无法在您的Flutter SDK中找到Dart

Question

我已经开发了一段时间的Flutter应用程序。自从最后一次更新以来，我一直收到这个消息：

在您的Flutter SDK中找不到Dart。请在终端中运行“flutter doctor”，然后在解决所有问题后重新加载项目。

我现在无法在VS Code中运行我的应用程序。当我在终端中运行flutter doctor时，一切似乎都很正常。

在终端中运行 dart --version 时，您的输出是什么？ - void

"'dart' 不是内部或外部命令，也不是可运行的程序或批处理文件。" - umut işgördü

你需要安装 Dart SDK。 - void

我发布了一个回答。看看吧。 - void

Answer 1

这个解决方案对我很有效。

前往存放Flutter SDK的目录，并导航至C:/flutterSDKDir/bin/cache/dart-sdk/bin。

复制URL。

创建新的系统变量路径并将URL粘贴到其中。它会起作用。

Answer 2

我解决了这个问题，通过删除flutter文件夹并重新下载它。

Answer 3

请按照以下步骤操作：

1. 进入您的Flutter SDK所在的目录。
2. 导航到 C:\flutter_windows_3.10.1-stable\flutter\bin\cache\dart-sdk\bin。
3. 将此路径 C:\flutter_windows_3.10.1-stable\flutter\bin\cache\dart-sdk\bin 复制并粘贴到环境变量的顶部。

Answer 4

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

Answer 5

看起来您可能有两个Flutter SDK的副本：

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

VS Code正在选择第一个（可能您已经在dart.flutterSdkPath中设置了它？）。 我猜当您从终端运行“flutter doctor”时，您正在运行第二个。

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，因为似乎已经找到了dart.exe，但是该文件夹被过滤掉了——我怀疑这是因为它没有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”（或者如果你想使用其他SDK，则删除该副本）。

如果仍然无法正常工作，请在https://github.com/Dart-Code/Dart-Code上提出问题，我们可以解决它（并可能改进报告）。
