В Ubuntu 16.04, когда вы делаете:
pip install --upgrade pip
Вы получаете:
Collecting pip
Using cached pip-8.1.2-py2.py3-none-any.whl
Installing collected packages: pip
Successfully installed pip-8.1.1
You are using pip version 8.1.1, however version 8.1.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
Справедливо. Сейчас попробуй
pip install --upgrade pip
и вы получите:
Collecting pip
Using cached pip-8.1.2-py2.py3-none-any.whl
Installing collected packages: pip
Successfully installed pip-8.1.1
You are using pip version 8.1.1, however version 8.1.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
Итак, как на самом деле получить пипс 8.1.2?
sudo -H pip install --upgrade pip
