javascript - Eslint 未检测到 React 组件的定义属性类型

使用以下代码创建了一个 javascript 文件:

import React, {Component, Fragment} from "react"
import PropTypes from "prop-types"

export default class DefaultBootstrap extends Component {
render() { return (<div>Hi</div>) }
}

DefaultBootstrap.propTypes = {
name: PropTypes.bool.isRequired
}

当我运行 npm start 时,它显示以下 linter 错误:

xxx/xxx/index.js
1:1 warning Definition for rule 'prop-types' was not found prop-types

所以我的问题是,为什么即使我已经在上面定义了 prop-types 规则,它仍然向我显示上述警告?

我使用 Webpack、Babel、React 和 Eslinter 来设置我的应用程序。

.eslintrc.json

{
"parser": "babel-eslint",
"plugins": ["react"],
"rules": {
"prop-types": ["warn"],
}
}

}
}

webpack.config.js (Click here To See Complete File)

    rules: [
{
test: /\.m?js$/,
exclude: /(node_modules|bower_components)/,
use: {
loader: 'babel-loader',
options: {
presets: ['@babel/preset-env']
}
}
},
{
test: /\.js$/,
exclude: /node_modules/,
use: ['babel-loader', 'eslint-loader']
},

最佳答案

在查看您的代码之前,ESLint 首先寻找 prop-types 规则的实现。错误消息说它找不到该规则。由于 prop-types 规则是由插件 eslint-plugin-react 提供的,并且不是内置规则之一,因此您需要在其前面加上前缀在你的 .eslintrc.json 中使用插件名称和斜杠命名:react/prop-types。这告诉 ESLint 它应该在 eslint-plugin-react 中寻找 prop-types 规则。

{
"parser": "babel-eslint",
"plugins": ["react"],
"rules": {
"react/prop-types": ["warn"],
}
}

您可以在 rule configuration docs 中阅读更多内容.
