我正在尝试实现一个基本的 ThemeProvider与 StyledComponents。我已经毫无问题地基本使用了 styled-components，但是，在尝试实现 <ThemeProvider /> 的使用时它不赞成我正在尝试做的事情。该应用程序是用 gatsby 和 Typescript 构建的(对此仍然是新的)

我尝试调试了一下，包括“扩展”基础的建议 styled-components包括您的主题，例如 as this gist . 错误消息对我来说有点难以追查:

Type '{ children: Element[]; theme: DefaultTheme; }' is not assignable to type 'Readonly>'. Types of property 'children' are incompatible. Type 'Element[]' is not assignable to type 'string | number | ReactElement ReactElement Component)> | null) | (new (props: any) => Component)> | undefined'. Type 'Element[]' is not assignable to type 'string'.ts(2322)

// index.tsx

import { ThemeProvider } from "styled-components";
import { theme } from "./theme";

export default () => {
  return (
    <ThemeProvider theme={theme}>
      <Global />
      <Comp1 />
      <Comp2 />
      <Comp3 />
    </ThemeProvider>
  );
}

即使是 ThemeProvider 的最基本配置也只是包装一个 div 错误:

打字:

//styled.d.ts
import "styled-components";

declare module "styled-components" {
  export interface DefaultTheme {
    colors: {
      purple1: string;
      yellow1: string;
      blue1: string;
    };
  }
}

和我的主题:

import { DefaultTheme } from "styled-components";

export const theme: DefaultTheme = {
  colors: {
    purple1: "#9b91f2",
    yellow1: "#f2f0d5",
    blue1: "#1c4d8c"
  }
};

和 package-json:

"dependencies": {
    "babel-plugin-styled-components": "^1.10.6",
    "gatsby": "^2.17.4",
    "gatsby-plugin-styled-components": "^3.1.11",
    "react": "^16.11.0",
    "react-dom": "^16.11.0",
    "styled-components": "^4.4.0"
  },
  "devDependencies": {
    "@types/styled-components": "^4.1.19",
    "gatsby-plugin-tslint": "0.0.2",
    "gatsby-plugin-typescript": "^2.1.15",
    "tslint": "^5.20.0",
    "tslint-loader": "^3.5.4",
    "tslint-react": "^4.1.0",
    "typescript": "^3.6.4"
  }

最佳答案

当我使用 @0.8.0 版本的 chakra-ui/core 库时，同样的事情发生在我身上。

后来升级了release candidate版本修复了不兼容的问题。
