由于这个问题，我无法在Genymotion上运行项目。

Answer 1

您必须在react native项目根目录的 local.properties 文件中设置Android SDK的路径。建议您看看这个问题的第二个答案SDK location not found. Define location with sdk.dir in the local.properties file or with an ANDROID_HOME environment variable

Answer 2

如错误消息中所述，没有安装Android SDK。请尝试安装android SDK，并确保ANDROID_SDK_ROOT已定义并指向正确的目录。

简单的方法，请尝试安装android studio
