我开发Flutter应用已经有一段时间了。自从上次更新后，我收到了这条消息：
在Flutter SDK中找不到Dart。请在终端运行“Flutter医生”，然后重新加载项目，一旦所有问题得到解决。
我现在无法在vs代码中运行我的应用程序。当我在终端中运行flutter doctor时，一切似乎都很好。

这是我的日志。

我该如何解决这个问题？

解决方案对我起作用了。
转到你的flutter sdk所在的目录。然后导航到C：/flutterSDKDir/bin/cache/dart-sdk/bin
复制url
创建新的系统变量路径并粘贴url。会成功的

我解决了这个问题，删除Flutter文件夹，并再次下载

inkz8wg93#

看起来你可能有两个Flutter SDK的副本：

C：\Users\yugiyuu\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\flutter
C：\src\flutter

VS Code选择了第一个（可能你在dart.flutterSdkPath中有这个设置？）我的猜测是，当你从终端运行“Flutter医生”时，你运行的是第二个。
如果您从终端运行“C：\Users\yugiyuu\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\flutter\bin\flutter.bat doctor”，它可能会下载Dart SDK并修复问题，但最好消除SDK的一个副本以避免混淆。

编辑：实际上，看起来你的Dart SDK可能不完整，因为dart.exe似乎已经找到，但文件夹正在被过滤掉-我怀疑是因为它没有analysis_server快照。尝试从Flutter SDK中删除“bin/cache/dart-sdk”文件夹，然后运行“C：\Users\yugiyuu\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\flutter\bin\flutter.bat doctor”（如果您想使用另一个SDK，则删除该SDK副本）。

如果仍然不起作用，请在https://github.com/Dart-Code/Dart-Code上提出问题，我们可以解决它（也许可以改进报告）。

C：\src\flutter\bin在环境变量的路径（用户变量）中添加此类型的URL。

kqlmhetl5#

按照以下步骤操作。
1.转到flutter sdk所在的目录。
1.导航到C:\flutter_windows_3.10.1-stable\flutter\bin\cache\dart-sdk\bin。
1.复制路径C:\flutter_windows_3.10.1-stable\flutter\bin\cache\dart-sdk\bin并将其粘贴到环境变量的顶部。

在Flutter SDK中找不到Dart
