wxPython导入错误

Question

我在Python中找出错误消息时遇到了麻烦.

昨天,我使用最新的EPD软件包安装了python,并使用适用于Mac OS的wxPython2.9-osx-cocoa-py2.7软件包安装了wxPython2.9.然后我把wx添加到我的PYTHONPATH中.

export WXDIR=/usr/local/lib/wxPython-2.9.1.1/lib/python2.7/site-packages/wx-2.9.1-osx_cocoa
export PYTHONPATH=$WXDIR
export PYTHONPATH=$PYTHONPATH:$WXDIR/tools

但是当我尝试运行东西时,我收到此错误:

In [14]: import matplotlib.pyplot

ImportError: Matplotlib backend_wx and backend_wxagg require wxPython >=2.8

我可以成功导入wx,所以我不知道是什么问题.我在PYTHONPATH中遗漏了什么？

Answer 1

在Ubuntu 12.04中,可以通过运行该命令来解决此问题

sudo apt-get install libjpeg62

我意识到这可能在这里没有用,但是我想在teh interwebz上的某个地方记录它,所以当我再次遇到这个问题时我可以找到它,这无疑会发生.

Answer 2

我使用的是Ubuntu 13.10,Canopy 1.2和PyCharm 3.0.2.当尝试使用matlablib时,它总是抱怨"Matplotlib backend_wx和backend_wxagg需要wxPython> = 2.8".确定我正在使用wxPython 2.8.然后我尝试了本页描述的所有方法,但它们都不适合我.

事实证明,它可以通过修改matplotlibrc文件来解决.有一条线:

后端:WXAgg

事实上,我们可以将后端更改为我们喜欢的任何内容,然后将其更改为TKAgg,这对我来说效果很好.

Answer 3

在导入任何 wx 模块之前选择您的 wx 版本

import wxversion
wxversion.select('2.8')

上面的代码应该放在前面import wx
