This appears to be a Mojave Issue, I was able to resolve with:
sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /

To be clear, I'm guessing that 'key only' should be 'keg only'.

Were you able to install this fine prior to Mojave, or is this the first time that you have tried?

Do you have the Xcode command line tools installed? xcode-select --install

FWIW - I'm having same the issue -
Xcode CLI tools installed, Zlib installed from home-brew.
Mojave, Python 3.7

This appears to be a Mojave Issue, I was able to resolve with:
sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /

@choilive can you elaborate on this please? why is this a mojave issue?

dmitrybelyakov on 5 Nov 2018

don't know why but it works for me :) Thank @choilive for your suggestions.

postace on 6 Nov 2018

@dmitrybelyakov
I am not actually sure why but it appears that installing Xcode CLI Tools on Mojave does not actually install the Zlib headers - at least on the machines I have tested. Doesn't seem to be have been an issue on macOS 10.13 at least.

Manually installing the macOS SDK headers seem to add those headers.

@choilive
Yeah, that makes sense, thanks!

dmitrybelyakov on 7 Nov 2018

@benjamin-yin001 does the suggestion from @choilive help you?

radarhere on 7 Nov 2018

I can confirm the issue in Mojave ... the command from @choilive works here too

petschki on 9 Nov 2018

I too can confirm the issue in Mojave ... the command from @choilive works here too. Thanks dude.

freemanbot on 8 Dec 2018

Same... Had it worked in 10.13, fresh installed 10.14, and my set up script failed at pip install pillow with the error Could not find a version that satisfies the requirement zlib (from versions: ), even though i had zlib installed via homebrew.
Ran the command that @choilive posted, and ran pip install pillow and voila!
Thanks @choilive

pankajr on 17 Dec 2018

I had the same problem. the command from @choilive works here too

I ran into the issue just now. MacOS 10.14.2. Setting up a new machine and ran into the issue while installing Pillow==5.1.0.

I ran the command from @choilive and it did not fix the issue.

I was able to install Pillow==5.2.0.

I can confirm the problem Mojave 10.14.3

gvammer on 11 Feb 2019

For 10.14.3, @choilive's solution of running:

sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /

fixed the issue for me. My root issue was couldn't find an x11 header file.

bialecki on 4 Mar 2019

For 10.14.3, @choilive's solution is useful. Thanks.

wilson2young on 9 Mar 2019

Had the same issues after upgrading an application from python2.7 to 3. @choilive command helped but upgrading pillow to the current version was also necessary (5.4.1), otherwise an error about a missing JPEG library occurred. Previously installed pillow version was 4.1.1 which seemed not to be compatible with macOS 10.14.x and python3.

mgraupner on 26 Mar 2019

Same solution worked for me, thanks.

The macOS_SDK_headers_for_macOS_10.14.pkg install fix won't work on Catalina.

I did a bit of digging, and found this:
https://developer.apple.com/documentation/xcode_release_notes/xcode_10_release_notes#3035623

However, some software may fail to build correctly against the SDK and require macOS headers to be installed in the base system under /usr/include. If you are the maintainer of such software, we encourage you to update your project to work with the SDK or file a bug report for issues that are preventing you from doing so.

Where the /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg is a temporary workaround they're providing for macOS Mojave only:

As a workaround, an extra package is provided which will install the headers to the base system. In a future release, this package will no longer be provided

pyenv has a workaround that adds SDK headers to the lookup path: https://github.com/pyenv/pyenv/issues/1219#issuecomment-429331397

and pyenv eventually added formal support for the SDK: https://github.com/pyenv/pyenv/pull/1353

So I think this is an issue where Pillow will need to add the SDK path to the includes list when building from source.

Ran into this after a recent Xcode update on macOS Mojave 10.14.6. This time I did this, which also worked:

Installing the package file at /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg also works. IMO it’s cleaner - it puts the headers files where they belong, and prevents you from running into this in the future

https://twitter.com/FoleyDiver/status/1125477518998429697

open /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg and then follow the dialogs to install.

With _Mojave 10.14.6_ I had compilation and linkage errors and I followed this article to fix them https://donatstudios.com/MojaveMissingHeaderFiles

sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /

If you get an error about that file not existing, you probably simply don't have the Xcode command line tools installed which can be remedied simply as follows:

xcode-select --install

@choilive Thanks man, It solved the problem.

This saved me too after 2 days of googling. I had this issue on Mac
ld: library not found for -lssl
clang: error: linker command failed with exit code 1 (use -v to see invocation)
error: command 'gcc' failed with exit status 1

markoke on 19 Aug 2019

I solved this where the above approaches didn't work for me.

if using Tox like we are this is what I had to do (on a Mac):

Install openssl:
brew install openssl

add the exports to your shell e.g ~/.zshrc:

export LDFLAGS="-L/usr/local/opt/openssl/lib"
export CPPFLAGS="-I/usr/local/opt/openssl/include"

Then in your tox.ini under [testenv] you might find something that looks like this:

passenv=...

Include here the environment variables you want to pass to Tox e.g

passenv=
MYENV1
MYENV2
...
LDFLAGS
CPPFLAGS

And you're good to go. Just including the LDFLAGS and CPPFLAGS to your shell config should be fine if you're installing this to say a global python environment but the above is what I had to do for our local testing in with tox and pytest

Okay, so I installed XCode command-line tools (macOS 10.14) for Xcode 10.3 from https://developer.apple.com/download/more/ and it created Packages folder with macOS_SDK_headers_for_macOS_10.14.pkg

How do I "undo" this ? Uninstall this package you mentioned below, and revert back? Cuz this step won't work for my machine.
sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /

https://github.com/python-pillow/Pillow/issues/3438#issuecomment-523831923 works for me on Catalina 10.15.2 @JurajVajdaDeckers just skip the tox.ini config if not used, also use the correct rc file for your terminal interpreter e.g. ~/.bashrc vs ~/.zshrc or just export the variables before pip install ...

export LDFLAGS="-L/usr/local/opt/openssl/lib"
export CPPFLAGS="-I/usr/local/opt/openssl/include"

Also make sure to have installed openssl brew install openssl as @gigatexal solution mentioned

This worked for me on Catalina before pip install ...

I solved this where the above approaches didn't work for me.

if using Tox like we are this is what I had to do (on a Mac):

Install openssl:
brew install openssl

add the exports to your shell e.g ~/.zshrc:
export LDFLAGS="-L/usr/local/opt/openssl/lib"
export CPPFLAGS="-I/usr/local/opt/openssl/include"
Then in your tox.ini under [testenv] you might find something that looks like this:

passenv=...

Include here the environment variables you want to pass to Tox e.g
passenv=
MYENV1
MYENV2
...
LDFLAGS
CPPFLAGS
And you're good to go. Just including the LDFLAGS and CPPFLAGS to your shell config should be fine if you're installing this to say a global python environment but the above is what I had to do for our local testing in with tox and pytest

This solution worked for me on Mac Mojave 10.14.6. The solution using sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target / no longer worked.

If you get from Google trying to install pandas, try using a newer version (if you can). I tried all of the above and it didn't work, moved to pandas==1.0.3 and it worked right away.

Many people have posted in this issue, so I'll ask - are there problems in here unrelated to Homebrew? If not, then this issue should be resolved by #4842, and will be fixed with the release of Pillow 8.0 on October 15.
