我使用了react-router-dom并构建了我的react-app。当我将其部署到服务器上时，我得到一个空白页面，并且控制台是空的。

我的 App.js 是:

import React, { Component } from 'react';
import { Route, Switch, BrowserRouter} from 'react-router-dom';
import Agenda from './components/Agenda/Agenda';
import Planning from './components/Planning/Planning';
class App extends Component {
  render() {
    return (
      <div>
        <BrowserRouter  basename="/">
          <Switch>
            <Route exact path="/"  component={Agenda} />
            <Route path="/planning" component={Planning} />
          </Switch>
        </BrowserRouter>
      </div>
    );
  }
}

export default App;

我的index.js是:

import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';

ReactDOM.render(
        <App/>
, document.getElementById('root'));

我的index.html:

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8" />
    <link rel="shortcut icon"  href="favicon.ico">
    <meta

    <div id="root"></div>
    <script src="https://unpkg.com/react@16.0.0/umd/react.production.min.js"></script>
  </body>
</html>

在我的 package.json 中，我有:

"homepage": "."

当我将我的主页更改为https://dev.test.com/React并且 当我运行它时，我得到一个空白页面，例如我部署的地址是: https://dev.test.com/React/ 它不是公开的。当我运行 serve-s build 时，控制台上出现空白屏幕，我得到:

我的生产index.html是:

如何修复它？

最佳答案

尝试将 BrowserRouter 上的 basename="/" 更改为 basename="/React"。如果在子目录中使用，react-router 需要这个。

来自 react-router docs :

basename: The base URL for all locations. If your app is served from a sub-directory on your server, you'll want to set this to the sub-directory. A properly formatted basename should have a leading slash, but no trailing slash.

同时将 package.json 中的 homepage 更改为您的生产目标的 url。 homepage="." 意味着它将在服务器根目录中的每个域上运行(也是默认行为)。

来自 React docs regarding deployment :

By default, Create React App produces a build assuming your app is hosted at the server root. To override this, specify the homepage in your package.json, for example:

"homepage": "http://mywebsite.com/relativepath",

This will let Create React App correctly infer the root path to use in the generated HTML file.
