我刚刚使用react-native init -project name-下载了新项目,但是无法在模拟器中运行它(react-native run-android)
它在命令提示符下显示:
info JS server already running.
info Building and installing the app on the device (cd android && gradlew.bat app:installDebug)...
> Task :app:preDebugBuild

我尝试更改build:gradle版本3.0.1,这将是另一个错误,因此我认为我需要升级我的构建包或降低我的本机版本。现在,我正在尝试从android studio更新我的android sdk。
这是我当前的构建gradle
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
ext {
buildToolsVersion = "28.0.3"
minSdkVersion = 16
compileSdkVersion = 28
targetSdkVersion = 28
supportLibVersion = "28.0.0"
}
repositories {
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 {
repositories {
mavenLocal()
google()
jcenter()
maven {
// All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
url "$rootDir/../node_modules/react-native/android"
}
}
}
如果我想更新构建gradle,我会缺少什么?
