以下是我的 package.json

  {
      "name": "bot",
      "version": "1.0.0",
      "description": "",
      "main": "index.js",
      "scripts": {
        "start": "nodemon index.js"
      },
      "author": "",
      "license": "ISC",
      "dependencies": {
        "express": "^4.17.1",
        "nodemon": "^2.0.2"
      }
    }

上面的包 json 有一个执行 nodemon index.js 的脚本启动，但每次我执行 npm start 时，我都会收到上述错误，搜索有关如何解决它的线索，但在 stackover 流或其他来源上没有结果。

我想你在remove(item) 之前忘记了关键字function。

const async function remove(item) {
  // Your function code here
}

或使用箭头函数：

cons remove = async (item) => {
  // Your function code here
}
