Answer 1

添加JPEG支持枕頭，在Ubuntu，你可以做到以下幾點：

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

# Link the libraries for Pillow to find them: 

sudo ln -s /usr/lib/`uname -i`-linux-gnu/libfreetype.so /usr/lib/ 
sudo ln -s /usr/lib/`uname -i`-linux-gnu/libjpeg.so /usr/lib/ 
sudo ln -s /usr/lib/`uname -i`-linux-gnu/libz.so /usr/lib/ 

# reinstall Pillow (In case you have Pillow already installed) 
pip install --upgrade --force-reinstall pillow 

Answer 2

我面對下我BitNami LAMP虛擬機同樣的問題，不能從連接丟失的文件解決了它枕頭。最後，我解決了這個問題：

第一，找到的lib

(venv)...$ find 2>/dev/null/-name libz.so 
/opt/bitnami/common/lib/libz.so 

現在加上lib目錄到點子

(venv)...$ pip install --global-option=build_ext --global-option="-L/opt/bitnami/common/lib" --global-option="-I/opt/bitnami/common/include" --upgrade --force-reinstall pillow 

它的工作原理：

-------------------------------------------------------------------- 
PIL SETUP SUMMARY 
-------------------------------------------------------------------- 
version  Pillow 2.7.0 
platform  linux2 2.7.6 (default, Mar 22 2014, 22:59:56) 
      [GCC 4.8.2] 
-------------------------------------------------------------------- 
*** TKINTER support not available 
--- JPEG support available 
*** OPENJPEG (JPEG2000) support not available 
--- ZLIB (PNG/ZIP) support available 
--- LIBTIFF support available 
--- FREETYPE2 support available 
*** LITTLECMS2 support not available 
*** WEBP support not available 
*** WEBPMUX support not available 
-------------------------------------------------------------------- 

也看到python pip specify a library directory and an include directory

安裝必需的庫：

http://pillow.readthedocs.org/en/latest/installation.html#linux-installation

然後卸載，並在您的virtualenv

pip uninstall Pillow 
pip install --no-cache-dir Pillow 

Answer 4

重裝枕頭其實，我發現這裏的選擇的解決方案是有很大的幫助。我還發現，djangcms安裝程序需要特定版本的Pillow，導致它無論如何都無法拾取JPEG模塊。在撰寫本文時，它想要Pillow==2.8.0，但pip --upgrade安裝的最新版本是2.9.x.我跑了pip install --no-cache-dir --upgrade --force-reinstall pillow==2.8.0，似乎滿足了djangocms安裝程序的要求，因此它會保持JPEG兼容性。

您可以通過在virtualenv中打開python shell來驗證是否安裝了JPEG支持。

from PIL import Image 

i = Image.open('/path/to/a.jpg') 
i.load() 

你要麼得到一個處理加載的圖像或異常，如果沒有JPEG的支持。

所以pip成功安裝了JPEG支持的Pillow軟件包，但只要我運行djangocms安裝程序，它就會用沒有JPEG支持的Pillow軟件包替換它。您需要匹配djangocms安裝程序所需的Pillow版本。我不知道配置在哪裏，但是在安裝失敗之後，您可以用pip freeze或pip list找出它。

希望這可以幫助別人。
