/{db_name}

所以

DATABASE_URL=postgres://vinnytwice:pass@localhost:5432/fixit

當使用 Postman 發送 Post 請求時，我使用npm start命令啟動服務器，我在控制台中收到錯誤消息：

vinnytwice@Vinnys-iMac fixit_server_node % npm start

> fixit_server_node@1.0.0 start
> node server.js

App executing to port  3000
error: database "vinnytwice" does not exist

    at Socket.Readable.push (node:internal/streams/readable:227:10)
    at TCP.onStreamRead (node:internal/stream_base_commons:190:23)

我究竟做錯了什么？ 非常感謝。

終於找到問題了， .env文件不在項目的根目錄下。
