Heroku：无法解决 Sequelize

Question

我正在尝试将旧项目重新部署到 Heroku 并在推送后遇到错误：

Unable to resolve sequelize package in /app

，然后运行命令

heroku run npx sequelize-cli db:migrate

。

FWIW，自从我上次毫无问题地部署它以来，大约一年内我没有对存储库进行任何更改。我最近在 package.json 中添加了

engines

来解决推送错误，但这是唯一的更改。

我在这个仓库中也没有

/app

目录，所以我不确定它来自哪里。

我的package.json：

  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "sequelize": "sequelize",
    "sequelize-cli": "sequelize-cli",
    "start": "per-env",
    "start:development": "nodemon -r dotenv/config ./bin/www",
    "start:production": "node ./bin/www"
  },

  },
  "devDependencies": {

  }
}```

这是通过运行修复的

heroku run npm run sequelize-cli db:migrate
