[英]Type '{ children: Element; }' is not assignable to type 'IntrinsicAttributes & ReactNode'
[英]Typescript throws “is not assignable to type 'IntrinsicAttributes & { children?: ReactNode; }”
我知道这已被详细讨论过,但其他 SO 解决方案似乎不起作用,或者我无法实施它们。
我是 typescript 的新手,并且有以下内容:
import faker from "faker";
import React from "react";
import Index from "../components/Index";
import List from "../components/List";
interface Props {
departments: [
{
id: number;
name: string;
}
];
}
const IndexPage: React.FunctionComponent<Props> = ({ departments }) => {
return (
<>
<Index />
<List departments={departments} />
</>
);
};
export async function getStaticProps() {
let departments: { id: number; name: string }[] = [];
for (let i = 0; i < 50; i += 1) {
const name: string = await faker.company.companyName();
departments = [...departments, { id: i, name }];
}
return {
props: {
departments,
},
};
}
export default IndexPage;
虽然我不确定我是否正确实现了 TypeScript,但编译器会抛出此错误:
Type '{ departments: [{ id: number; name: string; }]; }' is not assignable to type 'IntrinsicAttributes & { children?: ReactNode; }'. Property 'departments' does not exist on type 'IntrinsicAttributes & { children?: ReactNode; }'.
编译器在<List>
组件上强调了部门属性。
为什么会引发此错误,我该如何解决?
Typescript 试图告诉您,您正试图将财产departments
提供给 object(在这种情况下,是一个 React 组件),它的类型没有该属性。
类型'IntrinsicAttributes & { children?: ReactNode; }'
'IntrinsicAttributes & { children?: ReactNode; }'
只是反应组件的默认类型; 如果departments
不包含在该类型的道具中(并且它不是),那么您不能将该道具传递给List
组件。
要解决此问题,您只需将departments
添加到List
的 props 的定义中
