In fact Laravel comes with Bootstrap 4 by default. If you take a look at https://github.com/laravel/laravel/blob/master/package.jsonfile (you should have package.json in your project too) you will see line:
事实上，Laravel 默认自带 Bootstrap 4。如果您查看 https://github.com/laravel/laravel/blob/master/package.json文件（您的项目中也应该有 package.json），您将看到以下行：
"bootstrap": "^4.0.0"
what means Bootstrap 4 will be installed.
这意味着将安装 Bootstrap 4。
You should run
你应该跑
npm install
to install all packages and by default it will install Bootstrap 4.
安装所有软件包，默认情况下它将安装 Bootstrap 4。

If you look in the Laravel welcome.blade.php file, you can see some CSS and a link tag that imports a Google Font. This is not to be confused with actually importing Bootstrap 4.
如果您查看 Laravel 的welcome.blade.php 文件，您可以看到一些CSS 和一个导入Google 字体的链接标签。不要将这与实际导入 Bootstrap 4 混淆。
Heres the steps to take to implement Bootstrap 4, and all the other cool things that come with Laravel by default. It already seems as though you've run npm run watchso I'm going to assume you've run that command.
下面是实现 Bootstrap 4 的步骤，以及 Laravel 默认附带的所有其他很酷的东西。看起来你已经运行了，npm run watch所以我假设你已经运行了那个命令。
Simple Steps
简单的步骤
Add a link tag to your head element:
将链接标签添加到您的 head 元素：
<link rel="stylesheet" href="css/app.css">
Add the following at the bottom of your body element:
在 body 元素的底部添加以下内容：
<script src="js/app.js" charset="utf-8"></script>
That should do it for you. But please make sure you've compiled the SCSS files and Javascript files using the npm run watchcommand or else it won't work!
那应该为你做。但是请确保您已经使用该npm run watch命令编译了 SCSS 文件和 Javascript 文件，否则将无法运行！
Cheers!
干杯!
