我是较新的使用wxPython的人，首先，我使用命令pip install wxPython来安装wxPyhton：

pip install -U wxPython

Requirement already up-to-date: wxPython in c:\program files\python\python37\lib\site-packages (4.0.3)

Requirement already satisfied, skipping upgrade: six in c:\program files\python\python37\lib\site-packages (from wxPython) (1.11.0)

Requirement already satisfied, skipping upgrade: PyPubSub in c:\program files\python\python37\lib\site-packages (from wxPython) (4.0.0)

然后，我尝试运行此代码以显示GUI窗口，并从wxPyhton示例获取源代码：

# set_size.py

import wx

class Example(wx.Frame):

def __init__(self, parent, title):

super(Example, self).__init__(parent, title=title, size=(350, 250))

def main():

app = wx.App()

ex = Example(None, title='Sizing')

ex.Show()

app.MainLoop()

if __name__ == '__main__':

main()

但是我收到错误消息“ import的未定义变量：Frame”，接下来该怎么办？
