在Python27中安装wxPython

Question

I've been trying to install wxPython in Python27.

I typed below command in Python27 dir, and installed it.

pip install wxPython

I expected the wxPython would be installed in Python27.

But, the wxPython doesn't work in Python27.

When I tried to import the wx, I got below error.

On the other hand, it works for Python3.

How could I get proper wxPython version for Python27?

The installed wx version is this.

This is the result of the command python -m pip install wxPython .

Think I understand whats happening now: Your Python 3.7 almost always "wins" against 2.7 (due to the way its installed; we will not know because we cannot see how you activate one over the other according to your screenshots). At any rate, when you do

C:\Python27\python.exe

you will run Python 2.7. However, when you do

C:\Python27\pip

this will call the pip in the 3.7 (!), because it has precedence on %PATH% before the 2.7 one. If you would do C:\\Python27\\scripts\\pip.exe you would call pip/install into 2.7! This is by the way what @RobinDunn suggested! If we look at your newest screenshot, we can see already that both 2.7 and 3.7 have wxPython installed.

So, accordingly, if you try:

C:\Python27\python.exe -c "import wx;print(wx.version())"

you should indeed be able to prove to yourself that the 2.7 has its wx properly running!
