Python Eclipse在重新安装后无法找到库

我不得不重新安装操作系统，现在我无法在EclipseIDE上加载我的旧项目。起初它没有找到GAE源文件夹，因为它不在我创建项目时所在的位置，所以我只是将变量$GOOGLE_APP_ENGINE改为它真正所在的位置

但现在看来，在新版本的GAE源代码中，库文件夹有不同的名称，Eclipse无法找到它们

如何使Eclipse修改旧项目的信息，以便更新库文件夹名称

非常感谢。

如果您使用的是python，则需要在Project->Properties->External Libraries上设置正确的路径，或者编辑.pydevproject文件。我几天前做的，只是用下面的替换掉那些找不到的

<pydev_project>
....

不会在Eclipse的窗口->首选项->谷歌->应用引擎帮助中设置正确的谷歌库路径吗？对于旧项目，它们的路径仍然错误。不会在Eclipse的窗口->首选项->谷歌->应用引擎帮助中设置正确的谷歌库路径吗？对于旧项目，它们的路径仍然错误。它工作正常，谢谢！实际上我已经试过了，但它仍然失败了，因为我没有删除错误的路径，谢谢提示：-）它成功了，谢谢！实际上我已经试过了，但它仍然失败了，因为我没有删除错误的路径，谢谢提示：-）
