pip 6.0.8 AttributeError when upgrading to 6.1.1 in virtualenv

See original GitHub issue

Windows 7, Python 3.4.3, updated pip in base. Created virtualenv, saw that it was still on pip 6.0.8

Activated venv, ran python -m pip install pip -U

log:

Installing collected packages: pip
  Found existing installation: pip 6.0.8
    Uninstalling pip-6.0.8:
      Successfully uninstalled pip-6.0.8

  Rolling back uninstall of pip
...
     result = finder(distlib_package).find(name).bytes
 AttributeError: 'NoneType' object has no attribute 'bytes'

However, next time I run pip -V, it reports pip 6.1.1, so what is the effect of the error?

Same sh** with pip 7.1.0 with Python 2.7 on Window 7 64bit - see below.

BUT HAPPILY easy_install -U pip did it for me and upgraded to 7.1.2 😃

H:\>pip install -U pip
You are using pip version 7.1.0, however version 7.1.2 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.
