我正在尝试使用 Python 2.7.8 在 CentOS 6.5 上安装 matplotlib-1.4.0。我试过用 pip 和从源代码安装。我最初收到一条错误消息，指出我需要更新版本的 Freetype2，然后我将其安装(版本 2.5.3)到/usr/local/bin、/usr/local/include 和/usr/local/lib。旧版本的 Freetype2 (2.3.11) 位于/usr/bin、/usr/include/freetype2/freetype 和/usr/lib 中。
现在，当我尝试安装 matplotlib (python setup.py build) 时，看起来包含路径都指向错误的(旧)版本的 Freetype2，我不知道如何更改适当的路径以指向较新的Freetype2 的版本。实际的错误消息在下面，而且非常困惑。我在网上找不到太多关于他的错误的信息，但我可以看到错误的 Freetype2 路径，所以我猜这就是导致问题的原因。有小费吗？
在其他线程上找到了有关添加/usr/include/freetype 符号链接(symbolic link)以指向/usr/local/include/freetype2 的提示，但这没有帮助。

最佳答案
虽然我使用的是 python-2.6，但我只是通过完全相同的 freetype 错误找到了一种方法:基本上你可以简单地下载 matplotlib python 存档并将 freetype-2.4 的要求编辑为 freetype-2.3。这一切都是在 virtualenv 中自然完成的。
pip 安装 --download 。 matplotlib==1.4.0
tar -xzvf matplotlib-1.4.0.tar.gz
vi matplotlib-1.4.0/setupext.py
min_version='2.4', version=version)
tar -czvf matplotlib-1.4.0.tar.gz
pip 安装 numpy
pip 安装 geojson==1.0.6
pip install --verbose matplotlib-1.4.0.tar.gz
