使用 Angular 和 Kendo UI 构建 AOT 时出现错误“标识符 'territoryFromName' 已被声明”

Question

最近，我们的包没有任何版本更改，我们的 AOT 构建失败并显示以下错误消息：

块供应商 [初始] [名称].bundle.js 标识符中的错误
'territoryFromName' 已被声明 (13:9)
}

function territoryFromName(name, identity) { var likelySubtags = __WEBPACK_MODULE_REFERENCE__7_636c6472__.supplemental.likelySubtags; var parts = name.split("-");

我们的 package.json 文件如下所示：

我们总是在任何构建之前刷新 node_modules 文件夹（nuke + npm install），并且最近出现了错误（大约在 2018-08-29 上周一）。

自上次构建以来，我们没有对软件包版本进行任何更改。

没有 AOT 的构建仍然可以正常工作，没有任何错误。

如何解决这个错误？

Answer 1

只需从package.json 文件中删除这一行：

"@telerik/kendo-intl": "1.3.2",

---

经过一番研究，我们发现territoryFromName是在kendo-intl相关模块中定义的。

在 kendo 包中似乎存在一些依赖性混淆，看起来 @telerik 包只是重新定义了来自 @progress kendo-angular 更新包的依赖项。

据我了解，这与我们的 @progress/kendo-angular-intl 软件包有冲突

Answer 2

我一直在寻找我的应用程序有什么问题，因为我最近没有进行任何更新，但仍然面临这个错误！

文件内部： \node_modules\@telerik\kendo-intl\dist\es\cldr\territory.js

函数territoryFromName有一个重复声明，其中一个只有name作为参数，另一个有两个参数name和identity

第一个没有用，我只是从文件中删除并保存它，它工作得很好。

PS。我相信他们会很快修复这个错误，但现在这对我有用。

Answer 3

我也遇到了这个错误。我的 package.json 中没有明确安装 @telerik/kendo-intl。它在 @1.4.1 版本中作为 @progress/kendo-angular-intl 的依赖项安装。

我 npm 将 @telerik/kendo-intl 安装到了最新版本 @1.4.2，这解决了我的错误。 @Nour - 如果您查看 @1.4.1 和 @1.4.2 之间的区别，您会注意到 Kendo 团队删除了重复声明。
