ubuntu 14.04, pip cannot upgrade matplotllib

Question

When I try to upgrade my matplotlib using pip, it outputs:

Downloading/unpacking matplotlib from https://pypi.python         


        

Answer 1

I was trying too update directly using sudo pip but changes are not saved in last. So i first use update cmd in terminal:

sudo apt-get update

then i used sudo install:

sudo apt-get install libffi-dev

Finally its installed by doing this method.

Answer 2

This worked for me:

python -m pip install -U pip setuptools
python -m pip install matplotlib

For more details, follow : https://matplotlib.org/2.0.0/users/installing.html

Answer 3

I had the same issues trying to install matplotlib on Python 3 using pip3, and it seems that this problem is related to a bare-bones installation of Python 3, and doing a:

sudo apt-get build-dep matplotlib

followed by

sudo pip3 install matplotlib 

is probably a better solution than selectively installing only the libraries related to matplotlib.

Answer 4

On Ubuntu 14 server, you also need to install libxft-dev

sudo apt-get install libfreetype6-dev libxft-dev

Answer 5

Since mac doesn't have apt-get you, on OSX you may need to do:

brew install freetype

then you can run:

pip install matplotlib

Answer 6

For those on Fedora 25 hitting this thread, I needed these two packages to make it work:

sudo dnf install freetype-devel gcc-c++
