我配置了离子android开发环境。我可以在Android Studio 2.2.2中打开我的Android项目,并在模拟器中启动应用程序,并且它可以正常工作。离子:无法从终端启动android模拟器

但是,如果我去我的终端,去我的离子项目。并建立或模仿机器人,如:

ionic build android 
ionic emulate android 

我得到一个错误:

Error: /Users/alex_fimm_dev/Desktop/Projects/ionic/myApp2/platforms/android/gradlew: Command failed with exit code 1 Error output: 
FAILURE: Build failed with an exception. 

* What went wrong: 
A problem occurred configuring root project 'android'. 
> Could not resolve all dependencies for configuration ':_debugApk'. 
    > A problem occurred configuring project ':CordovaLib'. 
     > Could not resolve all dependencies for configuration ':CordovaLib:classpath'. 
     > Could not find com.android.tools.build:gradle:2.2.2. 
      Searched in the following locations: 
       https://repo1.maven.org/maven2/com/android/tools/build/gradle/2.2.2/gradle-2.2.2.pom 
       https://repo1.maven.org/maven2/com/android/tools/build/gradle/2.2.2/gradle-2.2.2.jar 
      Required by:

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

同样的项目运行良好Android上的工作室。
