错误消息非常明确 - 配置文件中的'output.path'没有设置。 –

我正在从[https://www.tutorialspoint.com/reactjs/reactjs_environment_setup.html]进行环境设置。我已经创建了与上述相同的文件夹结构，但是我正在获取上面的configuration.output.path错误 –

该链接不存在 - 您拼错了吗？无论采用哪种方式，您都应该将“webpack.config.js”添加到问题中，因为这绝对是问题所在。 –

随着错误消息指出：

configuration.output.path: The provided value "" is not an absolute path!

为什么多数民众赞成显示一个空字符串，而不是output.path实际价值，我不知道 - 但无论哪种方式，你的配置是错误的。 output.path的值具有为绝对路径，并且您将其设置为相对路径。

通常的方法周围的人这得到的是从节点导入path模块，并使用path.join，就像这样：

var path = require('path'); 

module.exports = { 
    /// ... 

    output: { 
     path: path.resolve(__dirname, "dist"), 
     filename: "index.js" 
    }, 

    // ... 
};

但是，因为你只是一味以输出文件的根目录中，你可以这样做：

// no path import needed 

module.exports = { 
    // ... 

    output: { 
     path: __dirname, 
     filename: "index.js" 
    }, 

    // ... 
};
