Question

我有一个使用Bootstrap 4和Bootswatch主题（Lumen）的Angular 6应用。当我使用ng serve在测试环境中编译站点时，样式和主题可以正常工作，而当使用ng build为我的nginx Web服务器进行编译时，样式和主题也可以正常工作。但是，当以Web服务器的生产模式（ng build --prod）进行编译时，基本的Bootstrap样式有效，但是Bootswatch主题显然未加载或无效。该网站看起来像普通的Bootstrap 4。

我在Angular CLI中的安装过程是：

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"
],

杀死我主题的生产模式是怎么回事？我该如何解决？

Answer 1

您可以尝试通过添加styles.css而不是直接在angular.json的styles []下添加内容：

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

肯定是：

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

Answer 3

我知道这是一个较晚的答案，但是公认的答案是错误的。您应该用Bootswatch一替换原来的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，您只需要具备以下条件：

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

Angular 6生产模式会删除Bootswatch主题吗？
