Nativescript在错误的地方寻找Nativescript-主题-核心？

Question

我忙于一个非常简单的条形码扫描器应用程序，并得到一个奇怪的错误后，该应用程序被部署到一个genymotion模拟器…它似乎在错误的地方寻找核心主题？你知道为什么会发生这种情况吗?我怎么才能修复它呢？

我的错误：

my app.css:

@import 'nativescript-theme-core/css/core.dark.css';

and in my app.component.css:

    styleUrls: ['./app.css']

在您的app.css中，您应该有

@import 'nativescript-theme-core/css/core.dark.css';

并在您的app.component.ts中删除对app.css的显式调用。这是不必要的，因为默认情况下，app.css中的样式将在应用程序中全局可见。详情请参见this comment。
