matplotlib 需要 pyparsing

问题描述

我正在尝试使用matplotlib绘制一些数据.导入库时，出现错误:

I am trying to plot some data using matplotlib. When importing the library, I get the error:

ImportError: matplotlib requires pyparsing

我使用 easy_install pyparsing 安装了pyparsing，但是错误不断出现.

I installed pyparsing using easy_install pyparsing, but the error keeps appearing.

我该如何解决这个问题?或者，是否有任何替代 matplotlib 来使用 Python 绘制内容的方法?

How can I solve this problem? Alternatively, is there any alternative to matplotlib to plot stuff with Python?

sys.path 返回:

['', 'C:\\Python27\\lib\\site-packages\\spyderlib\\utils\\external', 'C:\\Windows\\system32\\python27.zip', 'C:\\Python27\\lib\\site-packages\\Orange\\orng', 'C:\\Python27\\DLLs', 'C:\\Python27\\lib', 'C:\\Python27\\lib\\plat-win', 'C:\\Python27\\lib\\lib-tk', 'C:\\Python27', 'C:\\Python27\\lib\\site-packages', 'C:\\Python27\\lib\\site-packages\\win32', 'C:\\Python27\\lib\\site-packages\\win32\\lib', 'C:\\Python27\\lib\\site-packages\\Pythonwin', 'C:\\Python27\\lib\\site-packages\\wx-2.8-msw-unicode', 'C:\\Python27\\lib\\site-packages\\IPython\\extensions']

尝试导入pyparsing返回错误:
