android - React Native WebStorm Emulator 无法启动 - 错误无法启动模拟器。原因 : No emulators found as an output of `emulator -list-avds`

Question

我是 WebStorm 和 React Native 的新手，在设置我的环境时遇到了一个错误，与我看到的其他帖子相比，我的环境显得独特。

客观的

我在 WebStorm 中设置了一个默认项目，我的目标是在 Android 模拟器上运行该项目，我使用的是 Windows PC。

我试过的

我在 WebStorm 中设置了一个简单的调试配置



我还通过 Android Studio 下载了一个 Android 模拟器，并在我的计算机上运行它。



现在，当我为我的调试模拟器单击运行时，我收到以下错误:

adb不在您的 %PATH% 上;确保添加 adb.exe 所在的文件夹位于(通常是 $ANDROID_HOME/platform-tools ，其中 $ANDROID_HOME 是您的 Android SDK 安装目录，通常是 C:\Users\Your.Name\AppData\Local\Android\sdk ，您可以在 Windows cmd 控制台中运行 where adb 命令来找到它)到 %PATH%在 下系统环境变量然后重新启动 WebStorm。

您还需要定义 %ANDROID_SDK_ROOT%错误消息中每个建议的环境变量
