[pypy-issue] [issue1272] user and home install schemes broke in pypy

[Carl Meyer]

Carl Meyer <carl at oddbird.net> added the comment:

Conclusions from discussion on IRC today:

1) In the long term, it would be good for PyPy to emulate CPython layout more
closely and eliminate the special PyPy distutils install scheme.

2) In the short term, because virtualenv already hardcodes the PyPy scheme, this
change would break use of PyPy with existing virtualenv releases.

3) It might be possible to make the scheme transition in future without a hard
break if virtualenv first implements
https://github.com/pypa/virtualenv/issues/416, and versions of virtualenv using
get_python_lib gain wide traction.

In the very short term (for the PyPy 2.0 release), the attached patch at least
fixes the "home" and "user" schemes, without making any changes to the default
use of pypy scheme.

This does not yet fix virtualenv issues 302 and 306 (or pip 625), but it does
fix pip issues 624 and 629.
