我正在尝试在我的 Angular 应用程序中导入 ngx Bootstrap 日期选择器，为此我遵循了以下步骤
到 npm 安装 ngx-bootstrap
npm install ngx-bootstrap --save
安装引导程序 3
npm install bootstrap@3 --save
在 angular-cli.json 文件中，并在样式属性中指定引导样式表 (bootstrap.min.css) 的路径
“样式”：[“../node_modules/bootstrap/dist/css/bootstrap.min.css”，“styles.css”]
在 Angular 中使用 ngx-bootstrap 日期选择器：
在 app.module.ts 文件中，导入 BsDatepickerModule
从 'ngx-bootstrap/datepicker' 导入 { BsDatepickerModule }；
在 html 中使用
bs日期选择器
类="表单控制" />
在 .angular-cli.json 文件中包含对 bs-datepicker.css 文件的引用。
“样式”：[“../node_modules/bootstrap/dist/css/bootstrap.min.css”，“../node_modules/ngx-bootstrap/datepicker/bs-datepicker.css”，“styles.css”]
但我在运行 Angular 应用程序时遇到错误
ERROR in multi ../node_modules/bootstrap/dist/css/bootstrap.min.css../node_modules/ngx-bootstrap/datepicker/bs-datepicker.css ./src/styles.css
Module not found: Error: Can't resolve '/Users/user/Projects/node_modules/bootstrap/dist/css/bootstrap.min.css'在 '/Users/user/Projects/CRUD' 中的错误 ../node_modules/bootstrap/dist/css/bootstrap.min.css ../node_modules/ngx-bootstrap/datepicker/bs-datepicker.css ./src/样式.css
Module not found: Error: Can't resolve '/Users/user/Projects/node_modules/ngx-bootstrap/datepicker/bs-datepicker.css'在“/用户/用户/项目/CRUD”中
我将所有代码信息放在下面-：
