【问题描述】：

我在 django cms 2.3.3 上进行本地安装时遇到问题：我已经通过 pip 在单独的 virtualenv 中安装了它。接下来我按照 settings.py 配置的教程，我启动了服务器。然后在管理员中我创建了一个页面（主页），我尝试通过 cmsplugin_filer_image 在占位符中添加一个图像，但上传似乎不起作用。这是我的设置.py：

当我尝试上传图片时，在剪贴板部分我没有缩略图，只有一条“未定义”消息：

这是尝试上传时的运行服务器控制台：

因此文件已上传，但 cms 无法访问它们。这里有一个similar question，但对我帮助不大。 在这个问题上对我有任何帮助都会非常有帮助。

谢谢，卢克

【参考方案1】：

此错误是因为您安装了不支持 JPEG/PNG 的 PIL。 您将需要安装以下软件包

sudo apt-get install python-imaging  python-dev libjpeg8 libjpeg8-dev libfreetype6 libfreetype6-dev

然后卸载PIL pip uninstall PIL

我建议使用pip install pillow 安装枕头而不是 PIL。 安装后请务必阅读日志，应该说支持JPEG和PNG

【讨论】：

我已经安装了枕头而不是 PIL，我很确定我也通过 apt-get 安装了这些库。我必须检查哪个日志（我正在使用本地开发运行服务器）？

我的意思是使用 pip 安装枕头时控制台中显示的日志您应该看到类似 *** TKINTER support not available (Tcl/Tk 8.5 libraries required) --- JPEG support available --- ZLIB (PNG/ZIP) 支持 --- FREETYPE2 支持 --- LITTLECMS 支持

你使用的是什么 django-filer 版本？

谢谢，我不得不卸载并重新安装枕头，然后使用您提到的其他库正常工作。

如果你在 Windows 上使用 easy_install 枕头，pip 会安装但不会工作

【参考方案2】：

对我来说同样的问题 - 我同时安装了 PIL 和 Pillow，当两者都加载时会出现问题，但仅在某些虚拟机上。我发现在我的本地开发 Mac 和本地 Virtualbox CentOS VM 上一切正常，但错误发生在 Amazon CentOS 64 位机器上。我无法让它在所有三个上都与 Pillow 一起使用（使用 Pillow 2.2.2 和 PIL 1.1.7）。

我从 requirements.txt 中删除了 Pillow，而只使用了 PIL。我首先使用这个厨师食谱来安装 PIL，这在所有亚马逊和所有经过测试的盒子上都运行良好：

#!/usr/bin/env bash
sudo apt-get build-dep python-imaging
sudo ln -s -f /usr/lib/`uname -i`-linux-gnu/libfreetype.so /usr/lib/
sudo ln -s -f /usr/lib/`uname -i`-linux-gnu/libjpeg.so /usr/lib/
sudo ln -s -f /usr/lib/`uname -i`-linux-gnu/libz.so /usr/lib/

【参考方案3】：

*** 时间空间中的“老”问题，但我遇到了完全相同的问题。

bazaretas 为我指明了正确的方向，但我在设置中遗漏了一点。

我安装了 Pillow 而不是 PIL，但我的其他需求包之一依赖于 PIL（在其 setup.py 中），因此 pip 也安装了 PIL。但是 PIL 在分发和 virtualenv 上有问题，所以它没有抓住开发包来支持所有格式。

对我来说，被指控的包裹是 xhtml2pdf。

检查您的依赖关系或找到一种方法在您的 venv 中预先安装 PIL（即 here、here 或 there）。
