Pip install Matplotlib error with virtualenv

Question

I am trying to install matplotlib in a new virtualenv.

When I do:

pip install matplotlib

or

pip install http://sourceforge.net/projects/matplotlib/files/matplotlib/matplotlib-1.1.0/matplotlib-1.1.0.tar.gz

I get this error:

building 'matplotlib._png' extension

gcc -pthread -fno-strict-aliasing -DNDEBUG -g -fwrapv -O2 -Wall -fPIC -  DPY_ARRAY_UNIQUE_SYMBOL=MPL_ARRAY_API -DPYCXX_ISO_CPP_LIB=1 -I/usr/local/include -I/usr/include -I. -I/home/sam/django-projects/datazone/local/lib/python2.7/site-packages/numpy/core/include -I. -I/usr/include/python2.7 -c src/_png.cpp -o build/temp.linux-x86_64-2.7/src/_png.o

src/_png.cpp:10:20: fatal error: png.h: No such file or directory

compilation terminated.

error: command 'gcc' failed with exit status 1

Anyone have an idea what is going on?

Any help much appreciated.

You may also see `The following required packages can not be built: freetype, png` which is the same error in (I think) a newer version of `pip`. — LondonRob, Jul 27 '15 at 17:06

Building Matplotlib requires libpng (and freetype, as well) which isn't a python library, so pip doesn't handle installing it (or freetype).

You'll need to install something along the lines of libpng-devel and freetype-devel (or whatever the equivalent is for your OS).

See the building requirements/instructions for matplotlib.

Thanks for the info! I finally got it working by installing the following dependencies in ubuntu: `libpng-dev`, `libjpeg8-dev`, `libfreetype6-dev`. – Darwin Tech Mar 26 '12 at 15:26

`sudo apt-get build-dep python-matplotlib` also does the trick! – william_grisaitis Feb 04 '13 at 00:59

It may work, but note that it wants to install quite a few packages (more than can fit in this comment box), but about 0.6 GB worth of packages. – Achal Dave Feb 15 '14 at 23:32

On my debian (wheezy/unstable) system it was failing even with `libfreetype6-dev` installed. It turned out that I also needed `pkg-config` installed. – Jon Mar 05 '14 at 20:25
I actually have libfreetype6-dev intalled on ubuntu 14.04. Matplotlib seems not to be picking it. – tutuca Aug 06 '14 at 04:19
Also check the versions you have installed are the ones stated in the requirements. I already had png (libpng) and freetype installed and "yum" said that they were already at the latest version. However, the version was still lower than the requirements so I had to go to the package's website and install by hand. That fixed it for me. – mirandes Sep 24 '14 at 11:58

To generate graph in png format you need to Install following dependent packages

sudo apt-get install libpng-dev
sudo apt-get install libfreetype6-dev

Ubuntu https://apps.ubuntu.com/cat/applications/libpng12-0/ or using following command

sudo apt-get install libpng12-0

As I have struggled with this issue twice (even after fresh kubuntu 15.04 install) and installing freetype did not solve anything, I investigated further.

The solution:
From github issue:

This bug only occurs if pkg-config is not installed;
a simple
sudo apt-get install pkg-config
will shore up the include paths for now.

After this installation proceeds smoothly.

Same here. pip install matplotlib gave me error: `IMPORTANT WARNING: pkg-config is not installed. matplotlib may not be able to find some of its dependencies.` Freetype shows not installed. I just did `brew install pkg-config` and was able to get by. – Lily Jan 18 '16 at 01:45
This is also the problem on Bash on Ubuntu on Windows Insider Preview – Jens de Bruijn Jun 11 '16 at 13:27

As a supplementary, on Amazon EC2, what I need to do is:

sudo yum install freetype-devel
sudo yum install libpng-devel
sudo pip install matplotlib

It is recommended to install a package to a virtual environment, which makes `pip` so nice. Hence `sudo pip install` negates most of the usefulness that pip brings to the table. – Roman May 14 '15 at 06:48

On OSX I was able to get matplotlib to install via:

pip install matplotlib==1.4.0

only after I ran:

brew install freetype

Under Windows this worked for me:

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

I needed `sudo apt-get install pkg-config` first though. – jpcgt May 10 '16 at 18:52

None of the above answers worked for me in Mint, so I did:

sudo apt-get install build-essential g++

If on MacOSx try

xcode-select --install

This complies subprocess 32, the reason for the failure.

To reduce the required packages to install you just need

apt-get install -y \
    libfreetype6-dev \
    libxft-dev && \
    pip install matplotlib

and you will get the following packages locally installed

Another option is to install anaconda, which comes with packages such as: Matplotlib, numpy and pandas.
