錯誤消息非常明確 - 配置文件中的'output.path'沒有設置。 –

我正在從[https://www.tutorialspoint.com/reactjs/reactjs_environment_setup.html]進行環境設置。我已經創建了與上述相同的文件夾結構，但是我正在獲取上面的configuration.output.path錯誤 –

該鏈接不存在 - 您拼錯了嗎？無論採用哪種方式，您都應該將「webpack.config.js」添加到問題中，因爲這絕對是問題所在。 –

隨着錯誤消息指出：

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

爲什麼多數民衆贊成顯示一個空字符串，而不是output.path實際價值，我不知道 - 但無論哪種方式，你的配置是錯誤的。 output.path的值具有爲絕對路徑，並且您將其設置爲相對路徑。

通常的方法周圍的人這得到的是從節點導入path模塊，並使用path.join，就像這樣：

var path = require('path'); 

module.exports = { 
    /// ... 

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

    // ... 
};

但是，因爲你只是一味以輸出文件的根目錄中，你可以這樣做：

// no path import needed 

module.exports = { 
    // ... 

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

    // ... 
};
