我目前正在将Typescript安装到一个存储库中,该存储库具有现有的Webpack和Babel设置,其中包括Styled Components。
由于Babel将负责编译,我已将tsc
配置为仅执行typechecking
。然而,使用一个定义样式化组件div的简单Typescript React组件,tsc
会给我以下错误:
core/ui/NoticeBanner/index.tsx:33:6 - error TS2786: 'BannerContainer' cannot be used as a JSX component.
Its return type 'ReactElement<Omit<Omit<Pick<DetailedHTMLProps<HTMLAttributes<HTMLDivElement>, HTMLDivElement>, "key" | keyof HTMLAttributes<...>> & { ...; }, never> & Partial<...>, "theme"> & { ...; }, string | JSXElementConstructor<...>>' is not a valid JSX element.

~~~~~~~~~~~~~~~
core/ui/NoticeBanner/index.tsx:41:8 - error TS2786: 'BannerText' cannot be used as a JSX component.

41 <BannerText>{message}</BannerText>
以下是有问题的组件:
import React from 'react';
import AlertWarning from 'material-ui/svg-icons/alert/warning';
import ActionInfo from 'material-ui/svg-icons/action/info';
import styled from 'styled-components';
const BannerContainer = styled.div`
background-color: rgba(243, 209, 121, 0.23);
padding: 10px 30px;
margin: 40px 0px;
flex-direction: row;
display: flex;
align-items: center;
`;
const BannerText = styled.div`
margin-left: 13px;
font-size: 18px;
font-weight: 400;
color: #333333 !important;
line-height: 140.28% !important;
`;
interface NoticeBannerProps {
message: string;
status: string;
}
const NoticeBanner = (props: NoticeBannerProps) => {
const { message, status } = props;
return (
<BannerContainer>
<div style={{ display: 'flex' }}>
{status === 'failed' ? (
<AlertWarning className="alert-icon" color="#dc3545" />
) : (
<ActionInfo className="info-icon" color="#8F2C87" />
)}
</div>
<BannerText>{message}</BannerText>
</BannerContainer>
);
};
export default NoticeBanner;
依赖版本

我在v5中尝试了不同版本的样式组件,以及不同版本的@types/react
和@types/styled-components
。
我有点纠结于我还可以研究什么,或者我可以用什么来调试问题。
我猜这要么是依赖关系图的问题(@types的版本没有正确对齐(。
我发现了这个问题。
我的存储库正在使用yarn工作区,有一个文件夹与它自己的node_modules
文件夹无关,导致了这个问题。将其添加到tsconfig.json
的exclude
配置选项中解决了此问题。
