Re: [Jython-dev] Pip on Windows

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

I just tested with respect to Jython trunk, and pip now does work as
expected. I believe this is the result of an accumulation of small
compliance changes for Windows that Stefan and others have recently made,
so this is really great!

So on Windows we have the following:

C:\Users\jimba>c:\jython2.7.1-rc1-A\bin\pip install yolk
Collecting yolk
  Downloading yolk-0.4.3.tar.gz (86kB)
 [K    100% |################################| 92kB 100kB/s ta 0:00:01
 [?25hRequirement already satisfied: setuptools in
c:\jython2.7.1-rc1-a\lib\site-packages (from yolk)
Installing collected packages: yolk
  Running setup.py install for yolk ...  [?25ldone
 [?25hSuccessfully installed yolk-0.4.3

C:\Users\jimba>c:\jython2.7.1-rc1-A\bin\yolk.exe --list
pip 9.0.1 has no metadata
pytz 2016.10 has no metadata
setuptools 28.8.0 has no metadata
wsgiref         - 0.1.2        - active development (c:\jython2.7.1-rc1-a\lib)
yolk            - 0.4.3        - active

So ignoring some wrong for Windows terminal escape usage (presumably pip,
or a vendored library it uses, assumes it's not running on Windows), this
pip install works really well: it properly installs yolk, which is an exe
that wraps Python (via the complex magic that's roughly equivalent to #! on
Windows); and this yolk executable in turn is able to introspect the Jython
installation to list installed packages.

Note that we also bundle pip 9.0.1, which is the latest version. (Hurry,
let's ship Jython 2.7.1 quick before an updated pip breaks on Jython,
again! :)

Given that the pip bug (http://bugs.jython.org/issue2521) was the only
*remaining blocker* for 2.7.1, we should be ready to  for a release
candidate. We may want to address some other problems in our bug list, but
if so, this means updating the bug's priority/milestone accordingly.

Thanks again for the great work!

- Jim
