上次当我尝试创建一个新的 flutter 项目时，我出现了这个问题

The semaphore timeout period has expired.
pub get failed
command: "C:\src\flutter\bin\cache\dart-sdk\bin\dart __deprecated_pub --directory packages\flutter_tools get --example"
pub env: {
  "FLUTTER_ROOT": "C:\src\flutter",
  "PUB_ENVIRONMENT": "flutter_cli:get",
  "PUB_CACHE": "C:\Users\ahmed\AppData\Local\Pub\Cache",
}
exit code: 69

我尝试通过从 flutter-sdk 中删除 cash 并flutter pub cache repair在 cmd 上运行来修复它，但它不起作用，然后我删除了 dart 和 flutter sdk 并再次下载它们，并将它们的路径放入系统环境中并输入flutter doctor，但这个错误仍然出现在我身上
