Angular：primeng 中的样式即使列在 styles.scss 中也不起作用

Question

我已将 primeng 添加到我的 Angular 项目中。但样式不起作用。

我已将样式放入 style.scss 和 angular.json 中。但我总是做服务它不起作用

我的styles.scss：

@import '../node_modules/primeng/resources/themes/lara-light-blue/theme.css';
@import '../node_modules/primeicons/primeicons.css';
@import '../node_modules/primeng/resources/primeng.min.css';

我完整的 angular.json： 我必须为代码提供更多详细信息才能保存它，所以我在这里这样做。

Answer 1

我过去经常遇到这个问题。

唯一对我有用的是在我的项目中使用不同的 primeng 版本。尝试使用不同的版本，它适用于其中一个。

Answer 2

如果您的项目中包含 bootstrap.css，则在新版本中 primeng 和 bootstrap 之间会发生冲突。
