为什么我不断收到“JSX 未定义 no-undef”

Question

在我的主页上添加轮播时，我遇到了一个问题。 我收到错误：

“JSX”未定义。

我一直在查看 Stack Overflow、GitHub 以及 Google，它们都给出了相对接近的答案，但我不确定我可能做错了什么。

我的carousel.tsx文件如下

import * as React from "react";
import styled from "styled-components";

const SCarouselWrapper = styled.div`
  display: flex;
`;

interface IProps {
  children: JSX.Element[];
}

const Carousel = ({ children }: IProps) => {
  const activeSlide = children.map(slide => (
    <>
      {slide}
    </>
  ));

  return (
    <div>
      <SCarouselWrapper>
        {activeSlide}
      </SCarouselWrapper>
    </div>
  );
};

export default Carousel;

我的幻灯片结构完全相同：

import * as React from "react";
import styled from "styled-components";

const SContainer = styled.div`
  align-items: center;
  display: flex;
`;

const SlideOne = () => (
  <SContainer>
    <img src="../../../../../content/images/logo.jpg" />
  </SContainer>
);

export default SlideOne;

至于我的.eslintrc.json ：

我已经尝试过以下列出的内容： Stack Overflow answer 我也尝试过这个： Official answer

Answer 1

所以，对我有用的答案是改变我的.eslintrc.json

{ 
  ... 
  "globals": {
     "JSX": "readonly"
  }
}

在 ESLint 文档中：

ESLint 的一些核心规则依赖于对代码在运行时可用的全局变量的了解。 由于这些在不同环境之间可能会有很大差异，并且会在运行时进行修改，因此 ESLint 不会假设您的执行环境中存在哪些全局变量。

对于我的项目，一旦定义了这个全局变量，它将默认为node_modules/@types/react中的JSX命名空间

Answer 2

在您的Carousel.tsx中，使用如下内容更新您的界面：

 interface IProps { children: React.ReactNode }
