无法在 Github 页面上部署 React App。应用未注入 <div id="app"/>

Question

<!DOCTYPE html>
<html lang = "en">
<head>
<meta charset = "UTF-8">
 <title>My App</title>
 <link href="styles.css" rel="stylesheet"></head>
<body>
  <p>Hello gh-pages!</p>
  <div id="app"></div>
  <script type="text/javascript" src="transformed.js"></script>
</body>
</html>

这是我的 index.html，与 styles.css 和 [= 一起存储在 gh-pages 分支上23=]transformed.js 我从 master 分支上的构建文件夹中复制了它。 gh-pages 分支上没有其他内容。当我导航到 https://krasnokutskiyea.github.io/myProj/ 时，我只看到 Hello gh-pages!，但我的实际 React 应用程序没有被注入 div id="app".控制台中没有错误。任何想法如何解决它？我的 package.json 来自 master 分支：

我的app/index.js:

/* eslint-env node */

import React from 'react'
import ReactDOM from 'react-dom'
import { createStore, compose, applyMiddleware } from 'redux'
import { Provider } from 'react-redux'
import createSagaMiddleware from 'redux-saga'
import { BrowserRouter, Route } from 'react-router-dom'

import allReducers from './reducers/index'
import RootSaga from './sagas/index'
import EntryPage from './containers/EntryPage'


// CREATING STORE AND SAGA
const saga = createSagaMiddleware()
const composeEnchancers = window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__ || compose
const store = createStore(allReducers, 
composeEnchancers(applyMiddleware(saga)))
saga.run(RootSaga)



// RENDERING ROOT COMPONENT
ReactDOM.render(

  <Provider store={store}>
    <BrowserRouter>
      <div>
        <Route exact path="/" component={EntryPage} />
      </div>
    </BrowserRouter>
  </Provider>,

  document.getElementById('app'),
)

Answer 1

问题出在你的router/path。

您的 React 应用程序正在呈现，但您的单一路线与您的 url 路径不匹配：

<Route exact path="/" component={EntryPage} />

这行不通，因为您的应用在 /myProj/。

将您的路线路径更改为 /myProj/ 即可解决问题。

Answer 2

您的 Route 和 path="/" 将无法正常工作，因为您的网页基础是 /myProj。

您可以通过给您的 BrowserRouter 一个 /myProj 的 basename 来解决这个问题：

ReactDOM.render(
  <Provider store={store}>
    <BrowserRouter basename="/myProj">
      <div>
        <Route exact path="/" component={EntryPage} />
      </div>
    </BrowserRouter>
  </Provider>,
  document.getElementById('app'),
)
