React Native WebStorm Emulator 无法启动 - 错误无法启动模拟器。原因：没有找到模拟器作为 `emulator -list-avds` 的输出

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，与我见过的另一篇文章相比，这个错误看起来很独特。

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，当我单击调试模拟器的运行时，出现以下错误：

其他信息

这是我的路径系统变量的图片：

Answer 1

adb不在你的身上%PATH%；确保添加这些文件夹adb.exe的位置（通常$ANDROID_HOME/platform-tools，这里$ANDROID_HOME是你的Android SDK安装目录，通常C:\Users\Your.Name\AppData\Local\Android\sdk，你可以运行where adb命令在Windows控制台在cmd找到它），以%PATH%在系统环境变量，然后重新启动WebStorm。

您还需要%ANDROID_SDK_ROOT%根据错误消息中的建议定义环境变量
