Question

将应用程序迁移到Nativescript6（自动迁移）后出现此问题。现在，翻译无法正常进行，在启动时在控制台中，我会看到这种错误：

JS: ERROR SyntaxError: Unexpected end of JSON input

但我不确定该问题来自何方。

我在此工具中运行lang json文件，结果很好：https://www.jslint.com/

我的package.json是：

  "nativescript": {
    "id": "com.company.app",
    "tns-ios": {

我的app.module.ts：

import { HttpClientModule } from "@angular/common/http";
import { NgModule, NO_ERRORS_SCHEMA } from "@angular/core";
import { NativeScriptLoader } from "@danvick/ngx-translate-nativescript-loader";
import { TranslateLoader, TranslateModule  } from "@ngx-translate/core";
import { TNSCheckBoxModule } from "@nstudio/nativescript-checkbox/angular";
import { AngularFontAwesomeModule } from "angular-font-awesome";
import { NativeScriptModule } from "nativescript-angular/nativescript.module";
import { NativeScriptUISideDrawerModule } from "nativescript-ui-sidedrawer/angular";
import { AppRoutingModule } from "./app-routing.module";
import { AppComponent } from "./app.component";

export function createTranslateLoader() {
    return new NativeScriptLoader("./assets/i18n/", ".json");
}

@NgModule({
    bootstrap: [
        AppComponent
    ],
    imports: [
        AppRoutingModule,
        HttpClientModule,
        NativeScriptModule,
        AngularFontAwesomeModule,
        NativeScriptUISideDrawerModule,
        TNSCheckBoxModule,
        TranslateModule.forRoot({
            loader: {
                provide: TranslateLoader,
                useFactory: createTranslateLoader
            }
        })
    ],
    exports: [
        TranslateModule,
        TNSCheckBoxModule
    ],
    declarations: [
        AppComponent
    ],
    schemas: [
        NO_ERRORS_SCHEMA
    ]
})
export class AppModule { }

并且json文件位于´/ assets / i18n / en.json´（外部应用程序文件夹）中

一件奇怪的事情是，当我使用调试器进行检查时，在chrome控制台的文件浏览器中，en.json文件为空，就好像没有从资产文件中复制文件一样。

在迁移到nativescript 6.0之前，这是完美的工作方式

Answer 1

您必须在webpack.config.js中更新CopyWebpackPlugin以包含资产文件夹

// Copy assets to out dir. Add your own globs as needed.
new CopyWebpackPlugin([
  { from: { glob: "fonts/**" } },
  { from: { glob: "**/*.jpg" } },
  { from: { glob: "**/*.png" } },
  { from: { glob: "assets/**" } }
], { ignore: [`${relative(appPath, appResourcesFullPath)}/**`] }),

使用Angular8迁移到Nativescript6后ngx-translate无法正常工作
