Question

我正试图在Heroku上对一个udemy课程的React项目进行生产构建。 我尝试了很多东西来使它工作，但我完全不知道。

从Heroku构建过程的输出。

来自服务器的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"));
  });
