angular 4无法为生产构建

正在尝试ng构建--prod抛出

我尝试删除节点模块，但没有帮助

尝试：

npm安装@angular/material@latest--保存

---

npm安装@angular/cdk@latest--save

它确实更新了那些包，但我仍然遇到了相同的错误try:npm ls--depth=0以列出项目的依赖项。如果依赖项有任何错误，它们应该出现在列表的底部，或者以某种方式加以说明。在过去，我必须安装npm——保存包的特定版本。它说它需要3版，所以您需要npm安装--保存packagename@3也可能是缺少对等依赖，在这种情况下，只需安装所需的软件包即可。无论哪种方法，npm ls--depth=0都是评估依赖关系的快速方法。希望有帮助！它适用于dev build吗使用ng build或ng build--dev时没有相同的错误
