Javascript 如何使用物料界面和React路由器为React应用程序提供服务

我开发了一个应用程序，主要组件是React+材质UI+React路由器。这是我的完整

包。json

：

{
  "name": "trader-ui",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "@material-ui/core": "^3.2.0",
    "@material-ui/icons": "^3.0.1",
    "@stomp/stompjs": "^5.0.0",
    "axios": "^0.18.0",
    "classnames": "^2.2.6",
    "prop-types": "^15.6.2",
    "react": "^16.5.2",
    "react-dom": "^16.5.2",
    "react-router-dom": "^4.3.1",
    "react-scripts": "2.0.4"
  },
  "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:8080"
}

这是：

但是，当我尝试为生产构建服务时：

$ npm run build
$ npm install -g serve
$ serve -s build

看起来：

有人能告诉我生产构建出了什么问题吗？

感谢@giorgim的建议。这是正确的。使用材质UI常见问题解答解决此问题：

我的样式设置代码位于

withRoot.js

：

import React from 'react';
import {createMuiTheme, MuiThemeProvider} from '@material-ui/core/styles';
import CssBaseline from '@material-ui/core/CssBaseline';

const theme = createMuiTheme({
    typography: {
        useNextVariants: true,
    },
});

function withRoot(Component) {
  function WithRoot(props) {
    return (
      <MuiThemeProvider theme={theme}>
        <CssBaseline />
        <Component {...props} />
      </MuiThemeProvider>
    );
  }

  return WithRoot;
}

export default withRoot;

当然，您应该事先安装

react jss

：

$ npm install react-jss

如果查看开发人员工具的“网络”选项卡，是否会看到任何错误？请检查是否有帮助：@Tholle，无错误

import React from 'react';
import { create } from 'jss';
import JssProvider from 'react-jss/lib/JssProvider';
import {
    MuiThemeProvider,
    createMuiTheme,
    createGenerateClassName,
    jssPreset,
} from '@material-ui/core/styles';
import CssBaseline from '@material-ui/core/CssBaseline';

const theme = createMuiTheme({
    typography: {
        useNextVariants: true,
    },
});

const jss = create(jssPreset());
const generateClassName = createGenerateClassName();

function withRoot(Component) {
  function WithRoot(props) {
    return (
        <JssProvider jss={jss} generateClassName={generateClassName}>
            <MuiThemeProvider theme={theme}>
                <CssBaseline />
                <Component {...props} />
            </MuiThemeProvider>
        </JssProvider>
    );
  }

  return WithRoot;
}

export default withRoot;

$ npm install react-jss
