我试图从github运行离子2中的应用程序，但在运行之后：
sudo ionic run android
我得到了：
Failed to notify ProjectEvaluationListener.afterEvaluate(), but primary configuration failure takes precedence.
java.lang.IllegalStateException: buildToolsVersion is not specified.

我已经尝试了帖子Ionic Android build: java.lang.IllegalStateException: buildToolsVersion is not specified，但没有运气。我还试图再次添加/添加平台，我确定android-sdk链接正确（版本25.2.3）。
