Ubuntu 14.04上的qt4剪贴板错误

Question

试图运行一个使用python后端的外部程序，在安装了canopy包之后（在尝试了"手动"pyface构建之后），我不断收到一个奇怪的、似乎非常基本的错误。欢迎提出任何建议！

Traceback (most recent call last):

NotImplementedError: the qt4 pyface backend doesn't implement Clipboard

这个答案对你来说可能已经很晚了，但为了每个人的利益，在这里发布。

这个问题主要是因为pyface setup.py脚本中缺少"traitsui"依赖项。您可以通过手动安装traitsui来解决此问题。
