flowise local server setup error

I am trying to install local server for Flowise but running into the following issue:

C:\flowise\Flowise-main\Flowise-main>yarn install
yarn install v1.22.22
info No lockfile found.
[1/5] Validating package.json...
error flowise@3.0.11: The engine "node" is incompatible with this module. Expected version ">=18.15.0 <19.0.0 || ^20". Got "24.11.1"
warning flowise@3.0.11: The engine "pnpm" appears to be invalid.
error Found incompatible module.
info Visit https://yarnpkg.com/en/docs/cli/install for documentation about this command.

Please help!

先从 yarn install 的输出和项目的 package.json 入手，重点关注声明的 Node.js 引擎范围和报告的 Node.js 版本。检查安装说明或设置入口是否处理了这一不匹配，然后验证使用受支持的版本能否成功完成文档中说明的设置。
