IT技术 - Heroku - 部署 React/Express 应用程序并在请求 chunk.js 文件时在控制台中获取“无法加载资源” - 吾爱随笔录

我的 React 应用程序在 Heroku 上构建和部署后，我在控制台中收到这些错误。

Refused to apply style from 'https://radiant-tor-66940.herokuapp.com/index.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled.
Failed to load resource: the server responded with a status of 404 (Not Found) main.3174e036.chunk.js:1

该index.js文件位于/client/build/我的 Heroku 服务器上。这是我的 Express 服务器发送的文件。服务器正在发送这个index.html文件，但文件本身没有找到它需要的资源。

这会导致加载空白应用程序的问题。由于某种原因index.html，没有chunk.js在/client/build/static/js. 他们肯定在那里，我可以确认heroku run bash并检查目录。

当我index.html在浏览器中检查文档时，我可以在底部看到脚本标签调用chunk.js文件的位置/static/js：

这是package.json应用程序的根目录的样子：

  "scripts": {
    "test": "jest",
    "start": "node server/server.js",
    "heroku-postbuild": "cd client && npm install --only=dev && npm install && npm run build"
  },
  "engines": {
    "node": "~9.10.1",
    "npm": "~5.6.0"
  }

这是package.json位于中的 React 应用程序的/client样子：

{
  "name": "client",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "axios": "^0.19.0",
    "lodash": "^4.17.11",
    "react": "^16.7.0",
    "react-dom": "^16.7.0",
    "react-redux": "^6.0.0",
    "react-router-dom": "^4.3.1",
    "react-scripts": "2.1.3",
    "redux": "^4.0.1",
    "redux-thunk": "^2.3.0",
    "styled-components": "^4.1.3"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },
  "eslintConfig": {
    "extends": "react-app"
  },
  "browserslist": [
    ">0.2%",
    "not dead",
    "not ie <= 11",
    "not op_mini all"
  ],
  "proxy": "http://localhost:8000/"
}

这是 Heroku 构建后的文件结构：
