Ionic 4 Production Build - 未加載運行時編譯器錯誤

Question

我正在使用命令ionic build --prod構建用於生產托管的 PWA（使用 Firebase）。 運行生產版本時，我在瀏覽器控制台中收到以下錯誤：

ERROR 錯誤：未加載運行時編譯器

這個問題表明 AoT 是我的問題。 我嘗試運行ionic build --prod --aot=false但問題仍然存在。 我不確定在使用 ionic 時它是否是一個有效參數，我寧願解決這個問題，也不願找到解決方法。

除了錯誤之外，該站點也無法正確加載。 它只是坐在一個純白色的屏幕上。 是什么導致了這個錯誤？

Answer 1

在tsconfig.json你會發現angularCompilerOptions 。 請像這樣添加enableIvy: true ：

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

這適用於 Ionic 4.11.7和 Angular 8.2.14
