PIL in Ubuntu 14.04-优快云博客

本文提供了一个详细的指南，教你如何在Ubuntu 14.04上安装Python Imaging Library (PIL)。文章首先介绍了确保安装所需的库的方法，然后提供了具体的步骤来解决安装过程中遇到的常见问题。

With pillow Replacing PIL it has no more been much Widely Used.

Still if in any cases you want to install PIL then here goes the tutorial if you failed trying installing pip via

pip install PIL

http://www.pythonware.com/products/pil/
python setup.py install

First make sure you have following libraries

sudo apt-get build-dep python-imaging sudo apt-get install libjpeg62 libjpeg62-dev

And try there installing via pip install PIL.

if it continues to fail, it can be due to PIL searching those libraries in a different path.

It turns out that the APT installations put the libraries under /usr/lib/x86_64-linux-gnu and PIL will search for them in /usr/lib/. So you have to create symlinks for PIL to see them.

Try to see if libjpeg and libz libs exist in /usr/lib/x86_64-linux-gnu and make a symlink this way

32-bit version

sudo ln -s /usr/lib/i386-linux-gnu/libz.so /usr/lib/libz.so sudo ln -s /usr/lib/i386-linux-gnu/libjpeg.so /usr/lib/libjpeg.so sudo ln -s /usr/lib/i386-linux-gnu/libfreetype.so /usr/lib/libfreetype.so

64-bit version

sudo ln -s /usr/lib/x86_64-linux-gnu/libz.so /usr/lib/libz.so sudo ln -s /usr/lib/x86_64-linux-gnu/libjpeg.so /usr/lib/libjpeg.so sudo ln -s /usr/lib/x86_64-linux-gnu/libfreetype.so /usr/lib/libfreetype.so
