这是 package.json：

这个项目几天前就可以建成。但是，没有任何更改，我面临上述错误。

我用谷歌搜索并找到了以下页面：

react-native run-android：守护进程启动失败

无法编译和运行我的本机应用程序

我确实尝试了它们，但它们都不起作用。

有任何想法吗？？？？？？

Answer 1

解决方案1：删除android/app/build文件夹并尝试重新构建。它应该工作

解决方案2：运行 npm i --save @react-native-community/cli-platform-android

Answer 2

1. 首先确保你在 cmd admin
2. 跑 cd android && gradlew clean
3. 如果它给你错误，gradlew clean 然后转到project/android/app/build/intermediates/并删除signing_config文件夹
4. 跑 gradlew clean
5. 跑 react-native run-android

Answer 3

很可能您的某些依赖项发生了更改，进行了重大更新并覆盖了您的某些依赖项。因此，请执行以下操作：

1. 从 package.json 中删除所有 ^。这对 NPM 或 YARN 来说意味着可以更新到更新版本的软件包。通常，您不希望出现这种情况，因为这种情况可能会发生。

2. 核对你的node_modules并重新安装所有东西。
