yarn version
4.9.4
报错解决流程
1.set NODE_TLS_REJECT_UNAUTHORIZED=1
不生效
2. npm config set strict-ssl false
不生效，这说明 Yarn 的证书验证机制没有受到 npm 配置的影响，因为 Yarn 使用自己的配置系统和网络请求逻辑。npm config 对 Yarn 无效。

最终解决方案
在项目中设置 .yarnrc.yml 文件

增加

unsafe-http-whitelist: ["*"]

enableStrictSsl: false

yarn install 报错
Usage Error: Unrecognized or legacy configuration settings found: unsafe-http-whitelist - run “yarn config” to see the list of settings supported in Yarn (in D:\a_GenAI\agent_guanlan\gaia.yarnrc.yml)
使用命令 yarn config get
➤ YN0034: Invalid configuration key “unsafe-http-whitelist” in /D:/a_GenAI/agent_guanlan/gaia/.yarnrc.yml

删掉只写，问题解决

enableStrictSsl: false
