在Heroku中部署react app时，我遇到以下错误。我删除了package-lock.json，并再次安装了npm，但我再次遇到相同的错误。有人能告诉我如何解决这个错误吗？
以下是已安装的依赖项：

"dependencies": {
    "@emotion/react": "^11.9.0",
    "@emotion/styled": "^11.8.1",
    "@material-ui/core": "^4.12.4",
    "@mui/icons-material": "^5.8.3",
    "@mui/material": "^5.8.3",
    "@testing-library/jest-dom": "^5.16.4",
    "@testing-library/react": "^13.1.1",
    "@testing-library/user-event": "^13.5.0",
    "axios": "^0.27.2",
    "cors": "^2.8.5",
    "express": "^4.18.1",
    "multer": "^1.4.4",
    "mysql2": "^2.3.3",
    "path": "^0.12.7",
    "react": "^18.0.0",
    "react-dom": "^18.0.0",
    "react-hook-form": "^7.31.2",
    "react-router-dom": "^6.3.0",
    "react-scripts": "^5.0.1",
    "react-tweet-embed": "^2.0.0",
    "sequelize": "^6.20.1",
    "web-vitals": "^2.1.4"
  },

添加“预安装”：“npx npm-force-resolutions”和“heroku建置后”：“npm install”到package.json文件，如下所示，帮助我解决了这个问题

"scripts": {    "start": "react-scripts start",
                "build": "react-scripts build",
                "test": "react-scripts test", 
                "eject": "react-scripts eject",     
                "preinstall": "npx npm-force-resolutions",
                "heroku-postbuild": "npm install"   }
