Question

尝试在我的beaglebone black（Cloud9 GNOME Image 2013.09.04）上安装Flask时，遇到模块ast的ImportError（安装Werkzeug模块）。我有Python 2.7.3版本，所以这个内置版本应该不存在？

以下是日志：

    import ast

ImportError: No module named ast

我尝试在此主板上定期导入ast，但我无法这样做。很可能它根本不存在，但我的python和python-dev被报告为最新。

帮助！

Angstrom BeagleBone图像有一个奇怪的，有点破碎的Python 2.7 IIRC版本，BeagleBoard.org不再支持它们。您应该真正升级到BeagleBoard.org（http://beagleboard.org/latest-images）维护和支持的当前Debian映像之一 - 我已经毫不费力地使用了烧瓶。

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