Installing matplotlib and its dependencies without

问题:

I want to use matplotlib on a server where I have an account /myhome without root privileges.

I downloaded the matplotlib sources and tried to install it using the distutils with the user sheme, say python setup.py install --user, but it returned the following message :

============================================================================
                    * The following required packages can not be built:
                    * freetype

It seemed that the package 'freetype' was missing, so I downloaded its sources, and I found that it could be installed in a specific place by running:

./configure --prefix=/myhome/somedir
make
make install

My question is: where do I install freetype so it can be detected by the distutils ?

My first thought was to install it in /myhome/.local because this is where the distutils install a module when using the --user option. Unfortunately, when doing this, I still got the same message as above.

I tried something more complicated by creating a virtual environment using the virtualenv package :

virtualenv /myhome/venv/

Then I installed freetype in myhome/venv/ and finally I ran the distutils within this virtual environnement, but it gave me the same message again.

Thank you for helping, and, of course, I won't ask my sysadmin to install matplotlib for me.

PS: something certainly unrelated with my problem but maybe worth noting : I install the freetype package by using ./configure --prefix=/myhome/somedir --without-png. Without the --without-png option, I get the following error:

checking for libpng... configure: error: `libpng-config' not found;
either set the LIBPNG_CFLAGS and LIBPNG_LDFLAGS environment variables,
or pass `--without-png' to the `configure' script.

Based on some suggestions here and other instructions on the internet, the following recipe worked for me:

 wget http://download.savannah.gnu.org/releases/freetype/freetype-2.5.3.tar.gz
 tar xzf freetype-2.5.3.tar.gz
 cd freetype-2.5.3
 ./configure --prefix=/myhome/local --without-png
 make && make install
 export PKG_CONFIG_PATH=/myhome/local/lib/pkgconfig
 pip install matplotlib --upgrade

回答2:

You should install system requirements, and it doesn't not related to python, pip, virtualenv.

To install the requirements, please refer this. https://stackoverflow.com/a/20533455/2962018

In a nutshell,

Ubuntu/Debian

apt-get install libfreetype6-dev

Redhat

yum -y install freetype-devel

OSX

brew install freetype

After installing freetype, try

pip install matplotlib

From what I can see, matplot setup will eventually call the prompt with

pkg-config freetype2 --modversion 

to try and find the package. It seems like it fails on this call.

Try to see what error that command gives you and let us know. See http://people.freedesktop.org/~dbn/pkg-config-guide.html for more info on pkg-config. It's possible on some systems that pkg-config is not installed.

UPDATE: From what I can get from the matplotlib setup files, it'll search for ft2build.h in subdirectories include, lib and lib64 in the directories /usr/local and in /usr.

You can find the needed source files for freetype at http://www.freetype.org/developer.html (you'll need the .h files, but it won't hurt to get all of them).

In case you don't have access to any of these directories, you can add directories for it to search in by editing the directories entry in setup.cfg for matplotlib.

Should you not be able to edit the setup.cfg file, you can also try to edit the setupext.py file in your matplotlib directory directly. In line 95, there is a function get_base_dirs, you could edit this function to return extra directories for it to search in (it'll look for subdirectories include, lib and lib64 in those added directories).

May be very late now, but I just faced same issue while installing matplotlib inside virtualenv created using virtualenvwrapper.

These instructions worked for me: http://newcoder.io/dataviz/part-0/

回答5:

Specifically for mac: I had similar issue in installing the matplotlib. Follow these instructions and you are done:

1. Install python3 using brew. ( Ignore this step if you already have it) Note: To install brew.

   brew install python3
   

2. Install freetype :

   brew install freetype
   

3. Now install pkg-config using pip3:

   brew install pkg-confi
   

4. Finally install matplotlib:

   sudo pip3 install matplotlib
   

回答6:

I had got the same error while installing matplotlib. Installing pkg-config worked for me. Try the following command for ubuntu:

sudo apt-get install pkg-config
