【问题讨论】：

您是否尝试过重新安装节点模块？

标签： angular

【解决方案1】：

我认为您应该遵循以下步骤。执行以下步骤后，错误将得到解决。

要遵循的步骤：

删除 node_modules 文件夹。
删除 package-lock.json 文件。
运行 npm cache clean --force
运行 npm install --save @angular/material @angular/cdk

【解决方案2】：

看来我已经找到答案了。

所以在运行 npm install 命令后，我收到了警告，然后我在 ng 服务之后运行 npm audit fix 命令。所以我得到了上面提到的错误。

因此下次我先运行 - npm install 然后 - npm 开始

这次我没有出错，我可以看到项目了。
