[英]Why do I keep getting "JSX is not defined no-undef"
在我的主頁上添加輪播時,我遇到了一個問題。 我收到錯誤:
“JSX”未定義。
我一直在查看 Stack Overflow、GitHub 以及 Google,它們都給出了相對接近的答案,但我不確定我可能做錯了什么。
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;
我的幻燈片結構完全相同:
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;
至於我的.eslintrc.json

我已經嘗試過以下列出的內容: Stack Overflow answer 我也嘗試過這個: Official answer
所以,對我有用的答案是改變我的.eslintrc.json
{
...
"globals": {
"JSX": "readonly"
}
}
在 ESLint 文檔中:
ESLint 的一些核心規則依賴於對代碼在運行時可用的全局變量的了解。 由於這些在不同環境之間可能會有很大差異,並且會在運行時進行修改,因此 ESLint 不會假設您的執行環境中存在哪些全局變量。
對於我的項目,一旦定義了這個全局變量,它將默認為node_modules/@types/react
中的JSX
命名空間
在您的Carousel.tsx中,使用如下內容更新您的界面:
interface IProps { children: React.ReactNode }
