我正在尝试使用生成器来设置一个express.js服务器。我已经按照文档的说明成功地创建了基本结构。但是如果我尝试运行给定的命令（SET DEBUG=transcriptverificationserver:* & npm start）来启动服务器，我总是得到以下错误：

npm ERR! Missing script: "start"
npm ERR!
npm ERR! Did you mean one of these?
npm ERR!     npm stars # View packages marked as favorites
npm ERR!
npm ERR! To see a list of scripts, run:
npm ERR!   npm run

npm ERR! A complete log of this run can be found in:
npm ERR!     C:\Users\a\AppData\Local\npm-cache\_logs\2022-11-28T22_43_43_285Z-debug-0.log
PS C:\Users\a\Desktop\Verified Transcripts\Webpage> npm start
npm ERR! Missing script: "start"
npm ERR!
npm ERR! Did you mean one of these?
npm ERR!     npm star # Mark your favorite packages
npm ERR!     npm stars # View packages marked as favorites
npm ERR!
npm ERR! To see a list of scripts, run:
npm ERR!   npm run

我认为这是package.json文件中的问题。脚本部分如下所示：

"scripts": {
    "start": "node ./bin/www"
  },

我没有改变任何文件或结构，我只是简单地从文档（https://expressjs.com/en/starter/generator.html）复制命令感谢任何帮助提前
