npm run ionic:build --prod 给出奇怪的错误

Question

当我尝试运行 npm run ionic:build --prod 时，它给了我以下错误：

错误：无法确定类 OverlayPortal 的模块 F:/D/IONIC/quicktask/quicktask-web-froala/node_modules/ionic-angular/umd/components/app/overlay-portal.d.ts！ 将 OverlayPortal 添加到 NgModule 以修复它。无法确定类 IonicApp 的模块 F:/D/IONIC/quicktask/quicktask-web-froala/node_modules/ionic-angular/umd/components/app/app-root.d.ts！添加 IonicApp 到 NgModule 来修复它。无法确定类 ClickBlock 的模块 F:/D/IONIC/quicktask/quicktask-web-froala/node_modules/ionic-angular/umd/components/app/click-block.d.ts！ 将 ClickBlock 添加到 NgModule 以修复它。无法确定幻灯片类的模块 F:/D/IONIC/quicktask/quicktask-web-froala/node_modules/ionic-angular/umd/components/slides/slides.d.ts！添加 滑动到 NgModule 来修复它。

现在，如果我尝试使用以下代码将其包含在 app.module.ts 中：

import { OverlayPortal } from '../../node_modules/ionic-angular/umd/components/app/overlay-portal.d';

@NgModule({
  declarations: [
    OverlayPortal, //for aot compilation

在做ionic serve 之后我得到的错误是 -

模块构建失败：错误：ENOENT：没有这样的文件或目录，打开 'F:\D\IONIC\quicktask\quicktask-web-froala\node_modules\ionic-angular\umd\components\app\overlay-portal。 d.js' 在错误（本机）

如何使用--prod 构建并使用ionic-serve 运行而没有任何错误。

Answer 1

从 URL 中删除“umd”

import { OverlayPortal } from "../../node_modules/ionic-angular/components/app/overlay-portal.d";

这里有更多 => Error: Cannot determine the module for class OverlayPortal in --prod

Answer 2

我解决了我的问题。在我的项目中，我使用了一个过时的模块ion-datepicker。如果您也遇到同样的问题，您可以按照以下步骤查找受感染或过时的模块。

1.第一步：

在您的项目中查找所有文件 from 'ionic-angular/ 一句话，

2。第二步：

如果你发现这个词像 import { xyz } from 'ionic-angular/xyz/abc'

更新那个模块。

如果没有可用的更新，那么您可以删除该模块

npm uninstall ion-datepicker(or your defected module)

在此之后，您需要从 app.module.ts 中删除该模块，以及从那里使用 remove 的任何位置，然后您可以尝试

ionic cordova build android --prod --release

Answer 3

我遇到了同样的错误。对我来说，这是由于 Ionic 导入不一致（一些来自顶级 ionic-angular，一些直接从组件导入，例如 ionic-angular/components/loading/loading-controller）。

Answer 4

您用来导入的文件是type definitions 文件，扩展名为.d.js。

您应该改为从.ts 文件导入。检查文件夹，你应该得到它
