Python Installation matplotlib,six,dateutil,pyparsing Complete process

Because matplotlib needs to rely on many other scientific computing third-party libraries, one installation is required.

1, install Matplotlib

Download directly from the website: http://matplotlib.sourceforge.net/

I found an. exe after the installation is complete, the direct import matplotlib,

The error is as follows:

And then we're installing six.

2, install six

Official website Download: http://www.pythonhosted.org/six/

I downloaded the six-1.8.0 source package, after decompression, to unzip the directory, command line execution of the direct Python setup.py install can be completed

Import Matplotlib again later or missing library: Dateutil

3, install Dateutil

Official website Download: https://pypi.python.org/pypi/python-dateutil/1.4.1

I downloaded the python-dateutil-2.3 source installation also to the decompression directory, execute Python setup.py install can also be installed successfully,

Continue execution: import matplotlib; still error: Missing pyparsing library

4, install pyparsing

official website Download http://pyparsing.wikispaces.com/Download+and+Installation
Installation method and the same as before decompression, direct python setup.py install, installation complete = =
Still import matplotlib, still missing: NumPy:

5, install NumPy

Download http://www.numpy.org/

I directly download the NumPy 1.9.1, the old way to install, the results in the installation, the error:

First encounter this error, after searching the data on the Internet, found that its own C++/C compiler VC Setup problem,

First go to the Python directory and find the lib-->distutilsmsvc9compiler.py file:

Need to be modified:

Query_vcvarsall (VERSION, Plat_spec)

This line, if you install VS2012, change version directly to 11.0 if VS2013 is changed to 12.0

After that, you find:

Mfinfo = Self.manifest_get_embed_info (Target_desc, Ld_args)

This line, change directly to:

Mfinfo = None

Execute the python setup.py install again NumPy success:

Execute import matplotlib ok! again

A running result:

Python installation matplotlib,six,dateutil,pyparsing complete process
