【问题描述】：
我正在尝试在 udemy 课程 React 项目的 Heroku 上进行生产构建。我已经尝试了很多方法来让它发挥作用，但我完全不知所措。
Heroku 构建过程的输出：
-----> 检测到 Node.js 应用程序
-----> 创建运行环境
NPM_CONFIG_LOGLEVEL=error NODE_ENV=production NODE_MODULES_CACHE=true NODE_VERBOSE=false-----> 安装二进制文件 引擎.node（package.json）：12.17.0 engine.npm (package.json): 6.14.5
Resolving node version 12.17.0... Downloading and installing node 12.17.0... Bootstrapping npm 6.14.5 (replacing 6.14.4)... npm 6.14.5 installed-----> 恢复缓存 由于 node、npm、yarn 或 stack 的版本发生变化，缓存目录未恢复 此版本的模块安装可能需要更长的时间
-----> 安装依赖 安装节点模块（package.json）

来自服务器 index.js：
if (process.env.NODE_ENV === 'production') {
// Express will serve production assets
app.use(express.static('client/build'));
// Express will serve index.html file if it doesn't recognise the route
const path = require('path');
app.get('*', (req, res) => {
res.sendFile(path.resolve(__dirname, 'client', 'build', "index.html"));
