Python PIL无法找到我的"libjpeg" [英] Python PIL cannot locate my "libjpeg"

问题描述

我无法使用PIL，因为它找不到我的libjpeg！

I cannot use PIL because it cannot find my libjpeg!

首先，我安装了默认PIL.当我运行selftest.py时，它给了我:

First, I installed PIL default. And when I ran the selftest.py, it gave me:

IOError: decoder jpeg not available 1
items had failures:    1 of  57 in
selftest.testimage
***Test Failed*** 1 failures.
*** 1 tests of 57 failed.

然后，我按照在线说明将PIL的setup.py更改为

Then, I followed instructions online to change PIL's setup.py to

JPEG_ROOT = "/usr/lib"

因为当我locate libjpeg时，这就是我得到的:

Because when I locate libjpeg, this is what I get:

locate libjpeg 
/usr/lib/libjpeg.so.62
/usr/lib/libjpeg.so.62.0.0
/usr/lib64/libjpeg.so.62
/usr/lib64/libjpeg.so.62.0.0
/usr/share/doc/libjpeg-6b
/usr/share/doc/libjpeg-6b/README
/usr/share/doc/libjpeg-6b/usage.doc
/var/cache/yum/base/packages/libjpeg-6b-37.i386.rpm
/var/cache/yum/base/packages/libjpeg-6b-37.x86_64.rpm

因此，我再次运行setup.py install ...并执行了selftest.py. 而且我仍然遇到相同的错误！

So, I ran setup.py install again...and did selftest.py. And I still get the same error!

推荐答案

您至少要安装3个标头集.如果您想与蒂芙(Tiff's)打交道，还需要1个

There at least 3 header sets that you will want to install. 1 more if you want to deal with Tiff's

freetype，libjpeg，zlib所有这些都将在CentOS上的以下软件包中提供:

freetype, libjpeg, zlib all of which will be in the following packages on CentOS:

== 32位: zlib-devel.i386 libjpeg-devel.i386 freetype-devel.i386

== 32 Bit: zlib-devel.i386 libjpeg-devel.i386 freetype-devel.i386

== 64位: zlib-devel.x86_64 libjpeg-devel.x86_64 freetype-devel.x86_64

== 64 Bit: zlib-devel.x86_64 libjpeg-devel.x86_64 freetype-devel.x86_64

与之前一样，您需要在setup.py文件中编辑以下变量:

As you did before you will want to edit the following variables in the setup.py file:

FREETYPE_ROOT JPEG_ROOT ZLIB_ROOT

FREETYPE_ROOT JPEG_ROOT ZLIB_ROOT

根据您的平台在此处将值设置为/usr/lib或/usr/lib64.完成后，您很可能希望运行

Setting there values to /usr/lib or /usr/lib64 based on your platform. Once done you will most likely want to run

python setup.py build --force
python setup.py install

这将强制为PIL重建所有库，然后将其原始安装.

That will force rebuild all your lib for PIL and reinstall them raw.
