步骤 1.
Inside .angular-cli.json file
"styles": [
"styles.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 bootstrap
@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。
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"
],
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 bootstrap。
删除此行后,您将失去 bootstrap 提供的更好的前端外观。
如果你也想继续体验bootstrap,请先安装bootstrap。
要安装 bootstrap,请在您的终端中执行此命令 npm install bootstrap --save
然后将 angular.json 更改如下
"styles": [
"node_modules/bootstrap/dist/css/bootstrap.min.css",
"styles.css"]
将 bootstrap 文件放在样式数组列表的顶部很重要。
希望一切都好。为编码加油:)
