\android\build.gradle 行中的意外令牌：12：意外令牌：}

Question

我正在嘗試使用 react-native 運行一個項目。

我遵循了Viro 網站中給出的所有步驟。

當嘗試使用react-native run-android構建項目時，我收到以下錯誤：

Could not compile build file '\ARDemo\android\build.gradle'.

啟動失敗：構建文件'\ARDemo\android\build.gradle'：12：意外令牌：}@第12行，第1列。}^

1 個錯誤

• 嘗試：使用 --stacktrace 選項運行以獲取堆棧跟蹤。 使用 --info 或 --debug 選項運行以獲得更多日志 output。 運行 --scan 以獲得完整的見解。

您在buildscript {之后缺少repositories { {

嘗試這個：

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

buildscript {
    repositories { // --> this was missing
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.0'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
} 

allprojects {
    // Workaround for https://issuetracker.google.com/117900475
    // Remove when upgrading to AGP 3.4 or higher
    configurations.matching { it.name == '_internal_aapt2_binary' }.all { config ->
        config.resolutionStrategy.eachDependency { details ->
            details.useVersion("3.5.0-alpha03-5252756")
        }
    }
    repositories {
        mavenLocal()
        maven {
            url 'https://maven.google.com/'
        }
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url("$rootDir/../node_modules/react-native/android")
            google()
            jcenter()
            maven { url 'https://www.jitpack.io' }
        }
    }
