Package management

There seem to be several ways (tools) to manage Python packages. This time, refer to the contents here

Python package management technology summary (pip, setuptools, easy_install, etc) http://www.yunabe.jp/docs/python_package_management.html

Select ** pip **, which is considered to be the most modern as of December 2014.

pip ** Official documentation ** about installing

https://pip.pypa.io/en/stable/installing/

Articles explained in Japanese

How to use pip (2014/1 version) @ I'll write it somehow. http://tdoc.info/blog/2014/01/15/pip.html

In addition, it should be noted It seems that it is ** included ** in Python 2.7.9 or later. So, the version of Maya embedded Python will be upgraded soon, You will be able to use pip without doing anything.

As of Maya2016, mayapy is ** Python 2.7.6 **.

Installation

get-pip.py Download get-pip.py from the official documentation and Hit this in Python and you're done. As of 20160103, download from here> https://bootstrap.pypa.io/get-pip.py Or here too> https://raw.github.com/pypa/pip/master/contrib/get-pip.py

Here, instead of so-called Python, ** mayapy ** takes on that role. In other words

python get-pip.py ↓ mayapy get-pip.py

is.

Run

1. Right-click cmd and select "** Run as administrator **" to launch it.
2. Use cd to move to where mayapy is

result

There is a folder called ** "Python" ** under the Maya installation folder, It will be placed there with the following feelings.

• This is here

mayapy's PYTHON HOME

>>> import os
>>> os.environ['PYTHONHOME']
'C:\\Program Files\\Autodesk\\Maya2016\\Python'

Scripts folder

A ** "Scripts" ** folder will be created directly underneath. Related exes such as "easy_install.exe", "pip.exe" and "wheel.exe" are placed.

Lib > site-packages Various will be added. Difference between before and after execution. The right column is after. Light blue is a new item.

import pip You will be able to import pip with mayapy. It's a confirmation like "Oh, it's working".

Summary

With administrator privileges mayapy get-pip.py that's all.

This time I will "try to put it in", so the contents from here onwards will be on another occasion (?)

This is all you can do to pollute the environment. The formation of chaos is at your own risk! ←
