Python Django Mezzanine安装Pillow包失败

Question

我在尝试安装Mezzanine的时候，结果在安装Pillow时失败了。

运行python setup.py install时出现了这个错误：

如果我用pip install mezzanine来安装，就会出现这个错误：

Traceback (most recent call last):
File "/home/franco/.virtualenvs/audace/bin/pip", line 11, in <module>
sys.exit(main())
File "/home/franco/.virtualenvs/audace/local/lib/python2.7/site-packages/pip/__init__.py", line 185, in main
return command.main(cmd_args)

text = '\n'.join(complete_log)
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 28: ordinal not in range(128)

可以看到，问题出在安装Pillow的要求上。我是在使用虚拟环境（virtualenv）。

谢谢！

按照上面的说明去安装开发库。在第二个命令中，把第一个“libjpeg”删掉，变成这样：

    sudo apt-get install libjpeg-dev libfreetype6 libfreetype6-dev zlib1g-dev

然后，安装pillow就可以了！

Answer 2

你需要安装开发库。在Ubuntu系统上，这意味着你需要执行以下操作：

sudo apt-get install python-dev build-essential 
sudo apt-get install libjpeg libjpeg-dev libfreetype6 libfreetype6-dev zlib1g-dev
sudo apt-get build-dep python-imaging

这个问题在12天前已经修复了，所以你可能想运行 pip install -U pillow，或者 pip install git+https://github.com/python-pillow/Pillow.git 来更新。
