我正在使用 TypeScript 编写 React 应用程序。我为我的组件使用 material-ui。我正在为 material-ui 的 Button 组件编写自定义包装器。它看起来像这样：

import MUIButton, { ButtonProps } from "@material-ui/core/Button";
import withStyles, { WithStyles } from "@material-ui/core/styles/withStyles";
import classNames from "classnames";
import React, { PureComponent } from "react";
import styles from "./styles";

export interface OwnProps {
  color: "primary" | "danger" | "warning" | "transparent";
  size: "sm" | "lg";
}

export interface Props
  extends WithStyles<typeof styles>,
    OwnProps,
    ButtonProps {}

export class Button extends PureComponent<Props> {
  render() {
    const { color, size, classes, children, ...rest } = this.props;
    const btnClasses = classNames({
      [classes.button]: true,
      [classes[size]]: size,
      [classes[color]]: color
    });
    return (
      <MUIButton {...rest} className={btnClasses}>
        {children}
      </MUIButton>
    );
  }
}

export default withStyles(styles)(Button);

问题是这里Props的定义抛出了错误信息：

Named property 'color' of types 'OwnProps' and 'ButtonProps' are not identical.
[ts]
Interface 'Props' cannot simultaneously extend types 'OwnProps' and 'ButtonProps'.
  Named property 'size' of types 'OwnProps' and 'ButtonProps' are not identical.
Named property 'color' of types 'OwnProps' and 'ButtonProps' are not identical.
[ts]
Interface 'Props' cannot simultaneously extend types 'OwnProps' and 'ButtonProps'.
  Named property 'size' of types 'OwnProps' and 'ButtonProps' are not identical.

如果我改为写，这个错误就会消失：

export class Button extends PureComponent<Props & ButtonProps> {

但是当使用 Button 时，props颜色和大小会抛出错误：

The expected type comes from property 'color' which is declared here on type 'IntrinsicAttributes & Pick<Props & ButtonProps, ...

我如何正确地告诉组件它有我定义的props ( OwnProps) 以及像往常一样来自 Button 的props？
