任何人都可以用 android 工具链和 android 工作室解决 flutter 医生问题的这些问题吗？

Question

谁能帮我解决设置 Flutter 的问题。

我有几个错误，特别是两个类别的问题。

第一期

[!] Android toolchain - 我遇到了一个（看似常见的）未知许可证状态问题。 但是，常见的修复并没有奏效，例如flutter doctor --android-licenses ，可以在下面的控制台 output 中看到。

第 2 期

[!] Android studio - The second problem is the location of android studio is not working, I was getting [!] Android Studio (not installed) , so then I tried using flutter config --android-studio-dir=C:\Program Files\Android\Android Studio\ 。 现在我遇到了两个问题：

[!] Android Studio
    X android-studio-dir = C:\Program
    X Android Studio not found at C:\Program

这在下面也可见。

这是简化的控制台 output，仅显示问题：

C:\Users\anonymous\OneDrive\Documents\Frameworks\flutter>flutter doctor

Answer 1

问题 2 的解决方案是您对命令flutter config --android-studio-dir=C:\Program Files\Android\Android Studio\执行了错误的语法

它应该是flutter config --android-studio-dir="C:\Program Files\Android\Android Studio"

您缺少文件路径周围的引号。
