ngModuleType.ngModuleDef.id 未定义 - 导入 NguCarousel 模块时的 Angular 8 问题

如何解决ngModuleType.ngModuleDef.id 未定义 - 导入 NguCarousel 模块时的 Angular 8 问题

当我尝试导入 NguCarousel 模块时，我的应用程序中断，因为 ngModuleType.ngModuleDef 未定义。如果我注释掉 NguCarousel 模块的导入，应用程序就可以正常工作。我试过更改包的版本，但没有运气。目前我安装了 v1.5.5 和 Angular 8。

知道为什么这个模块缺少这个属性吗？

js 错误：

解决方法

我今天在相同的角度版本 (v8) 上遇到了同样的错误。这是由于安装了更高版本的 angular material (v12) 引起的，当我注意到我忘记指定版本时，我使用 npm uninstall 命令卸载它然后重新安装正确的版本。这是我遇到错误时的情况。

解决我的问题

关闭 vs 代码
转到文件资源管理器上的项目路径
删除 node_modules 文件夹
再次在 vs code 上打开项目
运行命令 npm i

节点包管理器将为您重新安装具有正确版本的所有包，这应该可以解决问题。
