babel-loader@7.1.2需要webpack @ 2的同位体|| 3，但未安装

Question

安装所有node_modules时遇到此问题。这让我发疯。

babel-loader@7.1.2需要webpack @ 2的同位体|| 3，但未安装。

这是我的package.json文件

    "build": "react-scripts build",
    "test": "react-scripts test --env=jsdom",
    "eject": "react-scripts eject"
  }
}

我正在create-react-app为此项目使用。因此，我无法更改webpack.config.js文件。我应该在这里做什么？

请阅读这篇文章。它描述了对等依赖性。

这意味着您根本没有安装webpack或安装了其他版本（webpack 1.x）。但是此插件需要版本2或3中的webpack才能正常运行。

你能做的是

npm install webpack -g

因此，npm将在您的系统上安装最新版本的webpack。但是现在，当其他加载器需要较旧版本的Webpack时，可能会出现其他对等警告。
