angular - AllowJS在Angular上不起作用

我的角度项目中包含js文件/库，它在我的assets文件夹中。在Angular4或Angular2之前，我在编译器选项中将allowjs设置为true没有问题，但是当我更新到Angular5（cli+typescript）时，它不起作用，它说

error TS5055: Cannot write file '<a path/afile.js>' because it would overwrite input file.

仅包含allowJS（在我的类型文件中没有导入）在ng serve or ng build时触发错误。
此外，删除它成功地服务/构建了我的项目，但我需要允许js。
这是我的tsconfig.app.json

    {
  "extends": "../tsconfig.json",
  "compilerOptions": {
    "allowJs": true,
    "outDir": "../out-tsc/app",
    "baseUrl": "./",
    "module": "es2015",
    "types": []

  },
  "exclude": [
    "test.ts",
    "**/*.spec.ts"
  ]
}

这是我的角度版本+其他信息

我的工作正常
tsconfig.json配置

{
 "compileOnSave": false,
 "compilerOptions": {
 "declaration": false,
 "emitDecoratorMetadata": true,
 "experimentalDecorators": true,
 "module": "commonjs",
 "moduleResolution": "node",
 "outDir": "../dist/out-tsc-e2e",
 "sourceMap": true,
 "target": "es5",
 "allowJs": true,
 "typeRoots": [
   "../node_modules/@types"
 ]
}}
