我已经将ngx Bootstrap安装到我的Angular应用程序中以使用日期选择器
现在我在运行 Angular 应用程序时遇到错误
我将错误的详细信息放在下面
多错误../node_modules/bootstrap/dist/css/bootstrap.min.css ../node_modules/ngx-bootstrap/datepicker/bs-datepicker.css ./src/styles.css
找不到模块：错误：无法解析"/Users/user/Projects/node_modules/bootstrap/dist/css/bootstrap.min.css" 在"/用户/用户/项目/CRUD"中 多错误../node_modules/bootstrap/dist/css/bootstrap.min.css ../node_modules/ngx-bootstrap/datepicker/bs-datepicker.css ./src/styles.css

您正在从错误的位置导入css文件。
更新angular.json文件：
"styles": [
"node_modules/bootstrap/dist/css/bootstrap.min.css",
"node_modules/ngx-bootstrap/datepicker/bs-datepicker.css",
"src/styles.css"
],
第1 步。
Inside .angular-cli.json file
"样式"：[ "样式.css"， "../node_modules/bootstrap/dist/css/bootstrap.min.css" ]
删除"../node_modules/bootstrap/dist/css/bootstrap.min.css">
第 2 步。
Go to styles.css
通过添加此行导入引导程序
@import "~bootstrap/dist/css/bootstrap.css";
这些步骤解决了我在构建过程中遇到的错误。
请从angular.json文件中删除行"node_modules/bootstrap/dist/css/bootstrap.min.css"。这将修复您的错误。
此行用于引导。
删除此行时，您将失去引导程序提供的更好的前端外观。
如果您也想继续体验引导程序，请先安装引导程序。
要安装引导程序，请在终端npm install bootstrap --save中触发此命令
然后按如下方式更改 Angular.json
"styles": [
"node_modules/bootstrap/dist/css/bootstrap.min.css",
"styles.css"]
将引导程序文件保留在样式数组列表的顶部非常重要。
希望一切都好。欢呼编码:)
