About the PIL Error -- IOError: decoder zip not available

提问by DevX

I am getting the:

我得到：

IOError: decoder zip not available

when I try to draw an image and save to a jpeg in PIL. Any thoughts on how to resolve this? PIL has worked fine for me in the past, when it comes to viewing/uploading images.

当我尝试绘制图像并保存到 PIL 中的 jpeg 时。关于如何解决这个问题的任何想法？过去，在查看/上传图像时，PIL 对我来说效果很好。

It likely only needs the zip decoder to save the jpeg. I think I needed to follow these steps in OS X to preview jpegs.

它可能只需要 zip 解码器来保存 jpeg。我想我需要在 OS X 中按照这些步骤来预览 jpeg。

It probably means you need to:

这可能意味着您需要：

• Download the PIL source.
• Download the zlib library.
• Point the PIL source to the zlib library.
• Build PIL.

• 下载PIL 源代码。
• 下载 zlib 库。
• 将 PIL 源指向 zlib 库。
• 构建 PIL。

The more detail installation PIL with zlib library in Ubuntu 64 bit :

在 64 位 Ubuntu 中使用 zlib 库的更详细的安装 PIL：

sudo pip uninstall PIL
sudo pip install pillow 

^^ fixed it for me.

^^ 为我修好了。

Pillowis a fork of PIL that is compatible with pip/setuptools and gets a little better maintenance. I haven't seen any API differences yet.

Pillow是 PIL 的一个分支，它与 pip/setuptools 兼容并且得到了更好的维护。我还没有看到任何 API 差异。

Edit: There is one notable API difference. PIL exposes Image as a top-level namespace, so you can

编辑：有一个显着的 API 差异。PIL 将 Image 作为顶级命名空间公开，因此您可以

import Image # in PIL only

but

但

from PIL import Image  # in pillow or PIL

I encountered this problem on a 64bit ubuntu 13.04 desktop versionand here is how I resolved it.

我在64 位 ubuntu 13.04 桌面版本上遇到了这个问题，这是我解决的方法。

try to reinstall PIL, and pay attention to the output info after you reinstalled:

尝试重新安装PIL，并注意重新安装后的输出信息：

---------------------------------------------------------------------
PIL 1.1.7 SETUP SUMMARY
--------------------------------------------------------------------
version       1.1.7
platform      linux2 2.7.4 (default, Sep 26 2013, 03:20:26)
              [GCC 4.7.3]
--------------------------------------------------------------------
*** TKINTER support not available
--- JPEG support available
*** ZLIB (PNG/ZIP) support not available
--- FREETYPE2 support available
*** LITTLECMS support not available
--------------------------------------------------------------------

notice that there is a line :*** ZLIB (PNG/ZIP) support not available, which means PIL have been built without ZLIB support, and I fixed it by doing this:

注意有一行 : *** ZLIB (PNG/ZIP) support not available，这意味着 PIL 是在没有 ZLIB 支持的情况下构建的，我通过这样做修复了它：

first you should have these packages install: libjpeg-dev libfreetype6-dev zlib1g-dev

首先你应该安装这些包：libjpeg-dev libfreetype6-dev zlib1g-dev

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

# create these links, if already exists, remove it and re-link it
ln -s /usr/lib/x86_64-linux-gnu/libjpeg.so /usr/lib
ln -s /usr/lib/x86_64-linux-gnu/libfreetype.so /usr/lib
ln -s /usr/lib/x86_64-linux-gnu/libz.so /usr/lib

# reinstall PIL
pip uninstall PIL
pip install PIL

This time, there should be a line --- ZLIB (PNG/ZIP) support availablein the output.

这一次，--- ZLIB (PNG/ZIP) support available输出中应该有一行。

I encountered same problem. It seems to me that Pillow and pillow (different case in 'p') are two different packages. So, if you are using Pillow, pip install pillowmight not help. Here is my solution:

我遇到了同样的问题。在我看来，枕头和枕头（'p' 中的大小写不同）是两个不同的包。因此，如果您使用 Pillow，pip install pillow可能无济于事。这是我的解决方案：

$ pip uninstall pillow
$ pip uninstall Pillow
$ sudo apt-get install libjpeg-dev zlib1g-dev
$ pip install -I Pillow

First two lines are to remove any pillow or Pillow package.

前两行是删除任何枕头或枕头包。

Third line is to install the two required packages.

第三行是安装两个需要的包。

Forth is re-install Pillow.

第四是重新安装 Pillow。

Note, if you are using virtualenv, pip install/uninstallmust be run under virtualenv

注意，如果你使用的是virtualenv，pip install/uninstall必须在virtualenv下运行
