project(watip)下，src folder下存在util ->TooLog.py - >GenLog类，想在src folder 下action -> LogInAction.py 下引用GenLog类:from util.TooLog import GenLog，此时报：Unresolved import,
解决方法如下：
1.在project（watip）右击打开菜单 ->选择properties->选择"PyDev-Interpreter/Grammar"->点击链接"Click here to configure an interpreter not listed." -> 在"Libraries"tab内，点击"new folder"，加入util的上引目录"src"的路径->点击"ok"
3.重启eclipse.
