角6制作模式移除Bootswatch主题？

Question

我有一个角形6应用程序使用引导4和一个Bootswatch主题(内腔)。当我使用ng serve在测试环境中编译站点时，样式和主题工作得很好，在用ng build编译nginx时也可以很好地工作。但是，在为when服务器编译生产模式(ng build --prod)时，基本的引导样式可以工作，但是Bootswatch主题显然没有加载或无效。这个网站看起来像普通的香草靴带4。

我使用角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“样式”部分如下：

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

，我的主题被扼杀的生产模式是怎么回事？我该怎么解决呢？

Answer 1

与直接在angular.json中的样式下面添加不同，您可以通过添加styles.css来尝试：

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

我知道这是一个迟来的答案，但接受的答案是错误的。您应该将原始的bootstrap.min.css替换为Bootswatch one。Bootsatch的CSS文件应该取代原来的引导CSS文件。因此，在您的angular.json中只需要：

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

Answer 3

肯定是：

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