python - Enthought mlab non-framework build of python does not have access to screen

Question

Using Enthought Canopy v1.4 on Mac (Mavericks) I have Canopy setup as my default Python environment.

Whenever I try to call mlab.show() or mlab.savefig() it fails with:

This program needs access to the screen.
Please run with a Framework build of python, and only when you are
logged in on the main display of your Mac.

Python is loaded from ~/Library/Enthought/Canopy_64Bit/System/Python which is a symlink to Applications/Canopy/appdata/canopy-1.4.0.1938.macosx-x86_64/Canopy/Contents/Python

Is there any way I can keep using Canopy (for its easy install of Mayavi/mlab) and use a Framework build of python for Terminal use?

已知错误，在下周的 Canopy 1.4.1 中修复。此处的解决方法：https: //support.enthought.com/entries/22601196-wxPython-2-8-and-2-9

编辑：我对您报告的错误消息做出了快速响应，但更仔细地阅读了一些要点：

1）如果您正在加载Canopy_64Bit/System/Python，那么这是一个错误，而不是引用的文章所指向的内容（应该是 Canopy_64Bit/User/bin/python）。（sys.prefix应该指向用户）。

2) 无需将 Canopy 设为终端中的默认 Python。只需在 Canopy 首选项中取消设置，从 Canopy GUI 运行 Canopy User Python，如果您确实想在终端中运行 Canopy User Python，只需使用 Canopy 的工具 / Canopy 终端命令（Canopy 1.4 中的新功能）。
