Angular6制作模式去除Bootswatch主题？

Question

我有一个 Angular 6 应用程序，使用 Bootstrap 4 和一个 Bootswatch 主题 (Lumen)。当我在我的测试环境中使用 ng serve 编译站点时，样式和主题工作正常，并且在使用 ng build 为我的 nginx 网络服务器编译时也工作正常。但是，当在网络服务器的生产模式 (ng build --prod) 下编译时，基本的 Bootstrap 样式可以工作，但 Bootswatch 主题显然未加载或无效。该网站看起来很普通 Bootstrap 4.

我使用 Angular CLI 的安装过程是：

npm install --save bootstrap
npm install --save @ng-boostrap/ng-bootstrap
npm install bootswatch

我的angular.json的"styles"段如下：

"styles": [
  "node_modules/bootstrap/dist/css/bootstrap.min.css",
  "node_modules/bootswatch/dist/lumen/bootstrap.min.css",
  "src/styles.css"
],

杀死我的主题的生产模式是怎么回事？我该如何解决？

Answer 1

不是直接在 angular.json 中的样式 [ ] 下添加，您可以尝试在 styles.css 中添加：

styles.css

@import "../node_modules/bootstrap/dist/css/bootstrap.min.css";
@import "../node_modules/bootswatch/dist/lumen/bootstrap.min.css";

angular.json

"styles": [
  "styles.css"
],

Answer 2

当然是：

"styles": [
   "src/styles.css"
],

Answer 3

我知道这是一个迟到的答案，但接受的答案是错误的。您应该用 Bootswatch 替换原来的 bootstrap.min.css。 Bootsatch 的 CSS 文件应该替换原始的 bootstrap CSS 文件。因此，在您的 angular.json 中，您只需要：

"styles": [
  "node_modules/bootswatch/dist/lumen/bootstrap.min.css",
  "src/styles.css"
],
