【问题描述】：

我正在尝试运行 yarn start 并收到以下错误：

????  /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"
    }
  }
}

发生了什么事？我假设我使用了其中一个软件包的错误版本？我现在已经卸载并重新安装了几次软件包，但似乎没有什么不同。

标签： javascript yarnpkg

【解决方案1】：

我通过npm下载了core-js@3.6.5，看了下路径：

核心-js/模块

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

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'。
