[Bug 1290847] Re: pyvenv fails due to mising ensurepip module

[Barry Warsaw]

If I'm reading the rewheel code correctly, I think we are going to have
to do something like the following:

* Package up wheel for Debian (python-wheel, and python3-wheel).  This
gives us the setuptools bdist_wheel command.

* At Python build-time we need *.dist-info/RECORD files for setuptools,
pip, and recursively vendored packages.  We do not currently generate
these, and there's a bit of a bootstrapping problem.  But let's say for
the moment we can generate all these dist-info directories, we need to
put them some place where the python3.4 debian/rules can find it
*without* downloading anything from PyPI.  My thought is that we
bootstrap this by building setuptools-wheel, pip-wheel, etc binary
packages which only contain the dist-info/ directories.  We can then
build-dep python3.4 on those *-wheel packages.

* We need to package up rewheel too, both in PyPI and Debian.  It'll
take a little work to whip the code in shape, but it's not too bad I
guess.  I really don't like patching Python the way rewheel does it, so
I'll look at alternatives.  Hopefully bkadrda will accept pull requests.

Anyway, that's a general plan, and the devil is in the details, but I
think I see how it all hangs together.

  Hello,

  I noticed the following

  # fails
  python3.4 -m venv --clear python-venv
  Error: Command '['.../external/python-venv/bin/python3.4', '-Im', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1

  # works, but no pip
  python3.4 -m venv --clear --without-pip python-venv

  Thank you
