我已删除 Pub\Cache\hosted\pub.dartlang.org 文件夹来更新 flutter 包，但在 flutter 包中显示错误

Question

我尝试删除项目的 flutter 包并使用以下命令更新相同的包\n但无法找到解决方案，为什么此包获取在“\\Pub\\Cache\\hosted”中找到文件“pubspec.yaml” \\pub.dartlang.org\\firebase_admob-0.9.3+2”文件夹。这是错误。谁能告诉我如何从我的项目的 pubspec.yaml" 文件更新包

\n\n

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

当我删除 pub 文件夹以删除不需要的包时，我收到此错误。
