React native React本机应用程序未在android模拟器上生成：任务：应用程序：packageDebug失败

我正在尝试使用以下方式运行我的react本机应用程序：

• 反应本机（0.61.1）
• android模拟器（Pixel 2 API 29）

但是在运行

react native run android

之后，我遇到了以下错误：

> Task :app:packageDebug FAILED

FAILURE: Build failed with an exception.

* Where:
Script '/Users/Projects/App/node_modules/react-native/react.gradle' line: 278

* What went wrong:
Execution failed for task ':app:packageDebug'.
> react_a3lulyqnn3g84dqjhcnav59s2$_run_closure4$_closure6$_closure10$_closure18

Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Exception is:

我试图：

• 格雷德卢清洁酒店
• 删除我的节点\u模块文件夹

构建几乎达到100%，但在最后一秒出错

---

但这些都不起作用。任何帮助都将不胜感激

我的

buildToolsVersion

错误

buildscript {
    ext {
        buildToolsVersion = "29.0.3"
        ...
    }
    ...
}

“29.0.3”不存在。
在检查最后一个可用版本后，我将其更改为

buildscript {
    ext {
        buildToolsVersion = "29.0.0"
        ...
    }
    ...
}
