使用Pydev在Eclipse中编译错误

Question

Iam在Ubuntu平台中是Eclipse的新手，所以我想在Python中编程，但是当我使用Run编译代码时，向导显示并要求我运行为“Ant Build”，还不如蟒蛇，所以当我选择为Ant构建运行表明，这些短信给我：

，这是代码卡：

那么如何解决这个问题???

在PyDev中运行Python模块的最简单方法是在对焦编辑器时按F9。

入门指南有一个专用于该章赋予与PyDev的运行模块的更多提示：http://pydev.org/manual_101_run.html（理想情况下，你应该从一开始就按照它：http://pydev.org/manual_101_root.html）
