ReScript、TypeScript：找不到模块“@rescript/react/src/ReactDOM.gen”或其相应的类型声明

Question

我正在逐步将 React to TypeScript 的应用程序重写为 ReScript。我已经在 ReScript 中实现了几个组件，但这是第一个，我将 ReactDOM.Style.t 用作我的组件的属性。

这是我最小化的组件代码：

@genType
@react.component
let make = (~sx: option<ReactDOM.Style.t>=?) => {
  <div></div>
}

ReScript 编译正常（除了没有使用 sx 的警告，但我们可以忽略它）。

我生成了以下 bs.js，似乎没问题：

// Generated by ReScript, PLEASE EDIT WITH CARE

import * as React from "react";

function InhypedIcon(Props) {
  return React.createElement("div", undefined);
}

var make = InhypedIcon;

export {
  make ,

}
/* react Not a pure module */

和下面对应的.gen.tsx文件，导致问题：

/* TypeScript file generated from InhypedIcon.res by genType. */
/* eslint-disable import/first */


import * as React from 'react';

// @ts-ignore: Implicit any on import
import * as InhypedIconBS__Es6Import from './InhypedIcon.bs';
const InhypedIconBS: any = InhypedIconBS__Es6Import;

import type {Style_t as ReactDOM_Style_t} from '@rescript/react/src/ReactDOM.gen';

// tslint:disable-next-line:interface-over-type-literal
export type Props = { readonly sx?: ReactDOM_Style_t };

export const make: React.ComponentType<{ readonly sx?: ReactDOM_Style_t }> = InhypedIconBS.make;

编译失败，出现 TypeScript 错误：

TypeScript error in /app/src/icons/InhypedIcon.gen.tsx(11,48):
Cannot find module '@rescript/react/src/ReactDOM.gen' or its corresponding type declarations.  TS2307

     9 | const InhypedIconBS: any = InhypedIconBS__Es6Import;
    10 |
  > 11 | import type {Style_t as ReactDOM_Style_t} from '@rescript/react/src/ReactDOM.gen';
       |                                                ^
    12 |
    13 | // tslint:disable-next-line:interface-over-type-literal
    14 | export type Props = { readonly sx?: ReactDOM_Style_t };

我明白了，那个TS找不到rescript/react/src/ReactDOM.gen，但是我真的不知道为什么。知道如何解决这个问题吗？

我的包版本：

node: v16.6.2

"typescript": "^4.1.2"
"rescript": "^9.1.4"
"@rescript/react": "^0.10.3"

谢谢。

这是因为 GenType 没有附带 react 绑定，所以如果你需要它，你必须自己输入 (cf the docs to import types):

@genType.import(("react", "CSSProperties"))
type reactStyle = ReactDOM.Style.t

@genType
@react.component
let make = (~sx: option<reactStyle>=?) => {
  <div></div>
}

这应该有效。
