【问题描述】：

我尝试删除项目的颤振包并使用以下命令进行更新 但找不到解决方案，为什么这个包在“\Pub\Cache\hosted\pub.dartlang.org\firebase_admob-0.9.3+2”文件夹中找到文件“pubspec.yaml”。这是错误。谁能告诉我如何从我项目的 pubspec.yaml" 文件中更新包

PS D:\flutter\delimeals> flutter packages get
Waiting for another flutter command to release the startup lock...
Could not find a file named "pubspec.yaml" in "C:\Users\omkar\AppData\Roaming\Pub\Cache\hosted\pub.dartlang.org\firebase_admob-0.9.3+2".
Running "flutter pub get" in delimeals...
pub get failed (66; Could not find a file named "pubspec.yaml" in
"C:\Users\omkar\AppData\Roaming\Pub\Cache\hosted\pub.dartlang.org\firebase_admob-0.9.3+2".)

我在删除 pub 文件夹后收到此错误，因为我想删除不需要的包。
