ubuntu下android studio执行gradle报错

Question

在ubuntu15.10下搭建了android开发环境,打开demo项目时报gradle无法找到。
提示如下：

Error:Could not find com.android.tools.build:gradle:2.14.1.
Searched in the following locations:
file:/home/terrrrrrgl/dev/android-studio/gradle/m2repository/com/android/tools/build/gradle/2.14.1/gradle-2.14.1.pom
file:/home/terrrrrrgl/dev/android-studio/gradle/m2repository/com/android/tools/build/gradle/2.14.1/gradle-2.14.1.jar file:/root/.m2/repository/com/android/tools/build/gradle/2.14.1/gradle-2.14.1.pom file:/root/.m2/repository/com/android/tools/build/gradle/2.14.1/gradle-2.14.1.jar https://jcenter.bintray.com/c...

我查看了一下发现gradle实际是安装在了/root/.gradle/ 下面，请问该如何设置让gradle正常运行起来

补充：android-studio的setting里gradle设置选择的是 Use default gradle wrapper.

Answer 1

export PATH=$PATH:/root/.gradle/bin
