如何为 Python 安装 wxversion

Question

我正在试验 "SPy" Spectral Python 库，使用 PyCharm，我已经到了它告诉我找不到 wxversion 的地步。如何安装 wxversion？

总的来说，我是 Python 的新手，我是不是做错了什么？这是我的代码：

import matplotlib
#matplotlib.use('WX')    #Replaced by editing matplotlibrc
from spectral import *

img = open_image('92AV3C.lan')
print img.__class__
print
print img
print
print img.shape
pixel = img[50,100]
print
print pixel.shape
band6 = img[:,:,5]
print
print band6.shape
print


arr = img.load() 
print arr.__class__
print
print arr.info()
print
print arr.shape

view = imshow(img, (29, 19, 9))

所有内容均来自此处的 SPy 指南：http://www.spectralpython.net/user_guide.html

这是错误：

Traceback (most recent call last):

    raise ImportError(missingwxversion)
ImportError: Matplotlib backend_wx and backend_wxagg require wxversion, which was not found.

此外，还有其他 guides/tutorials SPy 吗？

您只需从 www.wxpython.org 下载即可在 Mac 上安装 wxPython。请注意他们网站上的以下通知：

注意：此安装程序未由 Apple 签名，因此默认情况下您的 Mac 会告诉您它已损坏并且不会安装它。您可以通过暂时放松系统偏好设置中的安全设置来解决这个问题。在“安全和隐私”部分中，将 "Allow applications downloaded from" 设置为 "Anywhere."

我已经按照他们的指示进行操作，一旦我更改了这些设置，在 Mac (Yosemite) 上安装 wxPython 就没有问题了。
