reactjs - 错误 : Failed to load plugin import: Cannot find module 'eslint-plugin-import' when deploying a create-react-app

Question

我是 create-react-app 的新手。我刚刚用 redux 做了一个快速设置和 react-router-dom使用 yarn build 在我的计算机上很好地构建，但是当推送到 Scalingo 或 Heroku 时，构建失败并出现以下错误:

 ./src/index.jsx
       Error: Failed to load plugin import: Cannot find module 'eslint-plugin-import'
       Referenced from:
       at Array.forEach (<anonymous>)
       at Array.reduceRight (<anonymous>)

我没有做任何定制部署，只是推到生产。
这是完整的部署日志:

       Some possible problems:
        
       - A module may be missing from 'dependencies' in package.json
       http://doc.scalingo.com/languages/javascript/nodejs#ensure-youre-tracking-all-your-dependencies
        
       - This module may be specified in 'devDependencies' instead of 'dependencies'

 !     An error occured during buildpack compilation
 !   Error deploying the application
 !   → Invalid return code from buildpack 

这是我的 package.json :

  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "@sentry/browser": "^4.5.4",
    "prop-types": "^15.7.1",
    "react": "^16.8.1",

    "react-scripts": "2.1.5",
    "redux": "^4.0.1",

    "eject": "react-scripts eject"
  },
  "eslintConfig": {
    "extends": "react-app"
  },
  "browserslist": [
    ">0.2%",
    "not dead",
    "not ie <= 11",
    "not op_mini all"
  ],
  "devDependencies": {
    "eslint-config-airbnb": "^17.1.0",
    "eslint-plugin-import": "^2.16.0",
    "eslint-plugin-jsx-a11y": "^6.2.1",
    "eslint-plugin-react": "^7.12.4"
  }
}

我不明白为什么我会使用 eslint及其在我的生产代码中的插件，以及如何解决这个问题。你能帮我吗？

问题是添加 devDependencies没有在生产中安装。覆盖 eslint 配置没问题，但所有需要的包都必须添加到主 dependencies .
