使用 npm install 成功安装依赖项后，运行服务器时出现以下错误：

Schema validation failed with the following errors: Data path ".builders['browser']" should have required property 'class'.

搜索了一段时间后，我认为问题出在"@angular-builders/custom-webpack".

该项目运行良好，但我不小心将其删除并再次克隆它，然后出现错误。

这是开发依赖项：

"devDependencies": {
    "@angular-builders/custom-webpack": "latest",
    "@angular-builders/dev-server": "latest",
    "@angular-devkit/build-angular": "~0.13.6",
