Question

我正在尝试运行yarn start并遇到以下错误：

?  /User/platform/src/containers/App.js: Cannot resolve dependency 'core-js/modules/es6.array.iterator'

这是我的package.json：

      "\\.(scss|css|less)$": "identity-obj-proxy"
    }
  }
}

这是怎么回事？我假设我使用了其中一个软件包的错误版本？我已经卸载并重新安装了几次软件包，但这似乎没有什么作用。

我通过 npm 下载了 core-js@3.6.5 并查看了以下路径：

<块引用>

核心js/模块

modules 目录不包含文件 es6.array.iterator.js，但它包含 es.array.iterator。< /p>

尝试将受影响文件中的路径 'core-js/modules/es6.array.iterator.js' 更改为 'core-js/modules/es.array.iterator.js'。
