「.builders ['browser']」には、必須のプロパティ 'class'が必要です
Npm installを使用して依存関係を正常にインストールした後、サーバーの実行中に次のエラーが発生しました。
Schema validation failed with the following errors: Data path ".builders['browser']" should have required property 'class'.
しばらく検索した後、問題は"@angular-builders/custom-webpack"にあると思います。
プロジェクトは問題なく動作していましたが、誤って削除して再度複製すると、エラーが発生しました。
開発依存関係は次のとおりです。
"devDependencies": {
"@angular-builders/custom-webpack": "latest",

}
そして、これが私のangular.jsonファイルです：
{
"$schema": "./node_modules/@angular/cli/lib/config/schema.json",
"version": 1,
"newProjectRoot": "projects",
"projects": {
"iShop": {
"root": "",
"sourceRoot": "src",
"projectType": "application",
"prefix": "app",
"schematics": {
"@schematics/angular:component": {

}
},
"architect": {

"builder": "@angular-builders/custom-webpack:browser",

],

}
}
}
}
},
"defaultProject": "iShop"
}
そして私のangular CLIバージョンは：7.3.9
私の場合、それは依存バージョンの問題でした。
次の依存関係バージョンを変更しました：
"@angular-builders/custom-webpack": "latest"
"@angular-builders/dev-server": "latest"
に：
"@angular-builders/custom-webpack": "~7.4.3"
"@angular-builders/dev-server": "~7.3.1"
この行を変更する必要があると思います
"builder": "@angular-builders/custom-webpack:browser"
何かに
"builder": "@angular-devkit/build-angular:browser",
また、package.jsonのcustom-webpack設定を確認してください。ビルダーは角度から来るデフォルトの設定を使用する必要があります
以下は私の設定です
