ubuntu 14.04, pip cannot upgrade matplotllib

Question

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

Why did it fail? Many thanks!

It might be helpful if You tell us what OS You are using and the exact pip command You issued. — Adobe, Sep 05 '14 at 09:12
I said it in the title. Ubuntu 14.04. But, anyway, the answer below helped me. Thank you so much! :-) — astroboylrx, Sep 07 '14 at 17:53

This is a known bug that has been fixed (https://github.com/matplotlib/matplotlib/pull/3414) on master.

The bug is in the handling of searching for a freetype installation. If you install the Linux package freetype-dev, you will avoid this bug and be able to compile matplotlib.

sudo apt-get install libfreetype6-dev

Is `freetype6-dev` (and perhaps `libxft-dev` for Ubuntu 14 server) installed with `apt-get build-dep python-matplotlib`? – drevicko Mar 29 '15 at 10:06

I can confirm this applies to Ubuntu 16.04 too and the indicated solution works. – h7r Jul 21 '16 at 06:55

@Vanuan, thank you. I can confirm on Ubuntu 16.04, using Python 2.7, that installing libfreetype6-dev as worked as a workaround. Appreciate it. – AgnosticDev Aug 14 '16 at 03:59
needed to install libxft-dev also. – sarvajeetsuman Jul 28 '17 at 18:09
Thank!! works for me in Ubuntu 14.04 and python3 with the command "apt-get build-dep python3-matplotlib" – henryr Sep 22 '17 at 19:13
Thank you so much, this finally allowed me to install matplotlib on a ReSpeaker Core v2.0. – SomeDude Mar 03 '19 at 22:17

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

sudo apt-get install libfreetype6-dev libxft-dev

It seems very difficult to make out what needs to be done. However, it looks like on Ubuntu 14 sudo apt-get install libfreetype6-dev libxft-dev followed by sudo pip install matplotlib WORKS !! – Somum Feb 10 '16 at 04:52
This is also required for Bash on Windows 10. – Ninjakannon Oct 29 '16 at 14:55

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.

In Ubuntu 15.04, this wants to install 419 packages totaling 1 GB. – knite May 28 '15 at 07:06
@knite That is tradeoff between manual dependency management and convenience. – tchakravarty Apr 17 '16 at 16:40

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

I also had to install `pkg-config` with `brew install pkg-config` and then it worked. – user3148185 Nov 05 '15 at 00:09

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.

While this code snippet may solve the question, [including an explanation](//meta.stackexchange.com/questions/114762/explaining-entirely-code-based-answers) really helps to improve the quality of your post. Remember that you are answering the question for readers in the future, and those people might not know the reasons for your code suggestion. Please also try not to crowd your code with explanatory comments, this reduces the readability of both the code and the explanations! – kayess Dec 12 '16 at 11:17

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

sudo dnf install freetype-devel gcc-c++

This worked for me:

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