Replace easy_install and eggs with pip and wheels

[anonymous]

The Trac documentation talks a lot about easy_install and eggs. Presumably when it was written these were the best practices. It seems today using pip and wheels would be much easier and generally preferable.

The ​Python docs say:

pip is the preferred installer program. Starting with Python 2.7.9, it is included by default with the Python binary installers.

But from the Trac documentation (to someone who is not a Python packaging expert) it is far from clear if this is recommended or even possible with Trac. Some examples:

• TracInstall lists easy_install before pip, and the pip section is fairly confusing and assumes Linux, Apache, non-SQLite. This page does not mention wheels (the word egg appears six times).
• TracUpgrade does not mention pip or wheels at all. (easy_install is mentioned four times, egg once.)
• TracPlugins lists easy_install before pip, and much more often (12 vs. 5). This page does not mention wheels, while the word egg occurs >40 times.
• TracDev/PluginDevelopment: egg 10, wheel 0. Links to ​th:wiki:EggCookingTutorial as the tutorial to build plugins.

(And there are many more on other wiki pages.)

Please clarify if this is still the preferred way or just a historical relict nobody has bothered to change yet. Are pip and/or wheels supported and/or even preferred nowadays? Should such old documentation be updated to recommend pip first? Can old easy_install cruft even be removed?
