使用create-react-app创建了React应用程序，如何在其中使用Decorator?

Question

1、问题描述

使用create-react-app创建了React应用程序，并执行npm run reject暴露出了相关Webpack配置。然后在代码中使用Decorator，编译失败了。报错信息如下：

2、环境描述（部分）

"react": "~16.4.1",
"react": "~16.4.1",
"react-dev-utils": "~5.0.1",
"react-dom": "~16.4.1",
"react-router-dom": "~4.3.1",
"babel-core": "6.26.0",
"babel-eslint": "7.2.3",
"babel-jest": "20.0.3",
"babel-loader": "7.1.2",
"babel-plugin-import": "~1.11.0",
"babel-plugin-transform-decorators-legacy": "^1.3.5",
"babel-preset-react-app": "~3.1.1",
"babel-runtime": "6.26.0",

3、项目Decorator类代码

class Testable {
    constructor(target) {
        this.isTestable = target;
    }

    method() {
        console.log("Testable类");
    }
}

@Testable
class MyTestableClass {
    constructor() {
    }

    method() {
        console.log("MyTestableClass装饰类");
    }
}

/* 装饰类测试*/
let myTestableIns = new MyTestableClass();
console.log(myTestableIns.method());
