Question

我正在尝试将Bootstrap4用于我的一个项目;但是，当我在本教程（https://medium.com/codingthesmartway-com-blog/building-an-angular-5-project-with-bootstrap-4-and-firebase-4504ff7717c1）之后使用angular-cli设置我的项目时，我在终端中收到此错误：

ERROR in ./node_modules/css-loader?{"sourceMap":false,"importLoaders":1}!./node_modules/postcss-loader/lib?{"ident":"postcss","plugins":[null,null,null],"sourceMap":false}!./node_modules/bootstrap/dist/css/bootstrap.css

3：10-186 @ ./src/styles.css @ multi ./src/styles.css

我之前使用过Bootstrap，所以我不知道一周前发布的新测试版是否存在问题。

谢谢！
