Angular 角度cli错误：找不到模块'@ngtools/json模式'；

我最近在我的项目中运行了npm更新。完成后，每当我尝试运行ng发球时，我都会得到一个

错误：找不到模块“@ngtools/json架构”

然而，在我的node_模块文件中，有一个非常明显的@ngtools文件。我尝试卸载并重新安装angular cli，但仍然收到此错误

任何帮助都将不胜感激。

我发现一个可能的错误：

• 确保运行

  npm update--save

  ，否则不会保存任何更改

如果仍然出现错误，请执行以下步骤：

• rm-rf节点模块

• 删除

  包锁.json

• npm安装

共享您的package.json文件您的依赖项中没有

@ngtools/json schema

。@user184994我以前在依赖项列表中没有它，ng cli运行fine您是否尝试过运行

npm install--save@ngtools/json schema

以查看是否有效？谢谢@austindeveloper的回答。我正在运行windows，所以我必须找到rm和-rf的等价物，但它起作用了！
