Ionic 4 Production Build - 未加载运行时编译器错误

Question

我正在使用命令 ionic build --prod 构建我的 PWA 以用于生产托管（使用 Firebase）。运行生产版本时，我在浏览器控制台中收到以下错误：

ERROR 错误：未加载运行时编译器

This question 建议我的问题是 AoT。我尝试运行ionic build --prod --aot=false，但问题仍然存在。我不确定在使用 ionic 时它是否是一个有效参数，我宁愿解决问题也不愿找到解决方法。

除了错误之外，该网站也无法正确加载。它只是坐在一个纯白色的屏幕上。是什么导致了这个错误？

Answer 1

在tsconfig.json 中，您将找到angularCompilerOptions。请像这样添加enableIvy: true：

"angularCompilerOptions": {
    "enableIvy": true,
}

这对我有用 Ionic 4.11.7 和 Angular 8.2.14
