我尝试了一切，但它在 React-Native 中显示了这个错误

Question

我在完成我的 react js 后才开始学习 React Native，每次创建新的 React-Native 项目时都会显示此错误，我失去了学习 React-Native 的希望

Answer 1

如果您在运行 react-native run-android 时收到错误消息，请尝试转到 android 文件夹并清理 gradlew cd android && ./gradlew clean 您也可以尝试运行chmod +x gradlew

您的项目应该已成功启动

或访问here

Answer 2

首先确保您的环境设置正确，正如documentation 所说。

如果是这样，请尝试以下方法：

1. cd android 然后./gradlew clean
2. 否则尝试删除node modules 并运行npm install

Answer 3

检查您是否需要像 build.gradle 一样编辑 AndroidManifest.xml 中的 uses-sdk

<uses-sdk android:minSdkVersion="11" android:targetSdkVersion="14" />

还有 android 部分，尤其是 build.gradle 文件中的 minSdkVersion 和 targetSdkVersion

android {
    compileSdkVersion 17
    buildToolsVersion "17.0.0"

    defaultConfig {
        minSdkVersion 11
        targetSdkVersion 14
    }
}
