Question

我最近更新了所有依赖项（纱线升级 - 最新）。

对于翻译，我使用@ ngx-translate。现在，当我构建我的项目（yarn run webpack：build）时，它将语言文件添加到错误的文件夹中，我得到404，因此没有翻译。

所需的结构应为：/target/www/i18n/de.json

当前文件夹结构为：/target/www/target/www/i18n/de.json

现在我的猜测：设置路径时显然有错误（附加./或类似的东西）。

我的问题是：我在哪里可以设置编译语言的放置路径？

我的package.json看起来像这样（jus依赖项部分）：

Answer 1

首先，我在@ngx-translate

中看不到任何package.json个软件包

以下是我的解决方法：

yarn install @ngx-translate/core和。{ @ngx-translate/http-loader
然后您需要定义HttpLoaderFactory方法。为了入门，请将其放在根模块中（可能名为app.module.ts）。请记住首先导入刚刚安装的模块：

import { TranslateModule, TranslateLoader } from '@ngx-translate/core'; import { TranslateHttpLoader } from '@ngx-translate/http-loader';

然后您就可以编辑翻译文件的位置。

export function HttpLoaderFactory(http: Http) { return new TranslateHttpLoader( http, '../target/www/i18n/', // or whatever path you're using '.json' ); }

这应该让你开始。如果您遇到问题，自述文件会有一些有用的示例...... https://github.com/ngx-translate/core/blob/master/README.md

只为偶然遇到同样问题的人：经过几个小时的谷歌搜索，我没有找到改变的原因。但是，我能够通过更改 webpack.common.js 中的以下行来解决这个问题：

    new MergeJsonWebpackPlugin({
        output: {
            groupBy: [
                { pattern: "./src/main/webapp/i18n/en/*.json", fileName: "./i18n/en.json" },
                { pattern: "./src/main/webapp/i18n/fr/*.json", fileName: "./i18n/fr.json" }
                // jhipster-needle-i18n-language-webpack - JHipster will add/remove languages in this array
            ]
        }
    }),

到：

    new MergeJsonWebpackPlugin({
        output: {
            groupBy: [
                { pattern: "./src/main/webapp/i18n/en/*.json", fileName: "../../i18n/en.json" },
                { pattern: "./src/main/webapp/i18n/fr/*.json", fileName: "../../i18n/fr.json" }
                // jhipster-needle-i18n-language-webpack - JHipster will add/remove languages in this array
            ]
        }
    }),

（请注意 fileName 中的路径。）

希望我可以拯救某人在搜索错误时遇到的困难;）

我找到了解决方案。据我了解，您正在使用jhipster。此代码段已在jhipster中进行了测试。只需在app.module.ts中包含此代码（不应保留在app.module.ts中）。据说这是ng-jhispter中的优化。

import {HttpClientModule, HttpClient} from '@angular/common/http';
import {TranslateModule, TranslateLoader} from '@ngx-translate/core';
import {TranslateHttpLoader} from '@ngx-translate/http-loader';

export function HttpLoaderFactory(http: HttpClient) {
    return new TranslateHttpLoader(http, '/app/i18n/');
}

NgModule({
    declarations: [...],
    imports: [
        ...
        HttpClientModule,
        TranslateModule.forRoot({
            loader: {
                provide: TranslateLoader,
                useFactory: HttpLoaderFactory,
                deps: [HttpClient]
            }
        })
    ],

    // The component that loads
        bootstrap: [AppMainComponent]
})
export class AppModule {
}
