compilesdkversion未在Expo Run Android上指定

Question

我正在尝试运行命令expo Run：Android，但是我会遇到此错误。

* What went wrong:
A problem occurred configuring project ':expo'.
> compileSdkVersion is not specified. Please add it to build.gradle

但是在文件build.gradle中指定了。 我还有其他错误，所以我尝试重新安装，目前安装了Java 8 Update 333。 我尝试了命令rm -rf〜/.gradle/caches，但它无济于事 请问问题在哪里？

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    ext {
        buildToolsVersion = "29.0.3"
        minSdkVersion = 21
        compileSdkVersion = 29
        targetSdkVersion = 29
    }
    repositories {
        google()
        mavenCentral()
        jcenter()
    }
    dependencies {
        classpath("com.android.tools.build:gradle:4.1.0")
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        mavenLocal()
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url(new File(["node", "--print", "require.resolve('react-native/package.json')"].execute(null, rootDir).text.trim(), "../android"))
        }
        maven {
            // Android JSC is installed from npm
            url(new File(["node", "--print", "require.resolve('jsc-android/package.json')"].execute(null, rootDir).text.trim(), "../dist"))
        }

        google()
        mavenCentral()
        jcenter()
        maven { url 'https://www.jitpack.io' }
    }
}

Answer 1

我遇到了同样的问题，事实证明这是一个错误的Android_home环境变量。仔细检查是否将变量点指向正确的位置。

Answer 2

重新启动您的计算机。重新开放项目后，转到file＆gt;与gradle文件同步项目。这对我有用。

它也可能有助于从磁盘中重新加载。
