Ubuntu14.04上的qt4剪贴板错误

Question

尝试运行一个使用python后端的外部程序，并且在安装了canopy包之后(也尝试了“手动”的pyface构建)，我总是得到一个奇怪的、看起来非常基本的错误。任何建议都将非常受欢迎！

Traceback (most recent call last):
  File "/usr/local/bin/melview", line 9, in <module>
    load_entry_point('melview==1.0', 'console_scripts', 'melview')()

NotImplementedError: the qt4 pyface backend doesn't implement Clipboard

这个答案对你来说可能太晚了，但为了大家的利益，请在这里发帖。

该问题主要是由于pyface setup.py脚本中缺少"traitsui“依赖项造成的。您可以通过手动安装traitsui来解决此问题。
