ubuntu 14.04，pip无法升级matplotllib

Question

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

Why did it fail? Many thanks!

Answer 1

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

Answer 2

在Ubuntu 14服务器上，您还需要安装libxft-dev

sudo apt-get install libfreetype6-dev libxft-dev

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

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 5

Found this page while looking answer for fedora 24.

RPM solution is:

dnf install freetype-devel

Answer 6

If you re running Ubuntu server 14.04 u should add this font dependency

sudo apt-get install libxft-dev

Source

Answer 7

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 8

对于使用Fedora 25的用户，我需要以下两个软件包才能使其正常工作：

sudo dnf install freetype-devel gcc-c++

Answer 9

This worked for me:

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