Android Studio 3.0 rc2：Android 设备监视器无法打开

Question

我最近使用应用程序内更新部分的 Beta 通道将我的 Android Studio 更新到 3.0 rc2。

今天我想使用 Android 设备监视器，其中发生异常并保存到 sdk 文件夹中的日志。

日志是这样的：

我不知道如何处理这个错误，我需要一种解决方法。我很乐意提出解决问题的任何建议，而无需提及 "download stable version" 和降级。

更新： 在我尝试通过更新部分的稳定通道更新到稳定版本后，我收到一些文件丢失的错误

gradle/m2repository/com/android/java/
gradle/m2repository/com/android/java/tools/
gradle/m2repository/com/android/java/tools/build/
gradle/m2repository/com/android/java/tools/build/java-lib-model-builder/
gradle/m2repository/com/android/java/tools/build/java-lib-model/

我正在尝试更新每个模块，也许我可以解决这个问题

UPDATE-2: 取消之前的错误并运行启用 Android Studio 后，似乎已更新但错误仍然存在，这是更新到稳定版本后的错误：

UPDATE-3: 经过大量搜索，我找到了解决方案，但这不是答案，所以我将此更新添加到问题中。

我可以通过 cmd 或 powershell 转到 /sdk/tools/ 和运行 monitor.bat 文件来手动运行 Android 设备监视器，现在我有访问此功能，但即使是现在，Android Studio 也无法为我打开它！！！！请如果有人可以帮助我 post 一个答案告诉我这个问题的解决方法。

Answer 1

如果您在 windows 上，请尝试在管理模式下打开您的 Android Studio（运行作为管理员）

Answer 2

经过多次尝试和捕捉！我终于解决了这个问题。 Android Studio 3.0 不完全支持 JDK 9 在我的系统上安装 JDK 8 并将其设置为 JAVA_HOME 变量并重新启动系统后，现在一切正常。我得到它是因为我想安装 Nativescript 但我不能因为它只支持 JDK 8。这是我的第一个线索

设置JAVA_HOME变量到JDK8目录就可以了
