尝试构建颤振项目时出错

Question

我在构建应用程序时遇到问题（旧应用程序正在运行，但我的所有新项目都收到此消息） 我已经尝试重新启动我的电脑并重新安装颤振，但这并没有改变错误，我无法在任何地方找到解决方案

Launching lib\main.dart on Android SDK built for x86 in debug mode...
Running Gradle task 'assembleDebug'...
'D:\projects\CalendarProject' is not recognized as an internal or external command,
operable program or batch file.
Exception: Gradle task assembleDebug failed with exit code 1

这个项目\CalendarProject 是一个旧项目，但我尝试构建的每个项目都会收到指向 D:\projects\CalendarProject 的消息

我的颤振医生看起来也很好

我认为是 android 文件夹中的一个配置产生了这个错误，但无法想象它会是什么

Answer 1

你在 android studio 中使用颤振吗？如果是这样，请尝试在“vs code”中打开项目，android studio中的flutter似乎有问题......

Answer 2

已解决：

我用来创建项目的文件夹位于名为“D:\projects\CalendarProject(V3)”的文件夹中（例如：D:\projects\CalendarProject(V3)\flutter_app） ，不知道这是一个 android sdk 还是颤振错误，但显然其中一个认为 CalendarProject(V3) 是一个函数并试图运行它。这解释了信息

'D:\projects\CalendarProject' is not recognized as an internal or external command,
operable program or batch file.

通过更改目录修复

您可以使用以下方法重新创建错误：

>>mkdir teste(v3)
>>cd "teste(v3)"
>>flutter create app
>>cd app
>>flutter build apk
