解决步骤 #

• 检查网络连通性：尝试访问https://registry.npmjs.org/@babel/helper-builder-react-jsx，或者ping 104.16.23.35，确认网络能正常连接npm官方源。如果无法访问，排查防火墙、路由器限制或网络运营商问题。
• 切换国内镜像源：执行以下命令将yarn registry替换为国内镜像，解决官方源访问不畅的问题：

  yarn config set registry https://registry.npmmirror.com
  

  之后重新运行yarn install。
• 清理代理配置：若之前设置过代理，可能代理失效导致连接失败。先查看当前代理设置：

  yarn config get proxy
  yarn config get https-proxy
  

  若存在无效代理，执行以下命令清空：

  yarn config delete proxy
  yarn config delete https-proxy
  

• 重置yarn配置：如果配置文件出现异常，执行重置命令恢复默认设置：

  yarn config reset
  

• 检查本地安全软件：临时关闭防火墙、杀毒软件等，确认是否是这类软件阻止了yarn的网络请求。
