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

Question

当我尝试导入 NguCarousel 模块时，我的应用程序因ngModuleType.ngModuleDef未定义而中断。如果我注释掉 NguCarousel 模块的导入，该应用程序可以正常工作。我尝试过更改软件包的版本，但没有成功。目前我已经随 Angular 8 安装了 v1.5.5。

有什么想法为什么这个模块缺少这个属性吗？

js错误：

Answer 1

我今天对于相同的角度版本（v8）遇到了相同的错误。这是由于安装了更高版本的角度材料（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。当我发生错误时。

我的问题的解决方案

1. 关闭 VS 代码
2. 转到文件资源管理器上的项目路径
3. 删除node_modules文件夹
4. 再次在 VS Code 上打开项目
5. 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。
