Matplotlib坑爹依赖安装全解

在安装matplotlib环境时遇到了无数坑爹问题，汇总一下..希望给迷路的同学提供帮助..

Traceback (most recent call last):

  File "", line 1, in

    import matplotlib

  File "D:\Python27\lib\site-packages\matplotlib\__init__.py", line xx, in

    raise ImportError("matplotlib requires dateutil")

ImportError: matplotlib requires six

easy_install six

0x01

Traceback (most recent call last):

  File "", line 1, in

    import matplotlib

  File "D:\Python27\lib\site-packages\matplotlib\__init__.py", line 111, in

    raise ImportError("matplotlib requires dateutil")

ImportError: matplotlib requires dateutil

easy_install dateutil会安装失败，应该输入easy_install python-dateutil

0x02

Traceback (most recent call last):
  File "", line 1, in
    import matplotlib
  File "E:\Python 2.7.9\lib\site-packages\matplotlib\__init__.py", line 140, in
    raise ImportError("matplotlib requires pyparsing")
ImportError: matplotlib requires pyparsing

easy_install pyparsing

0x03

Traceback (most recent call last):
  File "", line 1, in
    import matplotlib
  File "E:\Python 2.7.9\lib\site-packages\matplotlib\__init__.py", line 180, in
    from matplotlib.cbook import is_string_like
  File "E:\Python 2.7.9\lib\site-packages\matplotlib\cbook.py", line 33, in
    import numpy as np
ImportError: No module named numpy

在有VS2012或者2011的环境下，easy_install numpy会提示Unable to find vcvarsall.bat，因为Python27默认编译器为vs2008，若环境中存在VS2012输入SET VS90COMNTOOLS=%VS110COMNTOOLS%；若环境为VS2010则输入SET VS90COMNTOOLS=%VS100COMNTOOLS%后，再进行easy_install numpy

若仍报错，直接http://sourceforge.net/projects/numpy/files找相应版本下载numpy.exe后安装即可

0x04

pip出现Fatal error in launcher:unable to create process using xxx

在系统变量加入python目录后执行python -m pip install xxx

0x05

如果你的python是64位的，0x04红色字体方法不可行，需要下载64位的numpy，

在http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy下载64位numpy.whl之后，切换到下载目录，pip install numpyxxx.whl即可

终于，大功告成！
