Ionic framework ionic 3:失败：生成失败，出现异常

我正在尝试为爱奥尼亚3项目创建Android应用程序包。运行命令/gradlew bundle时，我得到以下错误。在.bash\u概要文件中，我添加了以下内容：

export ANDROID_HOME=/Users/dome/Library/Android/sdk
export PATH=$PATH:$ANDROID_HOME/tools 
export PATH=$PATH:$ANDROID_HOME/tools/bin
export PATH=$PATH/:$ANDROID_HOME/platform-tools

export ANDROID_HOME=/Users/dome/Library/Android/sdk
export PATH=$PATH:$ANDROID_HOME/tools 
export PATH=$PATH:$ANDROID_HOME/tools/bin
export PATH=$PATH/:$ANDROID_HOME/platform-tools

渐变版本是：4.4.1
