Question

我在构建应用程序时遇到问题（旧版本正在运行，但是我所有的新项目都收到此消息）我已经尝试过重启电脑并重新安装flutter，但这不会改变错误，而且我在任何地方都找不到解决方案

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

此项目\ CalendarProject是一个旧项目，但是我尝试构建的每个项目都收到此消息，指向D：\ projects \ CalendarProject

我的扑打医生似乎也很好

我认为这是android文件夹中的一个配置，会产生此错误，但无法想象会是什么

Answer 1

您在Android Studio中使用Flutter吗？如果是这样，请尝试在“ vs代码”中打开项目，android studio中的抖动似乎有问题...

Answer 2

已解决：

我用来创建项目的文件夹位于名为“ D：\ projects \ CalendarProject（V3）”的文件夹内（例如：D：\ projects \ CalendarProject（V3）\ flutter_app），不知道这是一个android sdk还是flutter漏洞，但是其中一个人显然认为CalendarProject（V3）是一个函数，并试图运行它。这解释了消息

'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

尝试构建Flutter项目时出错
