Android React Native WebStorm Emulator无法启动-启动Emulator时出错。原因：未找到作为“emulator-list AVD”输出的仿真器`

我是WebStorm新手，React Native，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，这个错误显得很独特

客观的 我在WebStorm中设置了一个默认项目，我的目标是在Android仿真器上运行该项目，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，并在我的电脑上运行

现在，当我单击调试仿真器的run时，出现以下错误：

其他资料 下面是我的路径系统变量的图片：

---

adb

不在您的

%PATH%

上；确保添加

adb.exe

所在的文件夹（通常

$ANDROID\u HOME/platform tools

，其中

$ANDROID\u HOME

是您的ANDROID SDK安装目录，通常

C:\Users\your.Name\AppData\Local\ANDROID\SDK

，您可以在Windows cmd控制台中运行

where adb

命令来查找它）转到系统环境变量下的

%PATH%

，然后重新启动WebStorm

---

您还需要根据错误消息中的建议定义

%ANDROID\u SDK\u ROOT%

环境变量

只需添加，windows环境变量区分大小写，添加

%LOCALAPPDATA%\ANDROID\SDK

就像react本地网站所说的那样将不起作用，您还需要添加

%LOCALAPPDATA%\ANDROID\SDK

，如果你看不到你的AppData文件夹，给所有新手一个建议。在文件资源管理器中，转到查看->并选中隐藏文件框。这是一个隐藏的文件夹。
