Angular 6带bootstrap 4.1无法加载

Question

我似乎无法通过angular.json文件加载bootstrap

但是,与此问题类似,没有任何引导程序会加载.但是,ng build和ng serve似乎没有报告任何问题.它只是然后我浏览到页面,显然没有任何风格.
Bootstrap 4.1.1 Navbar不使用Angular 6

[ 注意 ]回滚到Bootstrap@3.3.7似乎工作正常

我之前遇到过这个问题,解决办法是制作@import'../node_modules/bootstrap/dist/css/bootstrap.css'; 在任何代码顶部的style.css文件中.所以bootstrap会成功加载
