使用yarn 2工作区在monorepo中的两个项目之间共享打字稿代码

我想在打字稿中建立一个包含客户端部分（react-app）、服务器部分（express）和共享库（utils）的项目。我使用yarn 2工作区并希望避免使用larna（如果可能的话）。不幸的是，几天以来我一直无法让它工作（并且进行了大量的谷歌搜索......）。当尝试运行客户端应用程序时，我收到错误：

找不到模块“utils”或其相应的类型声明。 TS2307

有人知道我做错了什么吗？

这是我的项目结构：

• .yarn
• packages
  • 客户端（使用 create-react-app 创建）
  • utils（使用yarn tsc --init 创建）
  • server
• .pnp.js
• .yarnrc.yml
• 包.json
• 纱线锁

package.json（根）：

{
  "private": true,
  "name": "monorepo with shared library and yarn 2 workspaces",
  "workspaces": [
    "packages/*"
  ],
  "scripts": {
    "client": "yarn workspace client start",
    "server": "yarn workspace server start",
    "prepare": "yarn workspace utils build"
  }
}

utils/package.json：

{
    "name": "utils",

    "main": "dist/index.js",
    "types": "dist/index.d.ts",

    },
    "scripts": {
        "build": "tsc -b --verbose"
    }
}

utils/src/index.ts：

function test() {
    console.log("this is a function from the shared library ");
}

export = {
    test
}

客户端/package.json

{
  "name": "client",

  "dependencies": {

    "web-vitals": "^0.2.4"
  },
  "scripts": {
    "start": "react-scripts start --verbose",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"

  "eslintConfig": {
    "extends": [
      "react-app",
      "react-app/jest"
    ]
  },
  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  },
  "devDependencies": {
    "eslint-config-react-app": "^6.0.0"
  }
}

我在 client/src/App.tsx 中添加了一个简单的导入用于测试：

import React from "react";
import logo from "./logo.svg";
import "./App.css";
import shared from "utils";

...

谢谢你！

我成功了。 “纱线工作区客户端添加实用程序”成功了。
