Question

我尝试使用react-native init NewProject命令创建新项目。该项目已成功创建，但当我尝试在genymotion android模拟器上运行项目：react-native run-android时，我得到以下输出：

>C:\IdeaProjects\proj>react-native run-android

我已经成功安装：

有非常好的文档available here。请参阅此处的“使用本机代码构建项目”部分。

您可能需要设置node，watchman以及其他一些依赖项，例如python2，react-native-cli。还有一些其他配置，具体取决于您使用的是Mac还是Windows。

您可能也想看看Create-React-Native-App。这是最容易上手的推荐方式。

Answer 2

您无法使用旧版构建工具构建新SDK。构建工具的主要版本应该不小于SDK。工作设置示例：

Android SDK Platform 25
Android SDK Build-Tools 25.0.3
