Without this patch `virtualenv --python=python2.7 .` fails with an
|
|
error because it notices that the python readline.so is not in the
|
|
same path as python2.7. I assume this is to avoid copying the wrong
|
|
file on systems where it is possible to find incompatible libraries by
|
|
accident. Adding "/nix/store" to the prefix fixes this problem.
|
|
|
|
A sitecustomize.py is created in the virtualenv which makes libraries
|
|
from the python specified by the --python argument available to the
|
|
virtualenv. For example, this makes readline and sqlite3 available
|
|
when a wrapped python is specified. If no --python argument is passed,
|
|
it will only add the path to the python used when building
|
|
`virtualenv`, which is the unwrapped python, so sqlite3 won't be
|
|
available.
