Pip version virtualenv doesn't match and won't upgrade

Okay, so, I run my project packages in a virtual environment. I usually manage these packages through PyCharm. PyCharm tells me I have Pip 9.0.1 installed. Only when I run my virtual environment from the command line and I print pip version, it says 7.1.0. If I try upgrading using pip install --upgrade pip I get an error

Collecting pip

Installing collected packages: pip
  Found existing installation: pip 7.1.0
    Uninstalling pip-7.1.0:

AttributeError: 'NoneType' object has no attribute 'bytes'

My system-wide pip version is 9.0.1 though. I just don't get what is happening. Hopefully someone can shed some light. I've tried de-installing and re-installing it again, I've tried using a wheel to install, doesn't work

Windows, by the way.

Open the Command Prompt (cmd) as administrator and run:

pip install --user --upgrade pip

Or try:

python -m pip install --user --upgrade pip

Relevant GitHub issue.

I had the same issue, but found the answer here: https://github.com/pypa/pip/issues/2669

Basicly I just had to use this command instead: easy_install -U pip
