预期有0个参数，但有1个

Question

我需要一些有关在我的react应用中实现redux的帮助。打字稿未能编译，并出现以下错误：

/ Users / XXXXXXX / SignIn / index.tsx（12,71）中的TypeScript错误：预期为0参数，但得到1。[TS2554

这是我的index.tsx文件：

import SignIn from "./SignIn";
//@ts-ignore
import { connect } from "react-redux";
import { compose } from "redux";
import { withRouter } from "react-router-dom";
import { signIn } from "../../ducks/user";

const mapDispatchToProps = (dispatch: any) => ({
  signIn: (form: any) => dispatch(signIn(form))
});

export default compose(withRouter, connect(null, mapDispatchToProps))(SignIn);

谢谢你们的帮助

Answer 1

export default compose(withRouter, connect(null, mapDispatchToProps))(SignIn);

将已包装的SignIn组件与connect HOC一起移入，因为它是用redux装饰的。

export default compose(withRouter, connect(null, mapDispatchToProps)(SignIn));
