I am trying to install some python packages but I am getting this kind of error every time.

Exception:

I looked it up on this site and Stack Overflow and all the solutions suggest installing

wheel

or

setuptools

But I am getting

Requirement already satisfied

The same problem occurs for trying to upgrade python packages. What should I do?

    1. What commands you were using to install these Python packages? 2. Can you do pip --version and tell us what version of pip you are using?

  • One of the many commands I used that gave me error was: pip install -U textblob and the pip version is: pip 8.1.1 from /usr/lib/python2.7/dist-packages (python 2.7)

I would try to install and update python packages using sudo As an example:

sudo pip install --upgrade pandas

or

sudo python -m pip install --upgrade pandas

I am using Ubuntu 16.04 gnome and it works fine and it also worked fine before I upgraded, means on ubuntu 14.04. Maybe you can also try to upgrade pip itself using

sudo pip install --upgrade pip

Hope it helps.

  • Have also a look here. The lowes answer, where you use wget to install an alternative pip might be the right answer.
