이오니아 코르도바 빌드 안드로이드가 작동하지 않습니다

Question

이온 및 코도바를 설치했습니다.

빌드를 확인하고 IOS가 완벽하게 작동하지만 Android가 작동하지 않는 경우 에뮬레이션합니다.

내가 가진 메시지는 다음과 같습니다

I rm 안드로이드 플랫폼과 그것을 다시 설치하지만 여전히 같은 문제가있어. 어떤 생각이 어떻게 작동하게 할 수 있습니까?

Answer 1

you can follow this steps:-- 

Open Terminal.app. 
Create a new directory sudo mkdir /usr/local/gradle. 
Extract the downloaded Gradle distribution archive by executing sudo unzip gradle-4.0.2-all.zip -d /usr/local/gradle. 
Edit .bash_profile in your home directory to add GRADLE_HOME variable with the following line export GRADLE_HOME=/usr/local/gradle/gradle-4.0.2 
Also update the PATH variable to include $GRADLE_HOME/bin. If you don’t already have the PATH variable add the following line export PATH=$GRADLE_HOME/bin:$PATH 
Run source ~/.bash_profile to executes the update version of .bash_profile. Or you can open a new Terminal.app to make this changes active.

를 따라가 나는 문제를 발견했다. 나는 brew install gradle를 다시했다. 그러나 이번에 나는 나의 vpn를 연다. 내가 중국에 있기 때문에 일부 코드는 vpn없이 다운로드 할 수 없습니다. 이제는 작동 중입니다
