要使用 Yarn 启动你提供的项目，可以按照以下步骤进行操作：
package.json

}

1. 安装 Yarn

首先，确保你已经安装了 Yarn。如果没有安装，可以通过以下命令安装：

使用 npm 安装 Yarn

npm install -g yarn

使用 Chocolatey 安装 Yarn（Windows 用户）

choco install yarn

使用 Homebrew 安装 Yarn（macOS 用户）

brew install yarn

2. 安装项目依赖

进入项目目录，然后使用 Yarn 安装项目依赖：

cd path/to/your/project
yarn install

3. 启动项目

项目依赖安装完成后，你可以使用以下命令启动项目：

开发模式启动

yarn serve

或者使用 dev 脚本：

yarn dev

生产模式启动

yarn serve:prod

4. 构建项目

如果你需要构建项目，可以使用以下命令：

开发模式构建

yarn build:dev

生产模式构建

yarn build:prod

5. 其他常用命令

• 运行单元测试：

  yarn test:unit
  

• 运行端到端测试：

  yarn test:e2e
  

• 启动 Mock 服务器：

  yarn mock
  

• 生成 SVG 图标组件：

  yarn svg
  

6. 部署到 OSS

如果你需要将构建结果部署到 OSS，可以使用以下命令：

部署开发环境构建结果

yarn build:dev-to-oss

部署生产环境构建结果

yarn build:prod-to-oss

7. 同时部署开发和生产环境

如果你想同时部署开发和生产环境的构建结果，可以使用以下命令：

yarn oss:all

8. 运行 ESLint 检查

yarn lint

总结

通过以上步骤，你可以使用 Yarn 成功启动和管理你的项目。Yarn 的命令与 package.json 中的脚本定义一致，因此你可以直接使用 yarn <script-name> 来运行对应的脚本。
