尝试运行一个使用 python 后端的外部程序并在安装了 canopy 包之后（也尝试了“手动”pyface 构建之后），我不断收到一个奇怪且看似非常基本的错误。任何建议都将受到欢迎！

Traceback (most recent call last):

    load_entry_point('melview==1.0', 'console_scripts', 'melview')()

这个答案对您来说可能已经很晚了，但是为了大家的利益而在此发布。

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