反应:检查器不是一个函数 [英] React: checker is not a function

问题描述

我在我的 React 应用程序的控制台中收到这条奇怪的警告消息.

I'm getting this weird warning message in the console for my React app.

Warning: Failed propType: checker is not a function 检查Chart的render方法.

Warning: Failed propType: checker is not a function Check the render method of Chart.

我根本没有任何检查方法.如果我删除我的 propTypes，警告就会消失.有什么想法吗?

I do not have any checker method at all. If I remove my propTypes, the warning is gone. Any ideas?

我的反应组件:

var Chart = React.createClass({
  //...
  propTypes: {
    legend: React.PropTypes.bool,
    max: React.PropTypes.number,
    min: React.PropTypes.number,
    series: React.PropTypes.arrayOf(
      React.PropTypes.shape({
        label: React.PropTypes.string,
        values: React.PropTypes.arrayOf(
          React.PropTypes.arrayOf(
            React.PropTypes.oneOfType(
              React.PropTypes.number,
              React.PropTypes.object // Date
            )
          )
        ),
        colorIndex: React.PropTypes.string
      })
    ).isRequired,
    threshold: React.PropTypes.number,
    type: React.PropTypes.oneOf(['line', 'bar', 'area']),
    units: React.PropTypes.string,
    xAxis: React.PropTypes.arrayOf(React.PropTypes.string)
  },
  render: function() {
    return (<svg>...</svg>);
  }
  //...
});

我发送到 Chart 组件的有效载荷是这个:

The payload I send to the Chart component is this one:

var series = [
  {label: 'first', values: [[5,2], [4,3], [3,3], [2,2], [1,1]], colorIndex: "graph-1"},
  {label: 'second', values: [[5,3], [4,2], [3,0], [2,0], [1,0]], colorIndex: "graph-2"}
];

推荐答案

已将拉取请求合并到 React 存储库，以便在再次发生此类错误时为开发人员提供更好的反馈.

A pull request has been merged to the React repo that provides a better feedback for the developer whenever a mistake like this happens again.

现在，验证消息将如下所示:

Now, the validation message will look like the following:

提供给 oneOf 的参数无效，需要一个数组实例.

Invalid argument supplied to oneOf, expected an instance of array.

这应该是 React 0.14 的一部分.

This should be part of React 0.14.
