【菜鳥搭建react項目之路4】【webpack】options has an unknown property 'contentBase'.

報錯信息：

[webpack-cli] Invalid options object. Dev Server has been initialized using an options object that does not match the API schema.
- options has an unknown property 'contentBase'. These properties are valid:

 

原因：

webpack配置代碼：

devServer: {
    contentBase: __dirname,
  },

其實信息提示得挺明白了，就是contentBase這個屬性不能用了。

 

解決方案：

因為contentBase已經棄用了，所以正確應該改為：

devServer: {
    // contentBase: __dirname,
    static: {
      directory: path.join(__dirname, "dist"),
    },
  },
