Question

我无法在 android 模拟器或 android 手机上运行 flutter 应用程序。我在 m1 mac 上安装了最近发布的适用于 arm-mac 平台的 android studio。如果我在这里做错了什么，或者是发布本身的问题，请回答。

调试控制台输出：

Answer 1

2023年。

转到应用程序 -> 右键单击​​ Android Studio -> 选择“显示包内容”。

我只有文件夹 .jbr （没有 .jre）。因此，我创建名为 .jre 的新文件夹，并复制文件夹“Contents”（来自 .jbr）-> 粘贴到 .jre 文件夹。

打开终端并运行：flutter doctor -v

这对我行得通。

Answer 2

转到应用程序然后右键单击 Android Studio，然后选择显示包内容，在其中创建一个jre名为的新文件夹jdk并将其内容复制jre到jdk

Answer 3

我遇到这个问题是因为我没有安装Java。如果您在“系统偏好设置”下看不到 Java 图标，则表明未安装 Java 7 或更高版本。链接到 java.com
