Try installing on a non Unicode path

Likely the same underlying bug as #2294

This is not a problem of unicode path.
time.strftim('%c') produce unicode string.
jythontools/pip attempt to write it to logfile.

See here
https://github.com/jythontools/pip/blob/develop/pip/basecommand.py#L207

FYI, CPython2's time.strftime('%c') produces byte string, not unicode.

>>> import time
>>> time.strftime('%c')
'Sun Mar 29 14:54:48 2015'
>>> import locale
>>> locale.setlocale(locale.LC_ALL, '')
'ja_JP.UTF-8'
>>> time.strftime('%c')

Naoki, thanks for the pointing out the problem with time.strftime and that causing the logging itself to fail, that's very helpful!

Are you able to use ensurepip then from the command line like so:

$ LC_ALL=C jython -m ensurepip

LC_ALL=C doesn't affect on Mac.
After changing system language to English from system configuration, I can run ensurepip.

Fixed as of https://hg.python.org/jython/rev/c06821df7422

Naoki, Please try the first build of RC2 - http://sourceforge.net/p/jython/mailman/message/33715614/ - and see if this resolves the issue. Thanks!

Success! Thank you.
