flutter - 哎呀；颤振意外退出：“无效参数

问题描述

当我单击 Pub 进入 pubspec.yaml 时，弹出错误：

Oops; flutter has exited unexpectedly: "Invalid argument(s): Cannot find executable for C:\Users\Ali\flutter\bin\cache\dart-sdk\bin\pub.bat.".
A crash report has been written to C:\Users\Ali\AndroidStudioProjects\inheritance_widgeta_context\flutter_17.log.

我已更新所有 SDK 工具

如何解决这个问题？

这是日志：

Flutter 崩溃报告。请在https://github.com/flutter/flutter/issues报告错误。

命令

flutter --no-color pub get

例外

解决方案

我通过以下3个步骤解决了这个问题，

1-:- 你需要禁用你的病毒防护，

2-:- 你应该完全删除缓存文件夹（它位于 ex:- 'C:\flutter\bin\cache'）

3-：运行“Flutter Doctor”，它将再次下载所有工件
