未定义“属性” [英] 'Proptypes' is not defined

问题描述

我将在以下帮助下设置新的React： https://github.com / facebookincubator / create-react-app

I'm setting up a new React with the help of: https://github.com/facebookincubator/create-react-app

但是，我遇到了皮毛问题。我收到以下提示错误 PropTypes未定义。 （no-undef）。

However, I'm running into a linting issue. I'm receiving the following linting error 'PropTypes' is not defined. (no-undef).

以下是引起问题的代码：

Here is the code that is causing the issue:

import React, { Component } from 'react';
import PropTypes from 'prop-types';

class Routers extends Component {
  static propTypes = {
    history: PropTypes.object.isRequired
  };

...

我尝试使用 react / prop-types 规则，但是没用。

I tried playing around with the react/prop-types rule, but to no avail.

推荐答案

根据此问题评论。

这似乎是因为您安装了 eslint 4.x 时，您只应使用 create-react-app 。您应该删除所有手动安装的eslint，然后使用存储库随附的那个。

It appears to be because you have installed eslint 4.x when you should just use the eslint version that is shipped with create-react-app. You should remove any eslint you have manually installed and use the one that comes with the repo.
