您必须重新安装PIL，还必须安装所需的库并手动链接它们。该答案基于此博客文章中的常规ubuntu PIL安装以及这个askubuntu问题，其中解释了如何编译jpeg编码：
### uninstall PIL
sudo pip uninstall pil
### download and compile the JPEG library
wget http://www.ijg.org/files/jpegsrc.v8c.tar.gz
tar xvfz jpegsrc.v8c.tar.gz
cd jpeg-8c
./configure --enable-shared --prefix=$CONfigURE_PREFIX
make
sudo make install
### link the libraries correctly - RASPBerry PI ONLY
sudo ln -s /usr/lib/arm-linux-gnueabi/libjpeg.so /usr/lib
sudo ln -s /usr/lib/arm-linux-gnueabi/libfreetype.so /usr/lib
sudo ln -s /usr/lib/arm-linux-gnueabi/libz.so /usr/lib
### install rest of the libraries, as well as freetrype and zlib
sudo apt-get install libjpeg-dev libfreetype6 libfreetype6-dev zlib1g-dev
### re-install PIL
sudo pip install pil
