我收到了这个错误

Cannot parse tsconfig.base.json: PropertyNameExpected in JSON at position 891

在CLI上运行nx g @nrwl\angular:lib libName时

我的tsfig.base.json

{
  "compileOnSave": false,
  "compilerOptions": {
    "rootDir": ".",
    "sourceMap": true,
    "declaration": false,
    "moduleResolution": "node",
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "importHelpers": true,

      "@portal/*": ["apps/portal/src/app/*"],
    }
  },
  "exclude": ["node_modules", "tmp"]
}

当我运行时，我收到错误Cannot parse tsconfig.base.json: PropertyNameExpected in JSON at position 891。

当我尝试运行npx nx g @nrwl/angular:lib libName或nx g @nrwl/angular:lib时，也会发生同样的情况

我正在使用VScode编写代码，tsconfig.base.json中没有错误警告(lint
