Tip on Decoder JPEG not available (addition to docs ?)

[rouxxx]

Hi all,

This thread is about solving an issue. We all came across the "Decoder JPEG not available" error and many solutions can be found (libjpeg, etc...).

In my case, after numerous install/uninstall of Pillow and even more apt-get i was still stucked on this error.

It appears that pip cached the built setup in /root/.cache/pip/ (i was logged as root) so everytime i thought i was reinstalling Pillow, it just used the already compiled setup (without the necessary lib). I cleaned that directory and I was drowned by tears of joy as error was gone while my thumbnails appeared !

Thanks for Pillow, i can get back to normal life now... ;)

@rouxxx Great! Glad to hear, thanks. Yes we should add "clear cache" or something like it to the docs.

[hwms]

rm -rf ~/.cache/pip
tox -r 

worked for me at model_mommy

Thanks for that hint....had an equal sounding horror story several times when trying to get pillow to work ;P

I think Pillow's installation should abort with a fatal error if the JPEG and PNG libraries are not available, with platform specific instructions for the user to install the missing support libraries. Let's face it, if Pillow installs without these, it's broken.

Perhaps an override flag could be added for the 0.0001% of users who would consider an imaging manipulation library useful if it can't manipulate the two most common and important image formats.

@jbarlow83 Not a bad idea…

[njamaleddine]

@rouxxx I was having the same issue even after installing libjpeg on Ubuntu 14.04 x64. @katakumpo's solution rm -rf ~/.cache/pip worked well

[wiredfool]

@jbarlow83 Pillow 3.0 does not let you build without zlib(png) or libjpeg unless you explicitly ask for it.

[pauloxnet]

Can you add instructions to use "Build Options" (es: --disable-tiff) with "pip install Pillow" ?

[hugovk]

@pauloxnet This is already in the docs:

[wiredfool]

I don't think it's possible to use the disable options with pip, only with setup.py, and only then with the build_ext command.

[pauloxnet]

@hugovk I explicitly asked for information on the use of pip (I read the docs before asking) @wiredfool thanks for your reply. I just found this tips http://stackoverflow.com/a/31772244/755343 if it really works can you add this informations in Pillow's docs ?

[wiredfool]

I'm not sure that our docs need to be a reference on how to abuse pip. There's one way to do it, it's more obvious than using pip, and it's documented.

[pauloxnet]

Ok thanks for your reply

[aclark4life]

@pauloxnet @wiredfool Actually, I don't mind "pip hacks" however we should get someone from PyPA (https://github.com/pypa) to comment on this e.g. @dstufft. There is no mention of using build_ext with --global-option in pip's docs, however in order to decide on to-recommend-or-not we need to know how-good-or-bad this approach is according to PyPA. I don't fully understand the implications at the moment, but I like the idea of more-flexibility-with-pip vs. download-and-run-setup.py.

[pauloxnet]

@aclark4life thanks, I like the idea of more-flexibility-with-pip too.

[lorenzog]

This solved it for me on debian/ubuntu: apt-get install libjpeg-dev

[cham-il-k]

i had the same problem / and the warning about jpeg and the hint apt-get install libjpeg-dev solved my problem the ~ python setup.py install from the downloaded lreportlab compile very well

[voneiden]

The error message could be a bit more specific than "jpeg is required". But googling the error message lands now here, so I guess people will find their answers.

[lucabezerra]

I got here while trying to install mezzanine, but it was crashing when trying to install Pillow. The apt-get install libjpeg-dev tip also fixed it for me! Thanks :)

[x0lan]

Thanks @lorenzog! That worked for me also!

[haomingz]

CentOS can use yum install libjpeg-turbo-devel

[sryze]

How do you fix this on Windows? I was trying to install mitmproxy and came across this error. Removing %USERPROFILE%\AppData\Local\pip\cache didn't work for me.

[wiredfool]

Building on windows is complicated, you're much better off trying to use the prebuilt binaries that are on pypi.

[majodi]

sudo apt-get install libjpeg-dev fixed my reportlab install on Ubuntu also! Thnx

[jakirkham]

Running into this issue on Windows Python 3.4 32-bit only. Any thoughts?

I can give you logs, CIs, whatever you need to help diagnose/fix it. Here is a PR ( https://github.com/conda-forge/pillow-feedstock/pull/6 ) that gives you a head start on all of those things.

[wiredfool]

It's not a systemic issue on windows Py3.4/32. This is a recent appveyor master branch run on that platform: https://ci.appveyor.com/project/Python-pillow/pillow/build/3.3.pre.1131/job/v7nk6bgxpbutp6do

You might find this commit useful for debugging issues like this: https://github.com/python-pillow/Pillow/commit/80758e1bd7bf42ab6a62b63df57c386041e69bbd . It's not in 3.2, but it might help you find where things are going wrong.

[jakirkham]

Thanks @wiredfool. Will give that a try.

[jakirkham]

So, we tried the --debug flag and it appears to stop shy of telling us anything. Here is the relevant portion of the log.

You're not getting any stdout there, it should look something like this:

You're right. I thought I had fixed that issue, but I picked up a bad commit again. I'll need to table this one for a bit though and either I or someone else will pick this up when we have some more time. Thanks again for your help.

[zhan0483]

Finnally, it is working!!!!! Thanks!

I got problem decoder PNG / JEPG not avilable. Following works for me.

pip uninstall Pillow clear cache rm -rf ~/.cache/pip pip install Pillow=2.6.0
