javascript - 带 Webpack 的 React-Bootstrap 无法在 React-starter-kit 中运行

Question

请我需要一些帮助，因为我很难在从react-starter-kit模板(https://github.com/kriasoft/react-starter-kit)创建的新项目中使用bootstrap和react-bootstrap。

我对 webpack 还很陌生，所以我不太确定需要做什么才能让它工作。

到目前为止我所做的步骤:

1)我在package.json中包含了react-bootstrap、bootstrap和jquery2)我在主文件中导入了一个react-bootstrap按钮并尝试渲染。它根本没有任何样式渲染。

还需要做什么？

这是 webpack.config:

Answer 1

您需要手动添加引导CSS:

Because React-Bootstrap doesn't depend on a very precise version of Bootstrap, we don't ship with any included css.

More info here

在src/components/Html.js内添加引导样式表

<!-- Latest compiled and minified CSS -->
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/latest/css/bootstrap.min.css">

<!-- Optional theme -->
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/latest/css/bootstrap-theme.min.css">

用法(例如:Home.js)

<Button bsStyle="primary">Default</Button>
<h1>React.js News</h1>
<Alert bsStyle="warning"> Hello </Alert>
