新人求助！cocos creator偏好设置问题，安装了andriod studio仍需要配置ant路径

Creator 2.x
#1

新手求助
文档上写偏好设置
ANT Path（如使用 Android Studio，这一步可以跳过），请选择下载并解压完成的 Apache Ant 路径，需要设置到 ant 安装目录内的 bin 目录下，选定的路径中应该包括一个名叫 ant 的可执行文件。
然而安装了andriod studio不设置ant路径根本不能保存，是什么意思呢？是不是有一个地方可以设置andriodstudio路径呢
成功保存了之后在项目构建的时候失败并且显示未配置ANT路径？

#2

如果原生环境配置不完全，点击其他选项可以保存。

#3

但是构建andriod项目的时候显示没有配置ant？
Build Failed: Error: [ANT Root] is empty, please set [ANT Root] in Preferences.

然后呢

#5

其实实在没法子就把它给配置了呗，我报错也是这样解决的：

然后不就可以编译了。
