问题描述
我正在关注应该与 Angular 7 一起使用的Pro Angular 6"一书.我是这样开始项目的；
I'm following the "Pro Angular 6" book which should work with Angular 7. I start the project like so;
安装angular cli
Install angular cli
sudo npm install -g @angular/cli
注意:这里安装了 cli 工具的 7.3.0 版
NOTE: This installed version 7.3.0 of the cli tool
现在安装 TODO 应用
Now install the TODO app
ng new todo
cd todo
ng serve --port 3001 --open
这有效，然后我添加引导程序
This works, then I add in bootstrap
npm install bootstrap@4.1.1
我将以下内容添加到样式中
And I add the following to styles
"styles": [
"src/styles.css",
"node_modules/bootstrap/dist/css/bootstrap.min.css"
],
现在，当我为项目提供服务时，出现以下错误；
Now when I serve the project I get the following error;
$ ng serve --port 3001 --open
