Question

我的组件代码如下所示。

    import React, { Component, PropTypes } from 'react';

export default class HeroBanner extends Component {
  constructor(props) {
    super(props);
  }

  render() {
    const { columns, content } = this.props.data;

    return (
      <div className="conatainer-class">

      </div>
    );
  }
}

HeroBanner.propTypes = {
  content: PropTypes.object,
  columns: PropTypes.string,
};

我的.babelrc文件是：

{
 "presets": ["react", "es2015","stage-0"],
 "plugins": ["transform-es2015-modules-amd"]
}

当发生转化时，它将输出作为＆＃34;对象＆＃34;而不是函数或字符串。

这是输出对象。横幅：横幅（道具） esModule：是的 __proto ：对象

这导致React抛出错误：

未捕获的不变违规：元素类型无效：期望一个字符串（对于内置组件）或一个类/函数（对于复合组件）但得到：object。

透明代码：

ES6模块中的内容，然后在ES5模块中，您需要通过Workbook A (source: Table with data)访问它：

Workbook B (Pivot Table -Connected to Table in Workbook A)

或类似，在RequireJS中，

Hello world!
Hello WORLD!!!!!
