我有一个颤振项目，如果我执行命令“颤动运行”，它就会卡在运行 Gradle 任务“assembleDebug”上。它不会抛出错误消息或任何它什么都不做的事情。这只发生在我的台式电脑上。在我的笔记本电脑上一切正常。

下面我将向你展示我的颤振医生 -v 输出和颤振运行 -v 输出，但首先我会告诉你我已经做了什么。

我重新安装了颤振和android sdk。我想，项目文件以某种方式损坏了，所以我删除了整个项目并从我的 git 存储库中再次将其拉出。

我创建了一个新项目，其中包含来自 Flutter 的默认示例应用程序（您知道可以在其中按下按钮的那个，它会在屏幕中间告诉您按下它的次数。）起初是有效的，所以我想我在尝试将 moor_flutter 包集成到我的应用程序时搞砸了。（我知道那不是真的，因为如果我把它搞砸了，它也不会在我的笔记本电脑上工作，但我很绝望。）

无论如何，我一步一步地执行并在每次更改后运行应用程序，这样我就可以检查我是否犯了错误。

第 1 步：在 pubspec.yaml 中添加依赖项

第2步：添加设置数据库和测试表。

第3步：初始化数据库类

每次更改后，我都清理了颤振应用程序，生成了一个新的“xxx.g.dart”文件，这是使用 moor_flutter 包所必需的。一切正常。那天晚些时候，在我恢复动力后，我回到了我的电脑上，并试图再次启动我的测试应用程序以找出我做错了什么。我运行了我的测试应用程序，突然它不再通过“运行 Gradle 任务 'assembleDebug'...”了，我不明白为什么，因为我没有改变任何东西。

我查看了其他有同样问题的人的帖子，有人建议这是因为 linux 内核 5.5.5-arch1-1 以某种方式破坏了 gradlew，但我升级了我的笔记本电脑以检查这是否属实，但它仍然可以在我的笔记本电脑上运行。

因此，在我尝试在笔记本电脑上使用我的应用程序后，我自己想通了。周日晚上，我可以将应用程序从笔记本电脑推送到智能手机，但昨天在学校我什么也做不了。所以我想它一定是我的操作系统。我将我的 linux 内核更改为 lts 版本，现在一切正常。

andoid studio->tools->flutter->在studio中打开andoid模块

尝试在打开 android 模块后运行。对我来说，在我收到终端错误之后。
