Python: installation of wx fails on Mac

Question

I am running a python2 package that uses wx on a MacBook. I'm running python 2.7.10. When I run the package:

con@company_computer:~/dir/pasta$ python run_pasta_gui.py 
Traceback (most recent call last):
  File "run_pasta_gui.py", line 27, in <module>
    import wx
ImportError: No module named wx

so I try to install wx following advice from Python ImportError: No module named wx

I try to install via pip as also suggested on https://wxpython.org/pages/downloads/index.html :

pip install -U wxPython

&

sudo pip install wxPython

&

sudo -H pip install wxPython

but all of these say that it's already installed:

Requirement already satisfied: wxPython in /usr/local/lib/python2.7/site-packages (4.0.7.post2)
Requirement already satisfied: pillow in /usr/local/lib/python2.7/site-packages (from wxPython) (6.2.2)
Requirement already satisfied: six in /usr/local/lib/python2.7/site-packages (from wxPython) (1.11.0)
Requirement already satisfied: numpy<1.17; python_version <= "2.7" in /usr/local/lib/python2.7/site-packages (from wxPython) (1.14.2)

and yet I get the original error back when I try to run run_pasta_gui.py

I was able to get this done on my Ubuntu VM by sudo apt-get install python-wxtools but this obviously isn't available on a Mac.

Following Unable to import a module that is definitely installed I've tried sudo chmod -R ugo+rX /usr/local/lib/python2.7/site-packages/ but I'm still unable to access the wx package.

How can I get wx working for my python2 installation?

我在 venv 中运行安装，并且能够导入并列出模块
