部署到 heroku path="/" path="/favicon.ico" 的问题

Question

希望有人可以帮助我解决将我的 React 应用程序推送到 heroku 时遇到的问题。 heroku 日志反复显示以下错误。

at=error code=H10 desc="App crashed" method=GET path="/" host=jp-portfolio.herokuapp.com request_id=4841ef14-b2f2-4ae7-82d7-d47abf123db7 fwd="67.188.208.208" dyno= connect= service= status=503 bytes= protocol=https 2020-04-02T06:42:02.631967+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/favicon.ico" host=jp-portfolio.herokuapp.com request_id=552909aa-ff34-4a4d-91cc-c817938b39b7 fwd="67.188.208.208" dyno= connect= service= status=503 bytes= protocol=https

对我来说，它似乎不喜欢我在 app.js 文件中定义路由的方式，所以我更改了 app.js 文件并添加了路由器文件但它对我不起作用。

还有这个

App.js 文件

import React, { Component } from 'react'

class App extends Component {
static propTypes = {
  children: PropTypes.node
}

render() {
  const { children } = this.props
  return (
    <div>
      {children}
    </div>
  )
}
}

export default App

我的包裹JSON

  "private": false,
  "dependencies": {

      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }

Router.js

import React from 'react';
import { BrowserRouter as Router, Route} from "react-router-dom";
import Portfolio from "./pages/portfolio";
import About from "./pages/about"
import { useRouterHistory, Router } from 'react-router'
import { createHistory } from 'history'

const history = useRouterHistory(createHistory)({
    basename: '/test'
  })

export default <Router history={history} >
  <Route path="/" component={App}>
    <IndexRoute component={Portfolio}/>
    <Route path="/about" component={About}/>
  </Route>
</Router>

在本地运行。

有没有人遇到过类似的问题并且知道我可以如何解决这个问题？任何帮助将不胜感激！

Answer 1

https://blog.heroku.com/deploying-react-with-zero-configuration

嘿，你经历过这个吗？我认为如果您使用的是 Heroku CLI，则需要在部署期间添加 -b 标记以添加自定义构建包。

也类似这个问题

编辑：所以我尝试将示例 React 应用程序部署到 heroku 并遇到了类似的问题。问题是，当您使用 Create-react-app 生成 React 应用程序时，它会自动添加构建配置。现在 heroku 构建应用程序并尝试为构建的应用程序提供服务。因此，它将无法按预期路由应用程序。要解决这个问题，您将不得不使用构建包以及告诉 heroku 如何提供文件的项目，或者您必须将后端和前端分开（使用节点的前端反应和后端快速服务器）。

编辑 2：根据@IvanAracki 的建议添加了一些引号

Thanks to the zero-config foundation of create-react-app, the idea of zero-config deployment seemed within reach. Since these new apps all share a common, implicit architecture, the build process can be automated and then served with intelligent defaults. So, we created this community buildpack to experiment with no-configuration deployment to Heroku.

npm install -g create-react-app
create-react-app my-app
cd my-app
git init
heroku create -b https://github.com/mars/create-react-app-buildpack.git
git add .
git commit -m "react-create-app on Heroku"
git push heroku master
heroku open

使用 buildpack docs.
