是否有任何配置设置可以删除这些空注释和空格？

我的构建命令是 ng build --environment prod --progress false --target production 和 tsconfig 是：

{
    "compileOnSave": false,
    "compilerOptions": {
        "alwaysStrict": true,
        "baseUrl": "/",
        "emitDecoratorMetadata": true,
        "experimentalDecorators": true,
        "forceConsistentCasingInFileNames": true,
        "lib": [ "es2015", "dom" ],
        "module": "es2015",
        "moduleResolution": "node",
        "newLine": "CRLF",
        "noFallthroughCasesInSwitch": true,
        "noImplicitAny": true,
        "noImplicitReturns": true,
        "noUnusedLocals": true,
        "noUnusedParameters": false,
        "outDir": "./dist/out-tsc",
        "removeComments": true,
        "skipDefaultLibCheck": true,
        "skipLibCheck": true,
        "strictNullChecks": true,
        "target": "es5",
        "typeRoots": [ "./node_modules/@types" ]
    }
}

@angular/cli：1.0.4

节点：7.2.1

操作系统：win32 x64

谢谢。
