react-native-safe-area-context build.gradle 文件出现错误且未指定compileSdkVersion

它的错误在这个文件中： C:\Users\sawan\OneDrive\Desktop\Unsplash pp 颂歌模块 eact-native-safe-area-context ndroid uild.gradle

//rest of the code ...
android {
compileSdkVersion getExtOrDefault('compileSdkVersion', 30)

// Used to override the NDK path/version on internal CI or by allowing
// users to customize the NDK path/version from their root project (e.g. for M1 support)
if (rootProject.hasProperty("ndkPath")) {
    ndkPath rootProject.ext.ndkPath
}
if (rootProject.hasProperty("ndkVersion")) {
    ndkVersion rootProject.ext.ndkVersion
}

defaultConfig {
    minSdkVersion getExtOrDefault('minSdkVersion', 16)
    targetSdkVersion getExtOrDefault('targetSdkVersion', 28)
    versionCode 1
    versionName "1.0"
    buildConfigField "boolean", "IS_NEW_ARCHITECTURE_ENABLED", isNewArchitectureEnabled().toString()

    ndk {
         abiFilters (*reactNativeArchitectures())
     }
}// rest of the code ....

这是我来自 ndroid 的 build.gradle 文件

buildscript {
ext {
    buildToolsVersion = "33.0.0"
    minSdkVersion = 21
    compileSdkVersion = 33
    targetSdkVersion = 33

    // We use NDK 23 which has both M1 support and is the side-by-side NDK version from AGP.
    ndkVersion = "23.1.7779620"
    // kotlin_version = '1.5.20' //
}
repositories {
    google()
    mavenCentral()
}
dependencies {
    classpath("com.android.tools.build:gradle:7.3.1")
    classpath("com.facebook.react:react-native-gradle-plugin")
    // classpath("org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version") //
}}

不知道错误是在这个路径还是build.gradle文件中

Answer 1

与 “gradle 缓存”有关。

只需清理 gradle 缓存，例如：

rm -rf ~/.gradle

然后

yarn android

或

npx react-native run-android

最初由me（@Pranav-yadav）在这里发布：https://github.com/th3rdwave/react-native-safe-area-context/issues/391#issuecomment-1565925679

P.S.：清理 gradle 缓存后，第一次构建时，它将下载所需的 gradle 文件，因此，第一次构建将消耗“更多”带宽。之后它将像往常一样构建。

在您的项目中

android>gradle>包装器>gradle-wrapper.properties 降低你的 gradle 版本（例如 8.6 到 8.2.1） 比运行你的项目 npx react-native start --reset-cache
