Android 颤振安装apk导致安装\u解析\u失败\u无\u证书

我一直在android emulator上开发和安装我的apk，并且在物理设备上没有任何问题

然后突然，我在安装时出错了。我能想到的唯一改变就是删除并重新生成了我的pubspec.lock

我用命令构建和安装

flutter build apk --debug
flutter instal apk

在物理设备上安装时，我得到

Package install error: Failure [INSTALL_PARSE_FAILED_NO_CERTIFICATES]
Install failed

在模拟器上安装时，我得到

adb: failed to install /home/user/src/MobileApp/build/app/outputs/flutter-apk/app.apk: Failure [INSTALL_PARSE_FAILED_NO_CERTIFICATES: Package
/data/app/vmdl770003105.tmp/base.apk has no certificates at entry AndroidManifest.xml]
Install failed

我注意到，当我在~/.android文件夹中构建时，会创建一个debug.keystore.lock文件，但从未删除。我可以手动删除它，但每个后续生成过程都会创建此生成文件，而不会删除它
