pip: pip 6.0.8 AttributeError when upgrading to 6.1.1 in virtualenv

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.

easy_install -U pip worked for me . Thanks 👍

sorry, --force-reinstall

I’m seeing this same problem trying to upgrade pip within a virtualenv that was created with pip 9.0.1 by PyCharm.

please note that easy_install -U pip has some dire consequences as it does an egg based install instead of a sane install

Yep, same. Windows 10. Python 2.7.10.

easy_install -U pip

The above command worked.

easy_install -U pip worked for me too . Thanks for all

I also faced this issue, when using Intellij IDEA to set up the virtualenv. Python: 3.6.3 Pip: 9.0.1 Intellij: 2018.1 (Ultimate Edition) 181.4203.550 Windows 7: 6.1

Running easy_install -U pip seemed to work for me. Not sure if @RonnyPfannschmidt’s warning is relevant as I don’t know what an “egg based install” is. It installed pip 10.0.0b2 and seems to be working fine.

Same here, using easy_install helped.

Win 10 and Python 3.4.4, same error, the pip force reinstall thing didn’t work but the easy_install -U pip did.
