wxpython-phoenix 在 osx/ipython/pycharm 上需要 python 框架

wxpython-phoenix requires python framework on osx/ipython/pycharm

运行 wxpython-phoenix website throws a known error on osx. Hints at possible solutions can be found here, and here 上提供的示例 hello-world 代码,但 none 似乎适用于 ipython 和 pycharm。

问题:如何解决这个已知错误,使用 pycharm 中的 ipython?

设置:

OSX 10.12.5 塞拉
ipython conda venv 中的 3.7.1
pycharm CE 2018.3
(也从命令行和 jupyter notebook 失败)

代码运行:(来自wxpython入门页面)

import wx
app = wx.App()
frm = wx.Frame(None, title="Hello World")
frm.Show()
app.MainLoop()

错误信息

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.

注:本题类似于:
- that 一个用于 python2.7,但没有收到答复
- 为 python 之外的 pycharm
提供过时修复 其他问题,如 this one,在 wxpython 的新版本中已过时。

使用 conda 环境时,您需要安装 python.app 包,然后使用 pythonw 到 运行 使用 wxPython 的应用程序。

在osx上,命令行为:(如图here

conda install -c anaconda python.app

您将看到以下消息;确认继续。

The following packages will be SUPERSEDED by a higher-priority channel:

    python.app: 2-py37_9 --> 2-py37_9 anaconda

pycharm,需要更改项目解释器:

--> 转到:

preferences
  project interpreter
    add interpreter
      conda environment
        anaconda (or anaconda3)
          bin
            pythonw 
select pythonw
apply
ok
