无法导入 'ast'：Angstrom 上的 Flask 安装（Beaglebone 黑色）

Question

尝试在我的 beaglebone black (Cloud9 GNOME Image 2013.09.04) 上安装 Flask 时，它遇到模块 ast（安装 Werkzeug 模块）的 ImportError。我有 Python 2.7.3 版本，所以这个内置函数不应该已经存在了吗？

这是日志：

    import ast

ImportError: No module named ast

我尝试在此版块中以常规方式导入 ast，但我无法这样做。它很可能根本不存在，但我的 python 和 python-dev 被报告为最新的。

求助！

Angstrom BeagleBone 图像有一个奇怪的，有点破损的 Python 2.7 IIRC 版本，并且 BeagleBoard.org 不再支持它们。您真的应该升级到 BeagleBoard.org (http://beagleboard.org/latest-images) 维护和支持的当前 Debian 映像之一 - 我已经在这些映像上毫无问题地使用了 flask。
