pub get 失败命令：“C:\src\flutter\bin\cache\dart-sdk\bin\dart __deprecated_pub --color --directory ..\..\src\flutter\ ........”退出代码：69

Question

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

#0      throwToolExit (package:flutter_tools/src/base/common.dart:10:3)
#1      _DefaultPub._runWithStdioInherited (package:flutter_tools/src/dart/pub.dart:468:7)

#2      _DefaultPub.get (package:flutter_tools/src/dart/pub.dart:346:5)

<asynchronous suspension>
#4      Cache.updateAll (package:flutter_tools/src/cache.dart:677:9)

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

Answer 1

我遇到了同样的问题，我通过运行flutter clean,解决了它flutter pub upgrade，然后flutter pub get

Answer 2

我通过 Chat GPT 找到了解决方案。

只需禁用所有防病毒程序，我想之后我可以禁用 flutter SDK 的保护。

顺便说一下，现在一星期不能使用 flutter 已经很满意了
