尝试在我的 beaglebone black（Cloud9 GNOME Image 2013.09.04）上安装 Flask 时，遇到模块的 ImportError ast（安装 Werkzeug 模块）。我有 Python2.7.3版本，所以这个内置不应该已经存在？

以下是日志：

        import ast
    ImportError: No module named ast
    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):

  File "<string>", line 16, in <module>

  File "/tmp/pip-build-root/Werkzeug/setup.py", line 56, in <module>

    import ast

ImportError: No module named ast

我尝试在此板上以常规方式导入ast，但无法这样做。很可能它根本不存在，但我的 python 和 python-dev 被报告为最新的。

帮助！

Angstrom BeagleBone 图像有一个奇怪的、有点损坏的 Python 2.7 IIRC 构建，BeagleBoard.org 不再支持它们。您真的应该升级到由 BeagleBoard.org ( http://beagleboard.org/latest-images )维护和支持的当前 Debian 映像之一——我在那些上使用了烧瓶没有任何问题。
