在 Ubuntu 14.04.1 LTS 中安装 PIL

Question

按照步骤如何安装 python 图像库 (PIL)？用于在 Ubuntu 14.04 上安装 PIL 的预设置库。但是，当我运行时pip install PIL --allow-external PIL --allow-unverified PIL看到以下错误：

building '_imagingft' extension

我已经使用这些命令成功安装了 PIL：

sudo apt-get build-dep python-imaging
sudo apt-get install libjpeg8 libjpeg62-dev libfreetype6 libfreetype6-dev
sudo pip install Pillow

在这些命令之后，我可以：

>>> import PIL
>>> PIL.VERSION
'1.1.7'
