错误:尝试注入未知注入：'service:i18n‘

Question

我对ember-i18n有以下问题：

Error: Attempting to inject an unknown injection: 'service:i18n'
at Registry.validateInjections (ember.debug.js:2303)
at ember.debug.js:1538
at runInDebug (ember.debug.js:5813)
at Object.runInDebug (ember.debug.js:17396)
at instantiate (ember.debug.js:1532)

at Class.lookup (ember.debug.js:32564)
at Class._internalGetHandler (router-ext.js:107)
at Class._getHandlerForEngine (router-ext.js:84)

我在ember引擎中使用ember-i18n插件。我的i18n初始化器addon/instance-initializers/i18n.js

export default {
name: 'i18n',

initialize: function(applicationInstance) {
    const i18nService = applicationInstance.lookup('service:i18n');
    i18nService.set('defaultLocale', window.I18n.defaultLocale);
    i18nService.set('locale', window.I18n.locale);
}
};

在我的索引路由(routes/index.js)中，我有以下代码：

import Ember from 'ember';

export default Ember.Route.extend({
i18n: Ember.inject.service(),

actions: {
    didTransition() {
        Ember.run.scheduleOnce('afterRender', this, function() {
            console.log(this.get('i18n').t('error_empty_user_data'));
            // ....
        });
    }
}
});

如何声明i18n服务？

我使用ember-18n 4.5.0版本和2.10.0 ember-cli版本。

初始化器应该在i18n one之后运行。

export default {
  name: 'i18n',
  after: ['ember-i18n'],

  initialize: function(applicationInstance) {
    const i18nService = applicationInstance.lookup('service:i18n');
    i18nService.set('defaultLocale', window.I18n.defaultLocale);
    i18nService.set('locale', window.I18n.locale);
  }
};
