Question

按照教程here，我无法在模拟器中运行该应用程序。当我从DOS提示符执行react-native run-android命令时，这是我得到的错误：

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring root project 'AwesomeProject'.
> Could not resolve all dependencies for configuration ':classpath'.
   > Could not resolve com.android.tools.build:gradle:2.2.3.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug
option to get more log output.

我尝试的事情：

编辑build.gradle文件并从classpath更改classpath＆＃39; com.android.tools.build：gradle：2.2.3＆＃39; to com.android.tools.build:gradle:3.3.0' （我使用Android Studio安装的版本）。
已验证jcenter（）在buildcript和allprojects下的build.gradle中列为存储库

Answer 1

尝试将其设置为2.3.0

奇怪的是，我看不到那个路径中的任何2.2.3，但我可以看到2.3.0 http://repo1.maven.org/maven2/com/android/tools/build/gradle/

Answer 2

我使用react-native cli重新创建了项目，问题似乎正在纠正。我应该注意到，当我最初创建项目时，我相信我没有安装android studio，所以也许这与它有关，不确定。

react-native - 无法运行示例应用程序
